Repository navigation
Built from the community's reports on the launch thread. Every reporter is credited in the README; the full audit with numbers is in docs/AUDIT-2026-09-05.md.
Performance
- Interpreter fallback eliminated: the game's hot code (including the block it copies into ITCM) is now compiled into native banks from on-device coverage. Same 90 s intro window on the dev Thor: 37 -> 58 fps average, emulation 28.6 -> 12.3 ms/frame, interpreted instructions 7.5M/s -> ~600/s.
- Audio: underruns 2,019 -> 110 per 90 s (3x); 125 ms runway; starvations fade instead of click.
- Post-save slowdown fixed: the save was written synchronously per SPI transaction; now debounced.
- 3x internal resolution is the recommended Thor setting (labelled in the menu; 4x explained).
Controls and screens
- Controls work immediately on the title screen (two causes fixed: the capture gate, and the bottom-screen window taking input focus).
- True fullscreen (nav bar hidden). Bottom screen in Original 4:3 with a Stretch option; touch mapped correctly in both.
- Second-screen companion while the launcher is open: live controller map of your bindings.
RetroAchievements
- Built-in rcheevos client: login (token kept), hardcore mode, unlock pop-ups, achievements browser in settings, optional RA strip on the bottom screen (off by default, 4:3 only).
- Hash note: RA links only the rev 1 hash to this game; the app has an opt-in switch that reports it so the set loads, with the consequences stated on the switch. The clean fix is a hash-link request to RA for rev 0.
Diagnostics
- Engine-true FPS counter, Share Diagnostics zip for bug reports, ROM locate/verify flow, version badge with update link, settings that prove what they applied in the log.
Same rule as always: your own USA rev 0 dump (SHA-1 90164d1ac127ee5f9815ea4ae7de798c7b5fc629); no game data distributed. Step-by-step reference setup in the README.
