Also, as an important notice, I am no longer working on the VBA code and I have transitioned it to kxu, who will keep VBA updated and has already created a Linux GTK GUI for VBA. Please be patient with him in and remember that no emulator is perfect.
Why I am quitting VBA? I had to decide what to do and the emulator was taking too much time and effort from me, that I lost interest in it. I have family, work and other stuff to worry about and I think I've done my share of contribution to the emulation scene.
So, help kxu if you can, join the project if you know programming and can help VBA improve.
