Super MarioScript: Tools and Tips for NES development
summary
A demo shows a homemade JS-to-6502 compiler that converts JavaScript into 6502 assembly, uses NPM modules and falafel, compiles with NESAsender, and produces a ROM that runs on a writable cartridge. Concrete constraints justify choices: a 1.79 MHz CPU, 2 KB RAM, ~56 usable colors, 8x8 sprites and only 8 sprites per scanline. The build edits palettes and CSV map data, compiles live, and the resulting ROM actually runs and displays the changed graphics.
