It's in the works...

Not sure any (program) hack would be possible, even per-game. The ADPCM left and right channel values are interleaved, and the hardware itself reads it from memory based on start/end addresses (with 256-byte granularity) programmed into the registers. There's no data path between the VROM and...

I don't see how it could, no.

Beta 1 available for download now (MAME only atm, although you're free to convert to NeoSD/Darksoft or burn a CD if you are able). Enjoy!

Nah, the best way to ruin your hobby is to make it your job... :sneaky:

Xevious Beta 2 release (including Super Xevious) is still waiting for me to fix some sound issues. I've been distracted... There are a few other projects in the works, including an imminent Beta release of Galaxian. During the development of Xevious I was working with jotd of Amiga fame to...

Donkey Kong is WIP and hasn't been released yet...

I know nothing about the CPS, but is the palette data (either source or destination) done via address/pointer registers that may be modified in the VBLANK ISR? I ask this because on the Neo Geo all sprite registers are done via VRAM address registers, so you must be careful to disable the VBLANK...

Work on the next beta is continuing. I now have both Xevious and Super Xevious running from the same cart image.

Much appreciated! Working on the next (hopefully final) Beta...

Thanks, I try to contact @iq_132! I didn't specify a screenshot in NeoBuilder so not sure why it picked that one up. TBH didn't even notice on my NeoSD... IIUC you can't specify a (custom) screenshot in homebrew games (yet)?!?

I haven't tried myself (my MiSTer has a broken BlisSTer board) but I do believe it is possible. It'd be really nice if they added rotation to the Neo Geo core (last time I looked it didn't have it)...

The download now includes the Darksoft image!

Get it while it's hot!!! For MAME, NeoSD and NGCD. Runs in tate mode! Download on itch.io

Woohoo - found the "last" gameplay bug! Now to do some final playtesting of the the Beta1 builds (AES/NGCD) on real hardware before I release!
