For the .iso cd games i've had to rename the file name inside the cue to make it correspond to the filename because it wasnt launching, seems to be case sensitive.
I've tested all of my cd games, they all work very good (aspect ratio & fps), maybe the shooters are showing a little bit of slows here and there (especially on Star Parodia, goes down to 49 fps but still very playable) but for Loom that is in .bin format ( rom), its launching but there is a problem with the aspect ratio (again, yeah !!!), the picture is slightly shifted on the right and when i press Start + X, i get the whole picture but then it becomes blurry, here are some pictures :
