I am not a coder myself but I learned from BgK that VBA-M is now not very clear in abstraction as the core and frontend is not separate from each other. By having a clear abstraction model, the core can be developed into libvbam upon which the frontend (GUI, console, etc) can be built. This gives flexibility in porting vbam to other platform.

Qt,GTK,SDL,etc <---> libvam

Well, with the Qt4 GUI, there is a effort towards a abstraction layer between the core and the GUI.

I reckon though, it needs to be something like libgambatte to make things simpler.

So overall, I agree. Its something that should be looked at.
