ColecoVision 31-in-1 Flash Cartridge
Version : 24/03/2013 - FIX 3

This board is made to store 31 rom files into a single Flash or UVPROM (1M x 8 bits).
To use it, you need a specific 'bootloader' stored at the bank 0 location (first 32k bytes).
All other rom images must be stored into the other 32K bytes banks.

Running the bootloader lets you choose a rom image (between 31 images), switches to the corresponding memory bank and launches the image.
