I just noticed...all my other plugins are named cheat.plg, yet the Gen one is MH_Generation.plg and the one from that link is speedfly.plg.
Do I rename it back to cheat?
I've placed the plugin in the folder.
Then I use the ntrswitcher and use 3.4.
The game actually boots this time but it crashes when trying to load the save.
Maybe I could try renaming one of the new files to ntr.bin and try with the old app?
The Monster Hunter Gen plugin doesn't seem to work, after starting NTR and then starting the game, it just hangs on the Nintendo 3DS screen and loads forever.
