WHEN SWITCHING OPEN MANAGERS YOU WILL NOT LOSE ANY GAMES DOWNLOADED!!! They will be visable in all managers.
1. Open manager 2.1 have the option to copy BR disc
2. Gaia has a HIGH success rate of backing up games (recommended)
3. Multimanager v1.09 is by far a superior back up manager and will upgrade iso file 3.50 to 3.41 automatically when you launch a 3.50 game. It also has a file manager included (recommended also) But please not that many more steps are involved to play a 3.50 version game but that option gives you a head start. I run all three of these myself for various reasons, like them a lot.
P.S. man you need to upgrade from that frist OPM you won't know what to do with yourself!
Hope this helps, GOOD luck and feel free to ask any question and I'll try to help.
And if I deserve it? Please +rep me!
