Native PC build of Gumshoe (NES, Zapper) via NESRecomp.

Changes since v1.2

  • Stack-idiom fix: the recompiler now correctly models the 6502 "PLA/PLA/RTS = return two levels up" abort-caller idiom (9 sites in Gumshoe), preventing stack-pointer underflow.
  • Flicker fix: suppressed a spurious sprite-0 scroll split driven by the Zapper's heavy $2002 polling that jittered the platforms/ground frame-to-frame.

Install

  • Windows x64. Unzip and run GumshoeRecomp.exe. No ROM included — select your legally-obtained Gumshoe (USA/Europe) ROM on first launch.
  • Zapper: mouse mode is enabled — aim with the mouse, left-click to shoot.
  • Controls rebindable in keybinds.ini; F5 turbo, F6/F7 save/load state, F11/Alt+Enter fullscreen.
