GT5 running on kmeaw as well. I had originally ripped it to an external with multiMAN only to find out that it had a 4GB+ file (I forgot to check compatibility lists.) I then used multiMAN to copy GT5 from ext. hdd to internal and it put it back together.
I'm still using Rogero v7.9a as I've had zero issues with any backups. It's a shame that I can't get multiMAN to run backups as all of it's other functions are excellent. When Rogero couldn't find GT5 for example, I used multiMAN to move the BLUS folder from laun12345/gamez to the games folder on the root of the internal hdd. I think I need to clean up the folder hierarchy on my internal to something a little more "standardized" as having toyed with multiple BUMs has created multiple paths... and dead ends. Does anyone with a working version of multiMAN for their backups want to describe their internal hdd folder configuration?
