Great Circus Mystery Widerscreen

version 1.1 changelog:

• • fixed crash after losing all lives in 2 player mode

This game, like many multiplatform games of the 90s that appeared on both Genesis and SNES, runs in H32 mode, or 256 pixel width (which is the SNES width). Genesis games can also run in H40, 320 pixel width, and they usually do. This hack makes the game run the gameplay scenes in H40, or 320 pixel width. This took a huge amount of reverse engineering. The things I needed to do were:

• turn ON H40 mode at the beginning of gameplay (injection)

• turn ON H32 mode at the end of gameplay (lost all lives, beat the boss, end of attract mode demo)

• change the tiles to load in earlier when scrolling

• change the sprites to load in earlier when scrolling

Enjoy! bankbank
