Some people said in another topic that the crashes also vary on the dump.
I have a Kingston jap formatted FAT16, 64k, and it crashed in the first time I opened the menu. Then I started the DS again, started the game in R4, and it didn't crash anymore for the few minutes I have played after that, yet I'm afraid I will experience it again since it already happened once.
So for the people out there who have a Kingston jap formatted FAT16, 64k, and have been running it successfully with no crashes, I would like a tip of which dump are you using from the game. Thank you
