v0.7.5

Blue Spheres quickstates now resume active and paused play in Sonic 3 & Knuckles and standalone Sonic & Knuckles, including fresh-process loads.

Modern saves checksum and replace immutable files in the background. The slot browser reports completion after replacement and preserves the previous slot and preview on failure. Diagnostic replay retains accepted save ordering. Valid long-running native loops no longer exhaust the cumulative dispatch budget; non-progressing loops retain the runaway guard.

Widescreen rendering corrects save-menu scenery, Competition lighting, card visibility, independently scrolling race margins, and competitor/start-pole visibility beyond the original viewport, special-stage sky intensity, and retained AIZ scenery and actor handovers. Standalone Sonic & Knuckles now verifies its canonical ROM checksum.

Includes all three games as Windows x64 ZIPs and Linux x86_64 AppImages. Fresh packages enable Fit widescreen. Existing explicit display choices, native in-game saves and settings are preserved.

The bundled Sonic 1 campaign allocates every authored Star Light scroll row, preventing a stack-buffer overflow.
