Artwork available


- Corrupted music after completing first several levels. tamacula (ID 00785)

- 6th May 2007: Mr. Do - Cleaned up the cabaret bezel version of Omega Race, thanks to the BYOAC/CAG artwork. The overlay for Omega Race was based on various photos and RGVAC discussions.

- 0.108u5: Mathis Rosenhauer rewrote the Atari vector generators, using the schematics and actual state machine PROMs. The state machine is now emulated so timing should be much more realistic. Clipping hardware in bzone and others is emulated instead of hardcoded. Improved accuracy of clocks and various other bits of cleanup. Added prom ($0 - DVG PROM).

- 25th August 2006: Mr. Do - Updated Omega Race with a new scan from Eric at TAFA, which now includes the speaker grill above the bezel.
