Sonic 3 Delta, is a rom hack of Sonic the Hedgehog 3 alone, that allows further access to the zones from Sonic and Knuckles.

Gameplay Edit

Outside of the extra zones added, the gameplay is exactly the same as the normal Sonic 3, although there is an options menu (the unused Sonic 2 Options Menu in the coding), replacing the competition setting from the normal game.

Sonic and Knuckles Zones Edit

While access to them has been increased a bit, the difference from access to them before, is that in the Sonic 3 alone, accessing them (except for flying battery) would cause the game to crash. Sonic 3 Delta allows access to the level themselves, although, the levels themselves are partly broken.

Flying Battery ZoneEdit

Act 1 Edit

  • Due to the speed booster not being present in the first part of the level, it'll require a fully charged spindash near the ramp in order to make it up the first part.

  • If using Gens (not confirmed for other emulators), then after you beat the boss of Flying Battery Act 1, and end up in "Act 2", part of the Act 2 music will play very off-key in the first part that plays in the tune (and does so in all of the loop).
