[move]Just in case you didn't know how to use a game controller with roms....[/move]
??? If your wondering what Im talking about, than read. ???
Some know, but have problems with setting up a gamepad with their emulator. Some dont even know that you can. I dont know all the ones that will work, but the one that I like the most, and I use every time I play ROMs is the Game Elements Gemini with Recoiling Cord.
(You can get it new from your local Wal-Mart for 13-15 $$$
It plugs right into your usb and fires up.
How do you set up a Game Pad on your Emulator? Alot of emulators are different, like ZSNES, you go to game controls under options, and its confusing, so Im not even going to try explaining that one. If you open VisualBoy Advanced you go to Options, than Joypad, than configure and go to 1, (thats the default) When you click on each of the text to ghange the key, just tap the button on the Game Pad and it will change, if it doesnt change hit it a few times till it does. Hope that helped you!.
