Cant see what you guys are arguing about really.
Floppy based copiers are obscure, so are transfering roms from your computer to the backup unit IMHO.
That Tototek flash-cart might seem great at first, but look closer. Only hold up to 4 games. Needs a printerport and USB at the same time for flashing. I bet you need to erase the card completely whenever you want to flash it again.
In a perfect world it would be able to hold a memory card of 4 GB with a slick menu system, but its not. Its rubbish.
