The 63-in-1 is a multicart board for the ColecoVision.
It is made to handle 63 rom files stored in two separate UVPROMs.
The first one (IC3) should contain 32 images (32KB max).
The second one (IC5) should contain 31 images (32KB max) and the specific loader.
Running the bootloader lets you choose a rom image between 63 images, switches to the corresponding memory bank and launches the image.
Usage
Concatenate 32 image files (32KB max) to get a 1M byte file then burn it to the IC3 chip.
Concatenate 31 image files (32KB max) then the loader to get a 1M byte file then burn it to the IC5 chip.
Plug the cartridge in the dedicated slot. Components (IC3, SMD,...) 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
