I just got a DexDrive, and used both Dexter and PSXGE to transfer my old PS1 saves onto my PC.
Interestingly, I did a binary comparison between what Dexter saved and what PSXGE saved. Some of the saves are exactly the same, but some of the saves have a few bytes that are different. Any idea what might be causing that discrepancy for those saves? I hope it is insignificant, but sometimes a difference in one byte can be very significant.
EDIT: Well I went ahead and also tried the official Dexplorer software. I compared what Dexplorer saved with what Dexter and PSXGE had saved, and the Dexplorer saves were exactly the same as the PSXGE saves (and therefore different from the Dexter saves). So if PSXGE is saving exactly like the official software does, then I'll use it instead of Dexter.
