Neo4all/aes Or Mvs? Chui And/or Fox68k Or Anybody, Help!

What's happening?? Is it only with me? Man, it runs MVS for me!! Whats this? I can only use 3 buttons (A,B,X), the Y button is useless... the only thing it does is pausing the emulation as long as i hold it down!?!!? I dont have a single idea of whats going on... The only thing i can suspect is the SBI program (that one we use to put lots of apps, demos emus on the same cd.. you know what im talking about) but i dont think it is causing the problem.
