a copy of jet grind radio broke my dc, help!
 

ever since i started playing a US copy of jet grind on my pal dc its been reseting randomly, ..i passed the copy on to someone else and his has started doing the same. can anyone help!?

i think its this cos its never happened before and im thinking forcing a game to run @ 60hz on a pal dc (without selecting it like pal games) has hurt it
