Just for information: Re-Dumped Overkill using the USB Loader und now it runs just smooth, so my problems before really were because of a bad dump I think.
Dumped and Linux-copied several different games now, getting the following experiences:
- Dumping via USB-Loader of original DVD runs well in 4 of 5 cases. In the fifth case, dumping gets stucked, giving me an exception when trying to shut down my wii. Just trying it again fixed it in all cases by now.
- Dumped original DVDs (if not got stucked) run fine in all cases. Didn't play that much, just loading a savegame and looking around etc., but seems to be no problem here.
- Dumping from burned backup DVDs runs well in 1 out of 5 cases. The dumping itself runs well without problem in all cases by now, but when trying to start one of these four out of five games, it crashes with a black/white screen or just freezes. Using Backup Launcher Gamma, all of these games run without problem, so dumping seems to be fast, but a little insecure with Backups (which is okay for me).
- Linux-copying ISOs to WBFS ran flawless in all cases but one. When I tried to copy over Shaun White, there weren't any error and the ls command showed, that the game was really there. But Wii wasn't able to find it. Re-copying fixed that issue though.
