[Wii][Experimental Builds] Broken WiiFlow plugin functionality from USB

[Former user]

I have everything on USB, when attempting to launch a game from WiiFlow I get a code dump every time. The emulator works just fine when used from the Homebrew Channel, and using an older build makes it work from WiiFlow so it is definitely the .dol itself and not a problem with the set-up. This bug has been present for a while in the experimental builds.

I have a .dol from 18/7/2020 that works (3501kB), so the bug must have been introduced after that. Sorry if I can't be more specific.

Keep up the good work.

It’s possible this is caused by the version of devkitPPC used to build the dol executable. I think I switched to r34 last summer and it seems there was a bug with argc/argv (which is is used by WiiFlow to launch emulator with loaded game as argument) fixed in r36.

Please try this build compiled with latest devkitPPC (r38) / libogc (2.1.0) / libfat (1.2.0) to see if it works better.

I seem to get the exact same behavior with the build you just posted, code dump when attempting to launch a game from WiiFlow
