ya i had a Bonk card do that...
I might as well show my glitched hucard that is a Arcade Duo card. I cleaned the Duo card a bunch of times and tried it on multiple systems(SCD, Duo R, PCE Duo) with the same results. I don't have too many Arcade games....Mad Stalker freezes at the beginning level and the Sapphire bootleg has glitches and freezes after beating the first level. It's not the game discs either since I loaded them with a Arcade Pro card on the same three systems and they works perfectly. Super CD and regular CD games seem to work perfectly with the Duo card. Here's some glitched screens shots of Sapphire. Most enemies are white blocks. The second screen shows the background blanked out when using a bomb.
