need a patch for the game. im not going to update my r4 cause i have had to much trouble with that already.
What!? You're not gonna update? Too much trouble? That's bullsh*t. It's very easy to update. I made a tutorial, it's here: http://forum.romulation.net/index.php?topic=40353.0
There are alternative patches to modify the ROM to fix the AP. http://filetrip.net/f3415-Chrono-Trigger-DS--Copy-Protection-Fix.html should work. I highly suggest you use the Wood R4 firmware however. The (J) version still has AP.
