It doesn't matter what chip you get, but I'd recommend the Xecuter 2 Lite chip. It's a good chip for a decent price, around $30.00 or so. The other chips are doubled the price but they have more features, but only if you know how to take advantage of it, otherwise go with the Xecuter 2 Lite chip. Softmod will work too. Either way will work as long as you're able to load a new BIOS (X2, X3, Evox M8, etc..) that will allow you to play backups and emulators.
