Why PyGame

• Python 3 is on Knulli (part of EmulationStation stack)
• PyGame 2.5.2 with SDL 2.32.8 — SDL_MESA/KDG GPU driver works
• Game loop model maps perfectly to TUI + gamepad input
• No cross-compilation needed (unlike Love2D, Rust, or C)
• Rounded rects via border_radius parameter (pygame 2.0+)

Why No PortMaster

• PortMaster’s get_controls adds SDL config that conflicts with Knulli’s ES launcher
• AQUAPING handles controller input via PyGame joystick API directly
• ES shGenerator already sets SDL_GAMECONTROLLERCONFIG
