Pretty much everything it features is broken: most of the music ports from Sonic 2 and Sonic 3 & Knuckles (which don’t fit at all) will play static noise (just like the SEGA sound), and there is a brand new version of the spike bug which teleports you to location 0000 0000 and hangs up the game.

Only Green Hill Zone 3 is playable in this hack, even by using the level select; however, if you don’t press any key at the title screen, you’ll see that the demos that take place in SYZ1 and in MZ1 will play just fine.

Megamix is garbaged compared to this masterpiece!

By the words of Yago himself, the level layout for GHZ3 is “made up entirely of 5 chunks”; some tiles are also broken and/or invisible (this is the case for the boss arena, which is below the viewable area). The sprites and the art are “incredible quickly rendered MS-Paint colorful graphics”.

If you use Debug and Level Select, go to Special Stage, collect an emerald, and you will go to glitched Green Hill Zone. Use debug to pass it. After that, you will go to Act 2. As of today, it is no mistake to believe that this is the best hack of all times.
