As promised in the title, GBA Exploader v0.57 locks up completely when I run it from my R4DS at the blue-bordered PSRAM Mode screen. There is no response whatsoever no matter what I press. In addition, the directory list on the top screen appears blank. It was running just fine last night when I first used it to write Mother 3 to my EZ Flash 3-in-1 expansion pack, but it seems to have given up on me overnight. Incidentally, I can run the game on the 3-in-1 hassle-free if I eject my R4DS and choose 'Start GBA game' from the vanilla DS menu. Essentially my 3-in-1 seems to be stuck as a fully functional Mother 3 cartridge. I have no way of accessing Exploader to write any other ROMs to memory (I even tried an old version of 3-in-1 tools). I imagine there are worse fates, since I'm not having any save problems, but I was planning on using this thing to play other games. If it makes any difference, I did write a Final Fantasy VI Advance ROM to PSRAM to make sure it was working, and I encountered no problems. Also, I received the 3-in-1 with a Super Mario Advance save already in PSRAM, presumably because the retailer tested it before it was mailed to me. This is my second 3-in-1. Any insight? edit: Oh yeah, I suppose it's worth mentioning that I do get the 'no slot 2 device found' prompt if I remove the 3-in-1 altogether, and pressing A from there shuts off the DS like it's supposed to.
