Version 30/09/2014

Few weeks after making the 256in1 cartridge, my friend ZX81 & I have decided to do something better.
We have made a new cartridge, containing up to 255 (Atari 2600) games or homebrews.
Instead of using micro-switches to select the rom image, a bootloader and associated electronics have been added.
The user power-up the console, highlights the game with the joystick and press fire to launch the game.

Usage and restrictions
----------------------
* This cartridge can handle 2KB and 4KB rom images only (Not banked).
* Only Atari 2600 rom images are supported.
* The board can be plugged-in Atari Jr and Atari 7800.
* Due to the form factor, the cartridge can not be inserted into the Atari 2600 slot without modification.
* Bootloader must be inserted at the beginning of the ROM.
