Sonic Delta

Sonic Delta Reloaded is a groundbreaking ROM hack by famed Sonic scene member Esrael Neto, which combines Sonic the Hedgehog, Sonic the Hedgehog 2, and Sonic the Hedgehog 3 & Knuckles with several prototype elements restored.

The main version of this hack was formerly titled Sonic 2 Delta and was based upon the Simon Wai prototype; version 0.24 transferred the codebase to ‘revision 2’ of Sonic 2 from Sonic Compilation, and version 0.29 moved to the Sonic the Hedgehog 3 & Knuckles codebase, shortly followed by a name change to Sonic Delta 40 Mb.
