Ok, Here is the problem. First I'm on system menu 4.2u, latest version of cioscorp. Now, I updated ios 56 to the latest version with DOP-IOS so I could play mega man 10, and it works perfect. But now I cannot play Guitar Hero 5, it shows up in the disc channel, but when I try to play it gives a 002 error, or sometimes it says there was an error and to shut off my wii. So doing some searching everyone seems to say to get it to work I need IOS56 v5146 with rev14 DIP. Ok, so I got that and I can get it to play, but it breaks mega man 10. Mega man 10 throws the 002 error. So I reinstalled the latest IOS56 again, and now mega man 10 works again. Is there any way to get both games to work together without throwing out errors, and breaking one in the process?? Also, I'm not using USB loading, I tried that and my HD got corrupted and I haven't had time to reinstall all the games, so I'm using some of the discs I actually had made. If anyone can help with this problem I'd appreciate it.
