Cheers for your reply.

I need to test this again properly; I noticed that the TOS i used was the one that came with the mac emulator, which is actually  EmuTos, which im not sure is whats causing it not to work. I´ll have to have a google around and see if i can find a proper TOS dump. Just to give you a little idea of what is happening/not happening: the emulator loads, showing the neoflash background, if i press R, the upper screen goes green and below shows the autostart rom screen, I select Rick Dangerous, press A, the top screen then goes all funky, the only way i can describe it is color noise. on the bottom screen the % counter and numbers fluctuate. For example, right now says 98%  5  12512

Hope this gives some insight.

PS: the app itself still works, ie i can press keys on the keyboard and get back into the menus.
