I am just having a look at their website, when they have their releases saying the following
Notable changes since 1.28.0-UNSTABLE:
I would not even use the thing, when they are saying that the previous version is unstable, there are better emulators out there to do what you need to do.
Obviously you do not use a Z drive, I mean come on, no one uses a Z drive do they?
If the program is marked as unstable, it could be an emulator problem and not that of AM.
