So, the emulator I tried that I contacted the guy who made it? It seems to be working! Going to try GenericShep up through the walkthrough to be sure, but it seems to be functioning. I can't take screenshots in the emulator, but hey, it works, no complaints, right?

Unfortunately, it would seem that it doesn't like the format Wine used for the ME1 playthrough, so I may have to replay Mass Effect. Not a big issue though, as it has more than a few dialogue trees I can take that won't change the endgame save.
