Hey guys,
I initially couldn't get Harvey Birdman, and Star Wars: The Force Unleashed (both WiiBrickBlocker patched and unpatched copies) to work and would always get the dreaded "An error has occurred" message. So after much snooping and tinkering, I've gotten both to work, and relatively easily. Below are my instructions. Sorry if any of it's redundant. It worked, regardless.
My specs: System 3.3u (using downgrade), Mose's custom Backup Launcher WAD based off WiiGator's BL 0.3 Gamma, WAD Manager Channel 1.3, Homebrew Channel 1.0.1, Twilight Hack 0.1 beta 1
1. I went to Wanikoko's blog, and downloaded both the cMIOS Installer (rev 03) and IOS36 rev 7 installers.
2. I googled (yes kids, its your friend, use it) both RVL-mios-v8.wad and IOS36-64-v1042.wad and downloaded both.
3. I renamed the cIOS36_rev7-Installer.dol and cMIOS_rev3-Installer.dol to boot.dol and put each in a separate folder in the /apps directory of the SD card
4. I put both WADs in the /wad folder, and installed each via WAD Manager.
5. I installed both cMIOS and IOS36 via Homebrew Channel using network install,
6. I launched both patched and unpatched copies of each game, crossed my fingers, and both worked perfectly.
Both games run at 99%, no audio sync errors, VERY little slowdown if any of FMVs and no crashes. I imagine this method WILL work for a number of other games that are currently giving the dreaded "An error has occurred" message. I will be trying other supposedly "nonworking" games soon, and see if they will now run.
Give it a try. Even if you think you have it installed..it can't hurt to reinstall both the WADs and use the custom installers and try again.
UPDATE: I originally couldn't get Call of Duty 3 to run either, it would always give the same "An error has occurred" message when the game tried loading the actual ingame graphics, so I tossed the disc in the coaster pile. I decided to dig it out, try it and it now works as well.
