I signed up just because of my issues of this game.
I was originally using the patch in this topic and it worked perfectly as soon as I tried it and I was able to play almost the entire game without a crash or problem.
However, I've gotten to Day 357, after fighting the boss, there's my problem. I begin watching the cutscene and shortly into it, it becomes stuck in a loop for the video. The VA stops, but the background music continues to play.
I'm curious if anyone else has experienced this, or if they've gotten past this point. I'm using my old original R4 with 1.18, if that helps. I'm tempted to just get a CycloDS soon, as it always seems to have no issues with this stuff. Or an Acekard 2, as it's a lot cheaper and seems to do everything fine as well.
EDIT: I decided to try out getting YSmenu since some people have said that it worked for them. Once that was all figured out, I just tried the clean copy of the game again and it worked fine.
