Over-Optimizing for Performance

Recently on the csharp subreddit, the post C# 9.0 records: immutable classes linked to a surprisingly controversial article discussing how C# 9.0's records are, underneath it all, immutable classes. The comments are full of back-&-forth over whether one should use records for ease or structs for performance. The pro-struct argument revolved around the belief that performance should always be a developer's #1 priority, and anything less was the realm of the laggard.
Here is a real-world example that shows with stark clarity why that kind of thinking is wrong.
Consider the following scenario:

1

You're working on a game with dozens, maybe hundreds of people on the team; you don't know because when you were cross with facilities about them removing all the fluorescents, you got accused of being against the new energy saving initiative. Now you swim in a malevolent ocean of darkness that on some very late nights alone in the office, you swear is actively trying to consume you.
 

2

The team that preceded you inherited an engine that is older than OOP, when source repositories were stacks of 8-inch floppies, and it looked as if Jefferson Starship was going to take over the world. One year ago they bequeathed upon the company this nightmare of broken, undocumented GOTO spaghetti & anti-patterns. You're convinced this was their sadistic revenge for all getting fired post-acquisition.
 

3

Management denied your request to get headcount for an additional technical artist, but helpfully supplied you with an overly nervous intern. After several weeks working alongside them, you're beginning to suspect they're pursuing something other than a liberal arts degree.
 

4

Despite the many getting started guides you spent countless evenings writing, the endless brownbags nobody attended, and the daily dozen emails you forward to oppressively inquisitive artists comprised of a single passive-aggressive sentence suggesting they scroll down to the part that begins FW: FW: FW: FW: FW: FW: RE: WE BROKE TOOL NEED WORKAROUND ASAP ...
 
...yes, despite all of that, the engineering team still spent days tracking down why the game kept crashing with Error 107221: У вас ошибка after re-re-re-re-re-throwing an ex_exception when it couldn't (and should never even try to) load a 16K-textured floor mat.
 

5

Despite your many attempts to politely excuse yourself, one blissfully unaware artist exhausts 48 minutes of your lunch break explaining how the Pitchfork review for the latest "dope slab" of this TikTok-Instagram-naphouse artist you never heard of was just sooooo unfair.
 
And then in their hurry to finish up & catch the 2:30 PM bus home, they forget to toggle Compress To CXIFF (Custom Extended Interchange File Format), set the Compression slider 5/6ths of the way between -3 & -2, look to their left, look to their right, click Export As .MA 0.9.3alpha7, and make absolutely, positively, 100% SURE not to be working in prod. And THAT is how the game explodicated.
 

6

You know better than anyone the intermediate file format the main game loop passes to Game.dll, memory mapping it as a reverse top-middle Endian binary structure.
 
You know for 381 of the parameter fields what their 2-7 character names probably mean.
 
YOU know which 147 fields always have to be included, but with a null value, and that the field ah_xlut must ALWAYS be set to 0 unless it's Thursday, in which case that blackbox from hell requires its internal string equivalent: TRUE.
 
YOU know that the two tech artists & one rapidly aging intern that report to you would totally overhaul tooling so artists would never "happen" again, but there just aren't enough winters, springs, summers, falls, July 4ths, Christmas breaks, Presidents Days, and wedding anniversaries in a year to properly do so.
 

7

If you could just find the time between morning standups, after lunch standups, watersprint post-mortems, Milbert's daily wasting of an hour at your desk trying to convince you engineering should just rebuild the engine from the ground up in JavaScript & React, & HR's mandatory EKG Monitor job satisfaction surveys, you might be able to get at least some desperately-needed tooling done.
 
And so somehow you do. A blurry evening or two here. A 3:00 AM there. Sometimes just a solitary lunch hour.
 
Your dog no longer recognizes you.
 
You miss your wife calling to say she's finally cleaning out the hall closet and if you want to keep this box of old cards & something in plastic that says Underground Sea Beta 9.8 Grade, you better call her back immediately.
 
And your Aunt Midge, who doesn't understand how SMS works, bombards you one evening:
your father is...
no longer with us...
they found him...
1 week ago...
in an abandoned Piggly Wiggly...
by an old culvert...
split up...
he was then...
laid down to rest...
sent to St. Peter's...
and your father...
he's in a better place now...
don't worry...
it's totally okay...
we decided we will all go...
up to the mountain
 
You call your sister in a panic and, after a tidal wave of confusion & soul-rending anxiety, learn it was just Hoboken Wireless sending the messages out of order. This causes you to rapidly cycle.
 

8

On your bipolar's upswing, you find yourself more productive than you've ever been. Your mind is aglow with whirling, transient nodes of thought careening through a cosmic vapor of invention. It's like your brain is on 200mg of pure grade Adderall.
 
Your fingers ablaze with records, clean inheritance, beautiful pattern matching, bountiful expression syntax, aircraft carriers of green text that generate the most outstanding CHM for an internal tool the world has ever seen. Readable. PERFECTLY SOLID.
 
After much effort, you gaze upon the completed GUI of your magnum opus with the kind of pride you imagine one would feel if they hadn't missed the birth of their son. Clean, customer-grade WPF; tooltips for every control; sanity checks left & right; support for plugins & light scripting. It's even integrated with source control!
 
THOSE GODDAMNED ARTISTS CAN'T FAIL. YOUR PIPELINE TOOL WON'T LET THEM.
 
All they have to do is drag content into the application window, select an options template or use the one your tool suggests after content analysis, change a few options, click Export, and wait for 3-5 minutes to generate Game.dll-compatible binary.
 
Your optimism shines through the commit summary, your test plan giddy & carefree. With great anticipation, you await code review.
 

9

A week goes by. Then two. Then three. Nothing. The repeated pinging of engineers, unanswered.
 
Two months in you've begun to lose hope. Three months, the pangs of defeat. Four months, you write a blog post about how fatalism isn't an emotion or outlook, but the TRANSCENDENCE of their sum. Two years pass by. You are become apathy, destroyer of wills.
 

10

December 23rd, 2022: the annual Winter Holidays 2-hour work event. The bar is open, the Kokanee & Schmidt's flowing (max: 2 drink tickets). The mood a year-high ambivalent; the social distancing: acceptable. They even have Pabst Blue Ribbon, a beer so good it won an award once.
 
Standing beside you are your direct reports, Dave "Macroman" Thorgletop and wide-eyed The Intern, the 3 of you forming a triumvirate of who gives a shit. Dave is droning on & on about a recent family trip to Myrtle Beach. You pick up something something "can you believe that's when my daughter Beth scooped up a dead jellyfish? Ain't that something? A dead jellyfish," and "they even had a Ron Jons!"
 
You barely hear him, lost as you are in thought: "I wish I had 2 days of vacation." You stare down ruefully at your tallboy.
 
From the corner of your eye you spot Milbert, index finger pointed upward, face a look of pure excitement.
 
"Did I tell you about my OpenWinamp project? It's up on SourceForge", he says as he strides over. It's unsettling how fast this man is.
 
"JAVASCRIPT IS JUST A SUBSET OF JAVA!" you yell behind you, tossing the words at him like a German potato masher as you power walk away. It does its job, stopping Milbert dead in his tracks.
 
Dave snickers. The Intern keeps staring wide-eyed. You position yourself somewhat close to the studio's 3 young receptionists, hoping they serve as a kind of ritual circle of protection.
 
It works... kind of. Milbert is now standing uncomfortably close to The Intern, Dave nowhere to be seen.
 
From across the room you distinctly hear "Think about it, the 1st-person UI could be Lua-driven Electron."
 
The Intern clearly understands that words are being spoken to them, but does not comprehend their meaning.
 
You briefly feel sorry for the sacrificial lamb.
 

11

You slide across the wall, putting even more distance between you & boredom made man. That's when you spot him, arrogantly aloof in the corner: Glen Glengerry. Core engineering's most senior developer.
 
Working his way up from a 16-year old game tester making $4.35 an hour plus free Dr. Shasta, to pulling in a cool $120K just 27-years later, plus benefits & Topo Chicos. His coding style guides catechism, his Slack pronouncements ex cathedra; he might as well be CTO.
 
You feel lucky your team is embedded with the artists. You may have sat through their meetings wondering why the hell you should care about color theory, artistic consistency, & debates about whether HSL or CMYK was the superior color space (spoiler: it's HSL), you were independent and to them, a fucking code wizard, man.
 
And there he stands, this pseudo-legend, so close you could throw a stapler at him. Thinning grey-blonde tendrils hanging down from his CodeWarrior hat, white tee with This Guy VIMs on the back, tucked into light blue jeans. He's staring out into the lobby at everything and yet... nothing all at.
 

12

Maybe it's the 4.8% ABV. Maybe it's the years of crushing down anger into a singularity, waiting for it to undergo rapid fiery expansion, a Big Bang of righteous fury. Maybe it's those sandals with white socks. Maybe it's all three. But whatever it is, it's as if God himself compels you to march over & give him a piece of your mind, seniority be damned.
 
"Listen, you big dumb bastard..."
 
That... is maybe a little too aggressive. But Glen Glengerry barely reacts. Pulling a flask out of his back pocket, he doesn't look over as he passes it to you.
 
Ugh. Apple Pucker.
 

13

"I thought bringing in your own alcohol was against company policy", wiping sticky green sludge from your lips. He turns with a look of pure disdain & snorts.
 
"You think they're going to tell ME what I can & can't bring in?" He grabs the flask back, taking a big swig.
 
For what feels like an eternity, you both stand in silence. You swallow, speaking softly. "None of you even looked at my code. I worked very, very hard on that. My performance review for that year simply read 'recommend performance improvement plan." The words need no further context.
 
"I know", Glen² replies. "That was me."
 

14

Now you're not a weak man, and maybe in some other circumstance you would have punched him in the goddamn lip. But you feel nothing, just a hollowness inside. "Why?", you ask, wondering if the answer would even matter.
 
"Because you don't use Bulgarian notation. Because your method names aren't lower camel case. Because good code doesn't require comments. Because you use classes & records over more performant structs, pointlessly burdening the heapstack. BECAUSE. YOUR CODE. IS. SHIT."
 
You clinch your fists so tightly the knuckles whiten.
 

15

He looks away from you, taking another sip of green goo. "You're not a coder. You're an artist masquerading as one" he speaks, as if it were fact.
 
The only thing artistic about you is the ability to create user-friendly internal tooling using nothing but a UI framework, broken down garbage nobody wants to touch, & sheer willpower. If your son's life depended on you getting accepted into art instruction school, you couldn't even draw a turtle.
 
He doesn't pause. "I'll champion ruthless micro-optimization until the day I die. But buddy, I'm going to let you in on a little secret: you aren't here to improve workflow. You're here to LOOK like you're doing something NOBODY else can."
 
He goes on. "What do you think those artists are going to do when they have to stare at a progress bar for 4, 5 minutes? They're going to complain your tool is slow."
 
"Sure, it may take them 20, 30 minutes to do it the old way, there'll be an error, and either they'll stare at it for 30 minutes before adding that missing semi-colon or they'll come get you. And you'll fix it. And 1 week later, they won't remember how. And you'll stay employed. And every. Body. Wins."
 

16

A little bit of the pride, the caring, wells back up inside from somewhere long forgotten.
 
"You don't think we should care about rapid application development & KISS, quickly getting things out that help our team, instead devoting ourselves to shaving off ticks here & there? What do you think artists are going to do with those 4 minutes you talk about?
 
You don't stop. "I'll tell you what they'll do. They'll 9GAG for 20 minutes straight. They'll listen to podcasts about dialectical materialism vis-a-vis the neo-feudalism that is a natural extension of the modern world's capitalist prison. They'll Reddit."
 
His silence gives you the bravery to push the limits.
 
"Christ, man. Are you only in it for the $120K..."
 
He corrects you: "...$123K."
 
"...only in it for the $123K/year? The free snacks from the microkitchen? The adulation? Have you no sense of comraderie?? No desire to push us to something better?! No integrity?!!!"
 
His eyes sharply narrow, face creases in anger. You clearly have overstepped your bounds.
 

17

"You think I don't have integrity? No sense of teamwork? I'm only in it for the cold cash? You think I don't care about you all?", he roars.
 
A light volley of small green flecks land on your face.
 
"Why do you think they made a 16-year old tester the lead developer of a 1993 Doom clone?! Because my code was clean & painless to work with?! Because I made coding look easy?! No! IT WAS BECAUSE I WAS A GOD TO THEM.
 
And from a God, a PANTHEON. We built monuments to over-engineering! We crafted that of 7 weeks onboarding, that of immortal bugs, demonic hosts spawned by legion from the very loins of a fix. It took 2 years before a developer could BEGIN to feel confident they knew what they were doing. And by that time, they were one of US!
 
You think the team we laid off November '19 was fired because they were bad at their jobs? NO! It was because they worked themselves out of one. They didn't leave us a broken pipeline. They left an internal Wiki, a wealth of tools & example projects, and a completely transparent code base.
 
We couldn't have THAT, now could we? No, we couldn't. So we got rid of it. ALL OF IT. Poof. Gone. Just like that. Before anyone even knew a THING."
 
He leans forward, so close his psoriasis almost touches yours.  
With an intensity that borders on frightening, he whispers "You think they left us Game.dll? I fucking *MADE** Game.dll."*
 
The words hit hard like a freight train.
 

18

And without another word, he turns & leaves. You're left there, alone, coworkers milling about, with only one thought.
     
Were one to get a hobby, should it be cocaine?
 

In Conclusion

It's these kinds of situations that make me believe there are far more important considerations than a ruthless dedication to performance, even in the game industry as my real-world scenario so clearly demonstrates.
 
Like, records are cool & shit.

Cross-compiling to AVR with clang

Hi,
I am trying to cross-compile a C++ file to AVR using clang. I am running Ubuntu from a windows laptop using WSL. I am using clang built from source to enable AVR support.

I checked that AVR was indeed a registered target by running the command llc --version.
Here is the output running llc --version:
LLVM (http://llvm.org/): LLVM version 12.0.0git Optimized build. Default target: x86_64-unknown-linux-gnu Host CPU: skylake Registered Targets: aarch64 - AArch64 (little endian) aarch64_32 - AArch64 (little endian ILP32) aarch64_be - AArch64 (big endian) amdgcn - AMD GCN GPUs arm - ARM arm64 - ARM64 (little endian) arm64_32 - ARM64 (little endian ILP32) armeb - ARM (big endian) avr - Atmel AVR Microcontroller [...] 
Here is a screenshot (imgur) of the terminal as well.

When I try to compile a simple C++ file, it fails to link. You can find the code I am trying to compile here (pastebin).
This is the command I run to compile: [path-to-custom-build-of-clang] -Os -std=c++17 -fno-exceptions -ffunction-sections -fdata-sections -fno-threadsafe-statics -flto --target=avr -mmcu=atmega328p -DF_CPU=16000000L -DARDUINO=10813 -DARDUINO_AVR_UNO -DARDUINO_ARCH_AVR blink.cpp -v
This is the error I get when running the said command:
clang-12: warning: no avr-gcc installation can be found on the system, cannot link standard libraries [-Wavr-rtlib-linking-quirks] clang-12: warning: standard library not linked and so no interrupt vector table or compiler runtime routines will be linked [-Wavr-rtlib-linking-quirks] clang version 12.0.0 (https://github.com/llvm/llvm-project.git e1c38dd55d9dab332ccabb7c83a80ca92c373af0) Target: avr Thread model: posix InstalledDir: [path-to-custom-clang-build-directory] clang-12: error: 'avr': unable to pass LLVM bit-code files to linker 
Here is a screenshot (imgur) of the terminal as well.
I have tried specifying the path to the linker with the argument --ld-path but I got the same error.

I have read somewhere that the option -flto was not supported, so I tried the same command minus the -flto option.
Here is the output of compiling without -flto:
clang-12: warning: no avr-gcc installation can be found on the system, cannot link standard libraries [-Wavr-rtlib-linking-quirks] clang-12: warning: standard library not linked and so no interrupt vector table or compiler runtime routines will be linked [-Wavr-rtlib-linking-quirks] clang version 12.0.0 (https://github.com/llvm/llvm-project.git e1c38dd55d9dab332ccabb7c83a80ca92c373af0) Target: avr Thread model: posix InstalledDir: [path-to-custom-clang-build-directory] "[path-to-custom-clang-build-directory]/build/bin/clang-12" -cc1 -triple avr -emit-obj --mrelax-relocations -disable-free -disable-llvm-verifier -discard-value-names -main-file-name blink.cpp -mrelocation-model static -mframe-pointer=all -fmath-errno -fno-rounding-math -mconstructor-aliases -target-cpu atmega328p -fno-split-dwarf-inlining -debugger-tuning=gdb -v -ffunction-sections -fdata-sections -resource-dir [path-to-custom-clang-build-directory]/build/lib/clang/12.0.0 -D F_CPU=16000000L -D ARDUINO=10813 -D ARDUINO_AVR_UNO -D ARDUINO_ARCH_AVR -Os -std=c++17 -fdeprecated-macro -fdebug-compilation-dir [path-to-project]/source -ferror-limit 19 -fgnuc-version=4.2.1 -fno-threadsafe-statics -fcolor-diagnostics -vectorize-loops -vectorize-slp -faddrsig -o /tmp/blink-1f28ec.o -x c++ blink.cpp clang -cc1 version 12.0.0 based upon LLVM 12.0.0git default target x86_64-unknown-linux-gnu #include "..." search starts here: #include <...> search starts here: /uslocal/include [path-to-custom-clang-build-directory]/build/lib/clang/12.0.0/include /usinclude End of search list. "/usbin/avr-ld" /tmp/blink-1f28ec.o -o a.out --gc-sections 
Here is a screenshot (imgur) of the terminal as well.

It does produce a binary file; however, when checking the size, it outputs zero.
This is the output of llvm-size ran on the output binary a.out:
 text data bss dec hex filename 0 0 0 0 0 a.out 
And sure enough, when I try to upload it with AVRDude, nothing gets written and nothing happens.

I can compile the same program using gcc (built from source) upload it and run it on an Arduino board.
Finally, the question, are there people who have run into similar issues when trying to cross-compile to AVR and more importantly, how did you solve them?
If you are missing pieces of information to understand the situation, I am happy to provide more details.
Cheers.

Describing data streams

I've had some thoughts about file extensions and MIME types, and how inadequate they are at telling the OS, applications or humans anything truly useful about type of data in a file or stream, and how to improve the situation.
A good example might be Application/pdf - which tells you very little. It doesn't say that it's ultimately a page layout, or a human readable document, or that it's binary.
A file or stream can also be viewed as different types depending on how high or low level you are considering it. For example, an SVG image is also an XML document, which is also a text stream. This could be useful information for a system, which even if it doesn't know what to do with SVG, it may still be able process it as an XML stream.
There's also extra information that usually has to be determined heuristically each time a file is opened, such as the character encoding of a text file, the endian-ness of the byte order for multi-byte values, and whether the text is left-to-right or vice versa.
All of this useful information could be assembled to describe a data stream in a meaningful way, which has lead me to propose some examples of how this could look.
A plain text file, could be described thus:
text(charset:iso-8859-15;line:CRLF;dir:LTR) 
A CSV file, which has always been plagued with difficulties as there's no way of marking the many optional configurations, could be described something like this:
text(charset:iso-8859-1;line:CRLF)/data/csv(delimiter:",";text-enclosure:"\\"";date-format:"YYYY-MM-DD") 
An SVG image as in interesting case as at least two separate descriptions could apply:
text(charset:utf-8;line:LF;dir:LTR)/data/markup/tag-based/xml, text(charset:utf-8;line:LF;dir:LTR)/visual/vectosvg 
You could opt for a more encapsulated notation instead, which would be well demonstrated by a compressed SVG (.SVGZ is a commonly used file extension for these):
binary/compressed(type:gzip){ visual/vectosvg{ markup/tag-based/xml{ text(charset:utf-8;line:LF) } } } 
Such descriptions could be examined by programs which could then decide if they're capable of consuming or handling the data even if not at every level.
Would anyone be interested in exploring this idea further, with a look to perhaps defining a useful language for describing data streams?

MAME 0.218

MAME 0.218

It’s time for MAME 0.218, the first MAME release of 2020! We’ve added a couple of very interesting alternate versions of systems this month. One is a location test version of NMK’s GunNail, with different stage order, wider player shot patterns, a larger player hitbox, and lots of other differences from the final release. The other is The Last Apostle Puppetshow, an incredibly rare export version of Home Data’s Reikai Doushi. Also significant is a newer version Valadon Automation’s Super Bagman. There’s been enough progress made on Konami’s medal games for a number of them to be considered working, including Buttobi Striker, Dam Dam Boy, Korokoro Pensuke, Shuriken Boy and Yu-Gi-Oh Monster Capsule. Don’t expect too much in terms of gameplay though — they’re essentially gambling games for children.
There are several major computer emulation advances in this release, in completely different areas. Possibly most exciting is the ability to install and run Windows NT on the MIPS Magnum R4000 “Jazz” workstation, with working networking. With the assistance of Ash Wolf, MAME now emulates the Psion Series 5mx PDA. Psion’s EPOC32 operating system is the direct ancestor of the Symbian operating system, that powered a generation of smartphones. IDE and SCSI hard disk support for Acorn 8-bit systems has been added, the latter being one of the components of the BBC Domesday Project system. In PC emulation, Windows 3.1 is now usable with S3 ViRGE accelerated 2D video drivers. F.Ulivi has contributed microcode-level emulation of the iSBC-202 floppy controller for the Intel Intellec MDS-II system, adding 8" floppy disk support.
Of course there are plenty of other improvements and additions, including re-dumps of all the incorrectly dumped GameKing cartridges, disassemblers for PACE, WE32100 and “RipFire” 88000, better Geneve 9640 emulation, and plenty of working software list additions. You can get the source and 64-bit Windows binary packages from the download page (note that 32-bit Windows binaries and “zip-in-zip” source code are no longer supplied).

MAME 0.219

MAME 0.219

MAME 0.219 arrives today, just in time for the end of February! This month we’ve got another piece of Nintendo Game & Watch history – Pinball – as well as a quite a few TV games, including Dream Life Superstar, Designer’s World, Jenna Jameson’s Strip Poker, and Champiyon Pinball. The previously-added Care Bears and Piglet’s Special Day TV games are now working, as well as the big-endian version of the MIPS Magnum R4000. As always, the TV games vary enormously in quality, from enjoyable titles, to low-effort games based on licensed intellectual properties, to horrible bootlegs using blatantly copied assets. If music/rhythm misery is your thing, there’s even a particularly bad dance mat game in there.
On the arcade side, there are fixes for a minor but long-standing graphical issue in Capcom’s genre-defining 1942, and also a fairly significant graphical regression in Seibu Kaihatsu’s Raiden Fighters. Speaking of Seibu Kaihatsu, our very own Angelo Salese significantly improved the experience in Good E-Jan, and speaking of graphics fixes, cam900 fixed some corner cases in Data East’s innovative, but little-known, shoot-’em-up Boogie Wings. Software list additions include the Commodore 64 INPUT 64 collection (courtesy of FakeShemp) and the Spanish ZX Spectrum Load’N’Run collection (added by ICEknight). New preliminary CPU cores and disassemblers include IBM ROMP, the NEC 78K family, Samsung KS0164 and SSD Corp’s Xavix 2.
As always, you can get the source and 64-bit Windows binary packages from the download page.

MAME 0.216

MAME 0.216

With the end of November in sight, it’s time to check out MAME 0.216! We’ve addressed the reported issues with last month’s bgfx update, and made a whole lot of little improvements to MAME’s internal user interface. In particular, setting up controls should be easier, and several issues affecting macOS users with non-English number format settings have been fixed. Some of the issues caused bad settings to be written to INI files. If you still don’t see the filter list panel on the system selection menu, try removing the ui.ini file.
This month, we’re able to present two unreleased 1970s prototypes from Italian developer Model Racing: their internal code names are Cane and Orbite. With the assistance of former Model Racing employees, the source code was extracted from the original disks. These games are incomplete, but they provide a unique look into early CPU-based arcade development. Game & Watch titles continue to be emulated, with the addition of Mario The Juggler, and the panorama screen Mickey Mouse and Donkey Kong Circus games in this release.
This release brings GameKing emulation to MAME. The system-on-a-chip used in this low-cost, low-resolution hand-held console from the early 2000s has been identified and emulated. Games for the colour-screen GameKing III are also playable. Acorn BBC Micro emulation has been re-worked to support internal expansion boards, and a number of additional peripherals are now available. ZX Spectrum emulation has been enhanced with better open bus read behaviour and support for two Miles Gordon Technology peripherals.
Of course, these are just the highlights. You can get the source and Windows binary packages from the download page.

MAME 0.217

MAME 0.217

What better way to celebrate Christmas than with a new MAME release? That’s right – MAME 0.217 is scheduled for release today. Just a reminder, this will be the last MAME release that we distribute a pre-built 32-bit Windows binary package for. Compiling for 32-bit targets will still be supported, but you’ll have to build MAME releases yourself starting from next month. This will also be the last release with source code distributed in the “zip in zip” archive format. We recommend getting source code by cloning a tagged revision from one of our version control mirrors (GitHub, GitLab or SourceForge), or you can use the P7ZIP tools to extract the self-extracting 7-Zip source archive. For MAME 0.217, we’ve switched the Windows tool chain to GCC 9.2.0, and uploaded an updated tools package (the minimum supported GCC version has not changed).
With all the housekeeping announcements out of the way, we can get to those juicy updates. The most exciting thing this month is the recovery of the Sega Model 1 coprocessor TGP programs for Star Wars Arcade and Wing War, making these games fully playable. We’ve been working on Virtua Fighter as well, and while the graphics are greatly improved, there are still some gameplay issues as of this release. In other arcade emulation news, sasuke has been busy fixing long-standing graphical issues in Nichibutsu games, and AJR has made some nice improvements to the early SNK 6502-based games.
On the home system side, there are some nice Sam Coupé improvements from TwistedTom, support for Apple II paddle controllers, a better Apple II colour palette, and significant improvements to Acorn RiscPC emulation. TV game emulation is progressing steadily, with two Lexibook systems, the Jungle Soft Zone 40, and the MiWi 16-in-1 now working.
For front-end developers, we’ve added data to the XML list format allowing you to handle software lists enabled by slot card devices (there are a few of these for Acorn and Sinclair home computers). The minimaws sample script has been updated to demonstrate a number of tasks related to handling software lists. For MAME contributors, we’ve made save state registration a bit simpler, and more manageable in the debugger.
You can get the source and Windows binary packages from the download page.
