I don't know what category should I post this but I use an R4i so I guess this goes here. I recently upgraded from 2gb kingston microsd to 4g kingston microsd. So I copied everything to my 4gb (firmware, games and saves). The problem is, ALL of the saves on my 4gb became corrupted. I think the problem is on the micro sd. I need advice on how to format it like: should I use FAT or FAT32 the allocation unit size what formatter to use etc. I use Wood R4ids 1.20 from this site.
