Worked fine for me with Debit / Credit card.
Bought Pinball Dreams and Little Weezard, both really good games. I had trouble getting LW on the machine, but I think that was my home PC (WinME) cutting the USB connection to the GP32, but installed it at work no problemo.
Might have to bite the bullet and go for XP or 2000......hmmm.....
Might get a new Hard Drive first though just in case!!
