mame VS mame

Yes, there are many challenges in reverse engineering these classic games. This is a good example.

Living in L.A. in the 90's, I remember Pack Mann in Pasadena had this one.

The ROM dump's been done but people seem to be stuck on the RLE encoding. It's hard to say what kind of wizardry is needed in this case.

There's a good start at it in the tree ( https://github.com/mamedev/mame/blob/master/src/mame/yamaha/... ) but it's missing the sound generation which is kind of the important part :-)

> As requested by users, you can finally use delta CHD files for clone systems and software items. This allows for major disk space savings in some cases when you have multiple versions of a system or software item.

FWIW, this is commit https://github.com/mamedev/mame/commit/d1172bf710f2a7b1777ed...

The GitHub Actions workflow bgfxshaders.yml will rebuild the shaders and then zip them up as an artefact. If you push your shader changes to GitHub and let the workflow run, you can grab the rebuilt shades from there.

Note that the process of getting the MSYS64/MinGW build environment set up is simple enough that we have automated CI builds for it on GitHub Actions without needing any custom actions of our own.

I assume they’re free vend because they’re MAME based?

You can try this fork as well: https://github.com/987123879113/mame/wiki It's not officially supported, but the MAME dev who has been doing a ton of the 573 emulation work did this on the side.

SIO1 isn't properly emulated which stops beatmania IIDX 1st from booting (the DVD player error) and stops various Sys573 games from being playable: Martial Beat's I/O uses SIO1, Mambo a Go Go's rental system device uses SIO1, GFDM's card readers and multisession unit use SIO1. The system connection between beatmania IIDX and DDR also uses SIO1. In my branch I repurposed the i8251's code as a separate SIO1 device in my branch but in the process I think I broke P1's memory card when trying to use the branch as a PSX emulator directly. https://github.com/987123879113/mame/blob/bemani/src/devices/cpu/psx/sio.cpp

As u/546897126 pointed out this cab isn't for MAME. I honestly posted this to put eyes on the cab and to put interest on Bemani MAME fork. Had to keep it relevant to the r/MAME sub

OS - Windows autobooting Big Box(Launchbox) which has Stepmania, running a commissioned vertical theme and a few arcade games that make full use of the vertical screen, while being able to center player 1 with this patcher. As well as a fork of MAME and a fork of PSCS2 playing their respective arcade games without audio/video sync issues.

I have a personal branch for all of my WIP Bemani-related changes (and some stuff that can't be upstreamed since it's hacky), which includes an "Audio offset" in the sliders menu: https://github.com/987123879113/mame/tree/bemani
