EDIT: Let this thread die. I just noticed....I reformatted my 2gig MicroSD for the R4 to clean up any fragmentation and when I formatted I forgot to set it to FAT. What caught my attention is I had about 50 extra megs of space....because of cluster size differences between FAT and RAW modes, I imagine. Everything seems to be working fine and loading fast, saving too, with it in RAW mode. Now, I have the whole card backed up in the PC, but I'm wondering.....is it safe to leave the card formatted in RAW? It certainly gives me extra space...... Things that are DLDI patched will still work, right? I only have one such file on the card; SNEmulDS and I'm wondering if I should reformat it to put it in FAT or if it's safe to leave it in RAW mode. What say you?
