• MFi+ modifier swap-modes — Saturn, 32X, GameCube, Jaguar — Extends controller mappings to expose missing inputs on GCGamepad/extended gamepad profiles:
  • Saturn (Mednafen, GCGamepad): Hold L1+R1 modifier — DPad Up → L trigger, DPad Down → R trigger, A → Start. D-pad Up/Down and shoulder buttons (C/Z) suppressed while modifier is active to prevent double-fire.
  • 32X (PicoDrive, GCGamepad): New GCGamepad mapping section — A/B/C/X/Y/Z mapped to face+shoulder buttons; hold L1+R1 combo adds Start (mod+A) and Mode (mod+B).
  • GameCube (Dolphin): R3 (right thumbstick press) maps to GC Z button; additionally, holding both triggers simultaneously in GC mode also fires BUTTON_Z, with trigger axes suppressed during the combo.
  • Jaguar (RetroArch): Numpad buttons 1–4 mapped to L3/R3/buttonOptions/buttonHome on the touch controller; 5–9 and 0 are no-ops pending additional RetroArch core support.
