Did you try turning the code off?
Game events will occur normally when you deactivate the code. Depending on the one you happen to be using, L+A will turn it off(if not that A+B. I forget easily).
The problem with the Liberty Ticket codes seem to be that it doesn't work with Action Replay DSi.
Is there anybody thinking about/in the process of making one that works for newer action replays?
AR and AR Dsi, both fully updated. It just gives me a white screen when I enter it, and the normal AR doesn't have a code manager, so it would suck to have to re-enter it. As of right now, neither works.
