Nope. Still no idea why this isn't working.
My r51 WAD that I had made awhile ago still works perfectly fine, but the r62 (\Root\Softchip\loader.dol) linker channel doesn't work - still code dumps.
EDIT: OK. I've got r64 working thru the linker channel. Don't know if it makes any difference with how I did it, but first I injected r64 into my old WAD, which I installed and launched fine. I changed some settings for the configuration file and then launched the game. All fine. Then I restarted the Wii, launched the loader channel and it doesn't code dump, but my configurations file didn't load the options I had selected before. Is that a problem that's being worked on? Or do I need to update the configuration file from the loader channel to get it to save?
EDIT2: Code dump! r64 worked fine from the linker channel once, but now that I reset the Wii and loaded it again, I'm getting the code dump. What's going on?
