However, due to Sonic's palette having been updated, the coloration is glitchy. The only badnik whose graphics remain intact is the Piranha.The Sonic 1-style springs are present here, whereas the other Zones in this build use the Sonic 2 style.Crabmeat has unused art from Sonic 1 in his sprite.Related to this, all Sonic 1-Up monitors are Tails 1-Up monitors.All three Acts have different monitors than Sonic 1, showing that the pointers for the monitor types were changed early in development.Act 3's boss' camera lock is 160 pixels to the left of its usual spot.Unfortunately, this is also one of the main reasons the object art is broken. For example, the level's tilemaps have been changed from 256×256 to 128×128, and the art has been updated to look correct in 2-Player mode. All of the necessary data for Green Hill is still present, and has even been updated to use Sonic 2's data formats.Using these, it plays perfectly beside the broken art. The original collision array data from Sonic 1 is present in the ROM, and can be restored with a set of Game Genie codes: AA1A-CEAL AA1A-CEFT AA2A-CEB0 AA2A-CEB6 AA0T-CAG6 AA1A-CAEC AA1T-CAA2 AA1T-CAF8 AA2A-CADJ AA2A-CADR AA1T-DECG AA1T-DEHN AA2A-DECN.The S-bend tubes are broken as well, with the engine treating most of them as invisible barriers.Because of the different collision array, most slopes make Sonic fall out of the level and die.As you'd expect, it's Green Hill from Sonic 1.except now with broken collision and glitched/missing graphics.
