Status

Gumshoe boots past the title screen and is playable end-to-end with mouse-as-Zapper input.

What changed since v1.0

This release pins nesrecomp at 07d1130 which adds two GxROM (Mapper 66) recompiler fixes that unlock playable gameplay:

  • GxROM per-window NMI vector dispatch. Each 32KB window has its own $FFFA-$FFFB. Previously the recompiler picked one window's vector at codegen time and used it for every NMI fire — which skipped OAM DMA + register saves on every frame for Gumshoe (boots into window 0 with NMI=$8031 but the recompiler defaulted to window 3's $8047).
  • GxROM-aware dispatch-table size scan. The inline_dispatch table-size scanner was looking up $C000+ targets in fixed_bank instead of the paired upper bank, truncating Gumshoe's 24-entry game-mode table at 18 entries — six gameplay states never executed.

Known issue

  • Top-left HUD elements (timer, shot counter) do not render. Gameplay itself is fully functional; this is cosmetic. Tracked in ISSUES.md.
