Game cartridges are inserted at the top and contain an EEPROM chip that can be written with a special programmer. The console itself is also housed in a printed enclosure with a design reminiscent of the Nintendo 64. The buttons are implemented with Cherry MX Clear switches - an unusual choice for a gamepad perhaps, but they’re apparently very comfortable for long gaming sessions.

He also made his own controller, a 3D printed one with four directional buttons, three action buttons and a start button. The video card comes with DMA for fast transfers and even includes a blitter, which enables it to move images around the screen quickly without loading the CPU.įor the controllers, decided to go for the more-or-less industry standard DE-9 connector gamepads as used on the Sega Genesis and various Atari consoles.

Composite video is generated by a clever circuit made out of discrete logic chips. The main CPU is a WD65C02 running at 3.5 MHz, assisted by a 6522 I/O controller and 32 kB of RAM. The GameTank was designed to be easy to build by anyone, and is therefore largely constructed from DIP chips that can be bought new at any component distributor. Today we can even show you an entirely new 6502-based game console: the GameTank, designed and built by. And while the 6502 has been pretty much obsolete since the mid-’90s, that hasn’t stopped hackers from building new systems with it in the 21st century. The NES, Atari 2600, the Apple II, the Commodore 64 and the TurboGrafx-16 are just some of the many game consoles and home computers built around the 6502 CPU.
