VIC-20 Emulator in TIC-80! (W.I.P)
This is more a demo than an actual emulator. Emulates only: keyboard (not fully), screen (with cursor and without color RAM, only default colors and some border code) - no any chip emulation is present yet.
Keyboard emulating is not fully finished! You cannot break from RUN command, you have to reset the machine by pressing ` key.
How I said this is more a demo than an emulator. Beware bugs!
