As of this release, the TIA is regression-free compared to Stella 4.x. So that means a final release is probably coming soon. Updates for this release include:
- Improved Ystart detection, taking care of final corner cases
- Fixed long-standing bug that caused a crash in Windows XP
- Further improvements to NUSIZ handling during hblank
- Many improvements to the RIOT timer emulation; this is now almost complete, and is more accurate than any other tested emulator (fixes lockups in Acid Drop, Panda Chase, Ski Hunt, Zoo Fun, etc)
- Fix rendering of bottom line in Canyon Bomber
- Reduced CPU usage in ROM launcher mode
- Improved autodetection of Superchip ROMs (Dig Dug is now properly autodetected)
- Cosmic Ark starfield effect now matches output from most common consoles
- Add ARM Timer 1 support, and BUS/CDF bankswitching schemes
- Improvements to RESMPx handling (fixes Ice Hockey, which was the last TIA regression from 4.x)
- State loading/saving is now working again
- Debugger rewind is working again
