ZSNES crashes after loading game (mac)

[crismas]

I downloaded version 1.51 for Mac. After loading it the ROMs seemed to all load just fine initially, then after re-loading upon a second or third time the whole program will crash. It wasn't one specific ROM either, it started out with Link To The Past and then upon loading some others they would randomly work then start to crash. So I'm actually unsure if it's the ROMs or just the program itself. Here's an excerpt of the error code after loading:

I'll be happy to provide any additional info, I just need some help =[

Thanks all!

Is it all or some of the games that are crashing? I'm hazarding a guess that those that are crashing use save data, such as the game you have mentioned.
