So to play your game, I used my Everdrive from Krikzz, you put a micro SD card in it that contains the games, and off you go.
On the other hand I also have a "dumper" which allows you to flash a blank cartridge from the rom on the computer, it's a good solution for example to market your game. If you want a copy of your game one day, I can flash one for you (I've already done it for several developers), but I'm in France, so with the shipping costs, it may not be the ideal solution ;) Where are you from ?
