Chris Covell felt like going back to NES coding for a little while to cook up a little replacement ROM for anyone who has the WideBoy peripheral. The WideBoy is also known as "Super Game Boy". This device was available for both, the Super NES and the classic NES (Famicom).
* Runs entirely in NES' RAM ($000-$7FF) for hot-swapping
* Allows full adjustment of the palettes for the GB screen
* Has a screen-recolouring function a la Super Game Boy on SNES http://nesdev.parodius.com/bbs/viewtopic.php?t=5587
