Sounds interesting, so I gave this a go, and it worked, to my surprise....
However, it crashes 2 minutes later, so, yeah.
Yeah, just spoke to a Dolphin programmer and he told me that the feature isn't fully implemented into Dolphin, so that would certainly explain why it's so wonky, but if this could actually work, it would make testing hacks so much easier! Did you modify the main.dol and if so, could you tell me how you did it?
Yeah, the issue I submitted is here,
https://code.google.com/p/dolphin-emu/issues/detail?id=6732 looks like we need to wait till the Dolphin team fully implements the feature. Ugh.
