I'm sorry if this is off topic but this is the best fitting board for my problem. I have an r4itt revolution card for my ds and I'm having trouble getting cheats working. I press rom info and I'm able to find a large list of cheats. I select them and a checkmark appears by their name. When I choose to go save the whole system freezes and I have to restart it. I'll post pictures. If anyone could help me I would greatly appreciate it.
