I know of a :filez: site, I just point it to my existing romset and it checksums and downloads all the new ones for the current version of mame. There’s a half TB of CHDs, many of which are Bemani titles, which may or may not be what you want.

Those MESS software sets are only mildly interesting for looking at though. There’s like a million computer chess devices they emulate, and you come across an emulation for a Russian VT220 terminal. I think I’d rather use a dedicated emulator for something like the C64 or Apple II

Today I learned that Killer Instinct arcade is the first arcade game to use a hard disk drive and it’s about 100 MB in size including the ROMs.

Turns out, even though the hardware is labeled “Ultra 64”, it’s a proprietary one off, that’s good at sprite scaling and movie playback, but I’m not sure it even has hardware polygon support or if they fake it

The same sort of thing happened with Crusin’ USA, arcade has nothing to do with Nintendo hardware, not even like the Triforce Board where it’s an over clocked GameCube with extra ram

This boot screen and chip test is typical of midway games (Mortal Kombat, Revolution X) of the era

Plays on at a locked 60 FPS on my 8700k but the real game has an analog steering wheel with force feedback, analog pedals, shifter knob, lit buttons to select views ... just about the opposite of “just plug in any old USB controller”

That was it! Thank you so much.

Another MAME question if I may.

I noticed on my 4ghz core i7 (an old one, but still), Marvel vs Capcom 2 runs at like, no exaggeration, 8 fps.

I am looking at task manager while it's running and MAME is only using up 12% of the CPU while running this game.

Shouldn't the CPU be running at near 100% since it's struggling so much?

Mame is meant to be a hardware preservation project, so accuracy above all - which means no speed hacks or offloading rendering to GPUs, everything is in software, more or less hardware agnostic. GPU tech changes year by year and ensuring the hundred or so 3d systems mame emulates works with the dozens of cards available today is just too much.

12% - have a look at the individual cores, one should be pegged at 100%. Again, single threaded, accuracy above all, all frames are rendered exactly as they are on original hardware, even if it's 8 FPS.
I thought it was a drat miracle that Crusin' worked as well as it did.

Solution - specialized emulator, or get a CPU with higher individual core performance; I wonder how well MAME runs on an Apple M1?

The Kins posted:

I want to say there are plans to use Vulkan or GPU computing or something to offload the rendering to the GPU while still doing it in the software style, but I'm not sure whether those plans are being acted on or not.

Here's a bit about software 3d rendering I really only looked at the background section.
https://docs.mamedev.org/techspecs/poly_manager.html

but it seems to be about breaking out rendering into its own thread, which would be a great first step to taking pressure off the (and boy, does this suck) single core of CPU and offloading onto GPU.
But:
"If the emulated system has a mechanism to read back from the framebuffer after rendering, then a wait must be issued prior to the read in order to ensure that asynchronous rendering is complete."

it's system specific, any gains from async rendering can go out the window...

Odd choice of games but this is the perfect replacement if your board has been rotted out by leaky capacitors

I got digital eclipse’s Atari 50 but that’s as far as my nostalgia goes.

Always liked Voultar’s diagnosing and restoration videos from five years ago. But, when it gets to identifying and restoring corroded traces on a PCB it looks like a real difficulty cliff.

Looks comparable to a vewlix https://vewlixshop.com/product/street-fighter-v/ arcade setup, for a third of the price.

I probably wouldn't be so viscerally disappointed in LCD monitor replacements in CRT cabinets if the monitor ever actually fit or didn't look completely out of place.

There's a few cabinets with horizontally mounted monitors that reflect the display on a mirror. Would those look bad if their CRTs were replaced?
