This is my game copier collection page.
If you don't know, these devices were used to copy game cartridges to floppy disk or transfer to pc via parallel. Most of these were made for the Super Nintendo, but a few were made for Sega Genesis and a few other consoles.
The sidebar lists all the copiers I have in my collection and if you are interested in researching more into this topic, the Tototek forums are your best bet.
