Console 64

This simple project is supposed to expose an emulation of the Commodore 64 in a UNIX console, just for the lolz.

Status

Simple BASIC commands should work. LOAD / SAVE functionality is implemented.

List the current working directory using LOAD"$" then LIST.

Docs

A bit of C64 documentation can be found in the docs/ directory. The annotated ROM disassembly is particularly useful. Thanks Marko Makela!
