Super Mario Bros. 1.12.4

Updated to NESRecomp 0.4.3 at 721c68c313e729710203f6825e9bcb9042eb5bcc. This Windows x64 build retains the qualified native PPU/APU services and packed PPU path. The matched stock workload has a modest 2.74% median CPU reduction.

Performance figures describe five alternating 1,200-frame gameplay pairs with independent pre/post baseline controls on the same host, SDL software rendering and emulated/mixed/queued audio through dummy output. Expanded custom-mode timing is unverified; no every-mode performance claim.

All 124 generated C units across the release suite match the qualified generator output. This exact shipping executable passes 720-frame old/new hardware, PCM, picture and current-build save/load replay comparisons, in addition to the earlier full 13-profile feature gate and owner visual approval. Native in-game saves remain separate from disposable build-specific execution snapshots.

One archive contains the game, required runtime libraries and optional mod catalog. No ROM, owner settings or saves are included.

Full validation and measured scope.
