I love this game both arcade or 8bit conversion. If you have any plan for the music/fx, I'd love to contribute somehow... I've ripped the PCM data from the arcade so we have some voices and a crash fx. *in the zone
If anyone dares with the music, you can play the arcade rom directly with HOOT SOUND HARDWARE EMULATOR. It can mute channels and dump to wav if needed.
Good luck and glad to see new ports to our miggies.
