These are the Qbert II (Super Qbert) roms sets. 

All that was replaced were the Foreground, background 
and ROM files. Sound roms are the same and the 
game works off of the same exact 8086 emulation.

Do not package roms or distribute them in ANY WAY, SHAPE, OR FORM with
an emulator! Roms are only allowed for download if you
have the actual Qbert II hardware.
