IDK about anyone else, but I had trouble getting the mouse to work. Everytime I clicked inside of the VM, nothing happened. When I switched the VM to fullscreen (CTRL+SHIFT+F), and returned to normal (Escape), it suddenly worked. IDK what that was about, but if anyone else has that problem, try my solution. Also, you need Chrome to run the emulator, as Portable Native Client technology isn't supported in other browsers. I also had problems running certain programs, the VM would sometimes either freeze or reboot itself. Other times, the window would just exit as soon as it started, no error messages. I don't know much about Amiga, but I do know how sad it is to see an Amiga VM that can't even run the Boing demo. After all, Boing is considered symbolic among Amiga users.
