Super Mario Bros.: an Atari Lynx port from NES disassembly

The Super Mario Bros. Atari Lynx port adapts the NES game's 6502 logic to the Lynx 65C02 using a complete disassembly. Adapter code maps NES tile rendering to Suzy sprites, APU output to Mikey audio, and controller input to the Lynx joypad; artwork and level data are extracted from the user's ROM at build time.
