Current build and known issues
RC3 sound + CMOS fixes · 2026-09-22
Beta; cabinet verified; timing waiver (slow -40C corner)
Smash TV, Trog, High Impact, Super High Impact, Strike Force and Saurian Front. Fixes silent sound at power-on (6809 sound CPU cold reset) and the CMOS INVALID hang on a blank save (factory CMOS built into the MRAs); blitter bit-exact against MAME. Timing misses only the slow -40C corner by 0.018 ns.
These statements describe the published core build. They do not establish that every supported game has passed every cabinet test.
