Amp, What's Up Doc?

An all-new romhack of the Bugs Bunny Crazy Castle has been released. This romhack includes two patches, a graphics update and a new set of 64 levels.
Each Looney Tunes character has been edited to resemble his animated counterpart. For example, Sylvester’s fur is black and his nose is now red. The other Sylvesters in the game are now black with different nose colors. In addition to the characters being changed, the pallets of the level backgrounds have been changed to make a more brighter and colorful gaming experience. The graphics patch is compatible with other level romhacks, including Frank Maggiore’s Ultimate Crazy Castles.
The Level set provides a difficult, but not impossible challenge. Each level has been tested to ensure that no level is too difficult. While no level is impossible, there are several levels that require a little more thinking and strategy. The level patch is compatible with other graphic romhacks.
