Make sure the save file matches the rom file name. Also, I have had a lot of bad experience with the saves for all the emulators so far, really recommend just doing the save states if possible.
I prefer running the emulators just for being able to do a save state. That alone makes it worth it. Fast forward on the games it does work on is a big plus as well.
Stack dump when accessing Controller config. Got Suikoden running but had some major issues with the video. Hopefully the WiiSX beta 2 will live up to the hype the teaser is building up.
