Do you have the ISO's of both discs? If you are using DMToolbox when you convert the second disc it should automatically name it 'disc2' (if not re-name it yourself). Just put that converted/renamed ISO into the same folder (the folder named by the GAME ID) with the first disc ISO (the one named 'game') and it should work.
Yeah, I'm ripping from my original retail game discs, and this was the exact method I've been using so far, I just wanted to do it directly from the loader to avoid constant plugging-unplugging of my hdd. I think it's damaged by now, lucky I had a spare
I have been using a Fujitsu MHZBO808H (actually, the stock hdd of my PS3), 80GB, FAT 32 formatted, 32K cluster, etc. No problems so far with loading and running games. I can install game disc 1 perfectly, then insert disc 2, choose Install, press A and the error message inmediatly shows up. Here's the screen, I've just tried using 70r69It should be working.
What drive are you installing to?
How is it formatted?
At what point are you getting the error?
What is the exact text of the error? "Error = Ret" dosent appearar anywhare in the code.
