I'm sure it's possible, you just need a memory card that can connect to the computer. Don't quote me on this, but I believe there was some sort of Action replay or Datel memory card for the PS1 that was able to be hooked up to the computer... so if something like that existed, you could just put said memory card and the memory card with the save you want into the PS1, transfer the save to the Datel memory card, and then connect the memory card to the PC.
for sure it was DexDrive, not sure about those action replay stuff though.
QUOTE(Kellicros @ Nov 25 2008, 03:14 AM) you can use CWCHEAT to convert your PS1 saves into a most usable PC format (.mcr) which will work on various memorycard tools and PS1 emulators, then you're on your own to find your way to put them on a PS1 memory cards, I know several tools does that, try google'ing.
