Backing up PSX save files on PS2 and converting them?

[morrisk]

Hi,

Not sure if I'm posting this to the correct place, but I need help pulling some savefiles from my (official) PSX memory card. I've tried doing it on my PS2 with uLaunchElf, which let me copy the files to my USB stick but when I access them on my PC they have no file extension. How do I convert them?? (want to use them on my PS Vita)

you need to convert them to psu, then convert them with memory card rex or similar program. unlike psx saves, ps2 use a file system, so they can't be raw, which I think you transferred them as.

If they don't have a file extension, you can simply rename the file and give it one, if the converter/program you're using on the computer cannot find the file

unlike psx saves, ps2 use a file system...

these are ps1 saves, but on a ps2 - so should be fine

oh, I misunderstood. psx is raw, yes. you can usually convert them by making a save in the memory card, which is usually what emulators and stuff use via a hex editor. all psx saves start with SC so search for it, then inject them with a length of 0x2000/block. very easy to do.

psx saves shouldn't have an extension, but most apps use memory cards instead of individual saves. he can create a new save in the game, then hex paste write over the new save with his own.

I managed to do it with this program. Only program I could find that would convert a raw file.

that's the format I was thinking of. mcs is a type of memory card image. it does the same thing as the hex method. each block starts with SC in the ascii portion in hex, then goes down 0x2000 in length. that's how I got a save from my ps2 to work with the psx classic. I just made a new save and overwrote it. not much more difficult. the reason is the first block is actually a toc with save information. there's no file names mentioned in the actual saves, which account for the next 15 blocks, so a psx memory card is actually 16 blocks of 8KBs each equaling 128KBs iirc.

btw, could you upload the save. I found my psp saves, but I didn't play psx on the psp whatsoever. I was going to see if they're indeed compatible with the hexing method. they seem to contain a header like a lot of these formats do to make it 1KB larger.

I tried uploading, but it wouldn't let me.

Never mind, I just made a .7z archive.

thanks, but I actually meant the psp version to check if you can indeed hex it in.

Ohh, my bad. Don't know if this savefile (It's Gran Turismo 2) even works, because I haven't gotten it to work yet. Can't make a working eboot file of GT2.

yep, it should work with hexing:

it's identical, seems to be 4 blocks, so I did a hex length of 0x8000, since it's 0x2000 per block.
