The 31-in-1 is a multicart board for the ColecoVision (SMD).
It is made to handle 31 rom files stored in a single UVPROM.
The UVPROM (IC3) should contain 31 images (32KB max) and the specific loader.
Running the bootloader lets you choose a rom image between 31 images, switches to the corresponding memory bank and launches the image.
Usage
Concatenate 31 image files (32KB max) then the loader to get a 1M byte file then burn it to the IC3 chip.
Plug the cartridge in the dedicated slot. Components MUST be in front of you !
Power-on the console.

Many thanks to my friend ZX (http://zx81.zx81.free.fr) for his help and his very great bootloader !
A simple application has been developed to easily create your ROM files. It is available here
