I looked through this forum and the ewin forums, but couldn't find anything similar to my problem (and reading through several other freezing/hanging threads didn't seem to help). I've got a DSTT with the GBA & Explorer 2in1 pack. I'm running v1.08 of the DSTT Kernel and v1.06 of the GBA loader. I tried both a 4GB microSDHC and a 1GB microSD card. The GBA loader runs fine. All the roms I've got in there will run fine for a while, and then the next time I try to load ANY of them, I get the white screen with the "Game Boy" animated logo, and then EVERY SINGLE GAME will hang/freeze on that. Formatting/reloading the card doesn't work. Deleting the EWIN patch/sav directory doesn't work. Going from FAT16 to/from FAT32 doesn't work. Changing from the 4GB card to the 1GB worked once, and then the 1GB card started doing the same thing. Any suggestions on what to try next? I really love my GBA games.
