It includes some ASM Games. After it has loaded, press Custom> F1 to get to the gamemenu.

Obtain a TI-85 rom:

Get a TI-85 calculator. Make or get linking cable (serial or parallel should work).

Download a rom dumper. Virtual TI (Windows) and TiLP (crossplatform) can both do this.

Follow instructions provided with rom dumper.

Use fixrom if you experienced corrupted ROM files, see the included README.fixrom (optional).
