The C64 Direct-to-TV, called C64DTV for short, is a single-chip implementation of the Commodore 64 computer, contained in a joystick with 30 built-in games ().
The joystick can be bought at Conrad (but I've also seen it at Zielpunkt) for ~25 Euros.
This is an amazing piece of hardware, but comes with a few weaknesses:
- Only 1 joystick, no support for two-player games
- Only a limited selection of games
- The quality of the joystick itself is far from the gold standard (Competition Pro)
..so let's remedy this:
The goal is to add ports for two external joysticks, a PS/2 keyboard and a disk drive (1541 compatible).
