It doesn't implement a full VIC-II core (like the Chameleon or > Ultimate64), but snoops the bus to know when to display sprite or bitmap > data, and it watches register writes to know the internal state.

(and you can see it does all that in the vhdl code) it'd be very interesting how well it works though, and if it can deal with all the fancy things used in demos :) -- http://hitmen.eu http://ar.pokefinder.org http://vice-emu.sourceforge.net http://magicdisk.untergrund.net If you can't beat them, join them.
