SNES9x, FCEU and VBA freeze on rom menu

Hello,

I recently got around to installing HBC etc. on my Wii U. I used the lovely builds that that allow for screenshots of each game and Wii U pro controller support. While browsing the games I find it will crash (just freezes up) from time to time. Not all the time, but enough for it to be a nuisance. I searched the forums and google, but have not been able to find a thread or anything that helps. Any suggestions are greatly appreciated. Is there any other info I should provide that might be helpful?



PS I am also having another slight problem with the screenshots. Certain images show up as grey and glitchy looking. I am using the set of snaps from emumovies. It seems to happen much less often when browsing NES and Game Boy and is more prevalent on more "advanced" systems, SNES and GBA.



Thanks, and sorry if I am being annoying by asking such a vague question.
