Release 253/254: Normal 253 and Coordinates 254.
Download Super-Metroid-Plus-Windows-x64-253-254.zip for Windows or Steam Deck through Proton 10.0. Extract the entire folder and follow START HERE.txt. Supply your own matching Super Metroid (Japan, USA) ROM; no ROM or personal save is included.
This is a custom bsnes-hd-based emulator build with widescreen rendering and selected gameplay-boundary adjustments. It is not a native port or ROM patch. F8 toggles the diagnostic HUD in both launchers.
This pair fixes the Blue Brinstar scanner's angle-dependent widescreen dropout. The focused validation covers 1,850 native-equivalent targeted/regression frames, 25 probes, and an 8,472-frame GUI reference comparison for each build. This is bounded validation, not a guarantee of full-game compatibility or locked frame rates.
Back up saves before updating. Keep automatic updates off and use a separate folder for a new release. Normal and Coordinates share saves within their installation.
The runtime ZIP includes corresponding source and license notices; the source ZIP is also attached separately. SHA256SUMS.txt records both downloads. Public issues belong in this repository; older packaged instructions mentioning Discord refer to the earlier private playtest.
Quiver community catalog submission is pending. Manual repository addition uses peanutsofdoom/supermetroidplus and release asset filter Super-Metroid-Plus-Windows-x64; import your ROM before selecting Play.exe.
