[PS2] USB Flash Drive for Save Backups

Alright, I have my PS2 with a Slide Card and Swap Magic 3.8 + Coder... I've been trying to figure out the best way to copy my memory card data to my 1 GB USB Flashdrive and therefore help clear up space on my memory card so I can save some games again (I'm no where close to beating Fatal Frame to get back my 1,800 KBs of space its eating up).

I've heard about booting ulaunchELF (which I cannot seem to find anywhere... I think its up to v. 3.55) from either a CD or the USB drive itself using Swap Magic. Does it have a transfering program built in to copy from the memory card to the USB flashdrive and vice versa? If I could get this to work, I think it would work best... but I am very ignorant about such stuff still and haven't even been able to find it anywhere to test it.

The other way I've read is to use Action Replay MAX EVO (which I'm downloading now, but I'll have to burn it myself since I don't have much money after just getting Swap Magic and the slide card with replacement cover, heh). This would work, but I've heard a lot of horror stories of loosing all saves, copying the data and then becoming corrupted/unable to uncompress, or only copying parts of the memory card... I'd really hate for this to happen (wouldn't we all?)... as keeping these saves is the main reason I wanted to copy them elsewhere to begin with. Maybe there a specific way to avoid the data loss?

I think it would also be fun to mess with the Save Builder utility and/or downloading saves off the internet... but this is less important...

Thank you for any help. I'd test out the MAX EVO route when it finishes... but I'm too much of a coward.

Jam it back in, in the dark.
