    Unibios ADPCM-B Channel Swap Possible?

    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...

    Neo Geo homebrew status & WIP (Xevious etc)

    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...

    CPS1 palette copy weirdness

    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...

    Xevious for the Neo Geo Beta 1 released!

    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)?!?

    Xevious for the Neo Geo Beta 1 released!

    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)...

    Tonight I started my new homebrew project...

    Tonight I started my new homebrew project...

    Someone gave me an idea to use CDDA for some of the tracks. I guess that would be the equivalent of ADPCM-B... I think that would work for me and minimise the changes in the code as most of the differences (aside from mute/unmute and stop loop) are handled implicitly by NFX SoundBuilder...

    Tonight I started my new homebrew project...

    I've finished the sound reorganisation for the NGCD and the sound is complete. Unfortunately the 1 glaring difference between the arcade and the Neo Geo version is that the rumbling sound of the Andor Genesis mutes the Solvalou theme. This is because NGFX SoundBuilder allows only 1 background...

    Tonight I started my new homebrew project...

    I've reorganised the sound to use ADPCM-A only, but I think the Andor Genesis sound will cause a problem.... TBA... Can't find this pesky gameplay bug. It's like there's an invisible Bacura... otherwise it's looking and sounding great!!!

    Tonight I started my new homebrew project...

    Hmmm... discovered tonight that NGCD doesn't have ADPCM-B. Not a show-stopper, but something to tweak none-the-less...

    Another quick update; Beta release is very close, with the one gameplay bug still outstanding. But - there will be (some) sound in the Beta release!!!
