Hi, I have the usb launcher GX. Last week, I putted some isos in my hard drive. To do it, I took the 4,7 GB isos and I trimmed them with Wiiscrubber 1.4. After, with WBFS manager 3.0, I putted them in the hard drive. I noticed that some games gives me a black screen when I load them (guitar hero world tour, excitebots, animal crossing, sonic unleashed). So, I decided to put the entire iso (not trimmed) in the HDD with WBFS Manager 3.0. By doing that, I learned that the wbfs manager automatically trim the iso (or scrub, whatever ...). After this, the 4 games worked. So, the other isos was, in theory, trimmed 2 times ... I have 41 games on my HDD. Only 4 of them was corrupted. Is there a chance that the other iso (the 37 other games that boot parfectly and seem to work) crash in the middle of the game because they was not correctly scrubbed/trimmed by Wiiscrubber 1.4 ? Thanks a lot ! Sorry for my english, I can't do better !
