Fixes split vehicle explosions in Widescreen and reduces the CPU cost of HD Mode 7.
- Explosion and smoke sprites stay together when the game reuses rank-display sprite slots. Actual rank digits still anchor to the HUD. Supports fixed widescreen aspects, Fit, and native/2x/4x rendering.
- HD Mode 7 shares native/HD composition, caches scanline color math and repeated texture lookups, and uses faster texture wrapping. Recorded renderer benchmarks show roughly 2.5–3.3x faster rendering in the tested widescreen cases, with matching output hashes. Whole-application gains vary with resolution, CPU and presentation rate; see the measurements.
Download the Windows x64 ZIP or Linux x86_64 AppImage. Supply your own F-Zero (USA) ROM. BS F-Zero Deluxe remains included with its authors' permission. HD Mode 7 remains optional and off by default.
Validation: all nine test suites pass on Windows and Linux. The reported slot 01 explosion replay passes 228 captured frame/aspect/HD comparisons. Both packaged downloads pass stock and BS Deluxe race checks with HD off/4x, plus the slot 01 replay with HD off/2x/4x; final game memory matches between rendering modes.
