Can't play retail GC discs on softmodded Wii
I own a few Gamecube titles and have never had any luck playing them on my Wii. There have been several threads on this subject on this forum, but none seem to be similar to my case. The various tutorials on the subject did not help. I'd appreciate any assistance :)
My Wii is a Korean model (serial# LKM...) with system menu 4.0U, and was softmodded before I received it. Homebrew Channel is installed, using which I've installed NeoGamma R9 b56, d2x56v7final (249). I don't know if any boot modifier is installed (how do I find out?), and as long as I'm playing Wii titles the unit is capable of playing both backed up and retail discs, as well as via USB or SD with no problems.
When NeoGamma tries to load a GC disc, however, it recognizes the title and starts the loading process as usual, but once it switches to the game's video mode, it gets stuck at a black screen and stays there. At that point all I can do is power cycle. Changing various settings in NeoGamma made no difference. I've also tried other loaders: TinyLoader halts and shows a red bar; SoftChip shows an exception dump screen and halts; the Disc Channel is useless and doesn't recognize any disc, ever, whether Wii or GC, retail or not.
I have performed the steps in the Play GameCube Backups on Your Wii tutorial, including installing MIOSv10, with no results. I've also tried using CleanRip to copy the discs to an SD, then load via DML (either through NeoGamma or WiiFlow) with the same negative results.
Is there anything else I can try?
