The cable they provide you is boarder-line garbage mass produced junk, and the plastic cheat device feels almost empty. The cheat device is so poorly made, that I noticed that I would have to hold the physical device in a certain way so that my computer recognised it (this is not an issue that only I'm having, read other reviews).
I've had to send this device back to Amazon for a full refund because the "once working" cheat device, began being insanely temperamental to the extent where I would waste minutes disconnecting and connecting the device into my computer until it actually worked. MY ISSUES with this device are: as with most cheat devices, they invest heavily on software, but throw together the cheapest, flimsiest physical crap I've ever seen. There is a back-up feature whereby it stores an exact copy of your current game save, so if anything goes wrong and your cartridge corrupts, you can just restore your old save before you tried to activate a bad or corrupted cheat (in theory). Your save information and selected cheats are uploaded onto Action Replays database, re-coded (adding the cheats you wanted) and resent down into your physical cartridge basically enhancing your exact save, with the new things you requested. You boot this device up and you can select pre-installed cheats which you would like to activate and hit save you cannot add any other codes.
So the way in which this device works is, you start a game save for example (Pokemon X) and progress through the game to a reasonable stage, for example you have seen at least one Pokemon centre and have access to Pokemart items in the first village.
