 USB Adapter Compatibility
I'm looking to play some beatmania simulators on my computer, so I want to buy a USB adapter. My question is, will any adapter work? I know not every kind will work with dancing games, but I didn't know if it was the same for beatmania. I tried searching for the answer, but all I could find were threads on lag. I was hoping I wouldn't have to order one online, because I seen one at the store for $10...but I didn't want to waste the money and not have it work. |
