Issue with Me and My Katamari PSP extraction. HELP

So, I just downloaded Me and My Katamari for use on my hacked PSP, and when I extracted the RAR files, all I saw were 50 or so rar part files, but lacked a rar file to click and extract them all to an iso. I clicked on one of the part rar files, kept getting error messages about a broken file or something, and it created an incomplete iso. So, I highlighted all of the files and tried extracting them, everytime got the same error message and more and more incomplete isos. Normally, I can just click on one of the files in the folder and it makes on clean iso, but this is the first time I have come across this issue. I use The Unarchiver program for extraction on the mac btw. Am I doing something wrong or is this a problem with the file itself? PLZ HALP!

EDIT: Also, I tried to make an iso from the entire folder of rar parts, only got corrupted file when I put it on the PSP.

The USA version, right? I just downloaded it to have a look. It's 50 files, with the extensions .001 though .050. Right click on the 001 file, and tell 7zip to extract from it. Don't use Winrar.

Looks like I'll have to go to my windows partition of boot camp. I'll try it on 7zip and see. Thanks for the reply.

It worked, just needed to use 7zip. Never really had problems with The Unarchiver till now. Thanks!

Oh, good thing you got that sorted out. I totally didn't notice you were trying to extract on a Mac :sweat:

Just to throw it out there. On a Mac you might be able to recombine the file with HjSplit (I think there's a Mac version), and tack on a 7z extension. Then it may work without having to use Windows. May, not sure, I don't use Macs.
