MultiRom module for an vintage gaming console

We build a MultiRom module for the VC4000 video game console (popular in the late 70s and early 80s) based on a Arduino nano. It loads ROM images from an SD card an writes them via 74HC595 shift registers into an 8k SRAM that is then used by the console as game module.
It works for all 40 games that exists for this console and offers an easy way to add homebrew games.

I love this project! It's such a great idea, to use the arduino in such a way - WOW!
