Is this some normal function you can access when you download a Commodore 64 game through Virtual Console? Or have I stumbled on something?
I bought Impossible Mission through Virtual Console, was playing it with a friend, when it crashed out to a BASIC interface. With the click of a button, an on-screen C64 keyboard appears, and we can type and run BASIC commands (We tried just a couple - I know nothing about this; my friend knows a little).
Now, every time I quit to the Wii menu and load Impossible Mission, I just get the BASIC entry screen:

I know of one Homebrew Wii C64 Emulator, but what I have on my screen is a little different.
