Sonic 3 family v0.5.1 — Widescreen file select
Patch release for Sonic 3, Sonic 3 & Knuckles, and Sonic & Knuckles,
with Windows x64 ZIPs and Linux x86_64 AppImages. Supply your own matching ROM.
Changes
- Data Select in Sonic 3 and Sonic 3 & Knuckles now extends its portrait
backdrop across Adaptive and fixed widescreen views, replacing black margins. - Extra space shows the actual neighboring save cards and their characters.
The card strip stops at its ends instead of repeating unrelated cards. - The expanded composition stays intact during menu fades. Native center
pixels and selection behavior are preserved.
All v0.5.0 fixes and mods are included. Widescreen and Knuckles remain opt-in
under Mods; Widescreen → Adaptive follows the window size.
Upgrading
Extract the complete Windows ZIP. On Linux, make the AppImage executable and
run it from a writable folder; use --appimage-extract-and-run without FUSE.
Linux requires Ubuntu 24.04 (glibc 2.39) or a compatible x86_64 system.
Keep settings.ini, rom-*.cfg, *-mods.ini and cartridge saves (*.srm).
Save states require the same build and configuration; use cartridge saves to
carry progress between releases.
Validation
The file-select change was checked at native, 16:9, 32:9 and 64:9 widths,
including every card, both ends and the return-to-title fade. Across 120
captures, game RAM/VRAM stayed identical and native center pixels were retained.
Release validation covers all 13 attract selections, file-select scrolling,
mod gameplay and both packaged launchers, with Windows/Linux pixel and state
comparisons. Each package contains source/dependency metadata and licenses;
SHA256SUMS.txt covers all six downloads.
The experimental widescreen and gameplay limitations documented in
v0.5.0
still apply, including the separately tracked longer IceCap Act 1 route.
