Cramming Solitaire onto a Nintendo E-Reader card

The author recently finished creating Solitaire for the Nintendo E-Reader, fitting it onto a single card. The E-Reader is a Game Boy Advance peripheral released by Nintendo in 2002. The E-Reader can load mini-games, extra levels, animations, and more by scanning dot code strip cards. The author’s journey into making games for the E-Reader is documented, notably exploring z80 assembly for creating applications due to smaller resulting binaries. Developing tools and debugging challenges are discussed. The E-Reader-Debugger project in VS Code allows for debugging and exploring ERAPI API functions, offering a powerful developer experience on this nostalgic platform.
