From Sonic Retro
Esrael is one of the best hackers that this scene has ever seen. He is well-known for:
- his Delta series of ROM hacks of classic Sonic the Hedgehog games for the Sega Mega Drive / Genesis, most notably Sonic 2 Delta but also Sonic 3 Delta;
- his discovery of lost sprites in Simon Wai’s Sonic 2 beta;
- and his famous level-editing utility, Esrael Sonic Editor.
Sonic 2 DeltaAfter a long absence from activity within the Sonic community, Esrael returned to Sonic Retro’s forums in May of 2012 with a large update to Sonic 2 Delta and contributed many posts including updates to Delta, guides on how to implement many bug-fixes and other additional features for Sonic 2, and the release of his ROM and his disassembly of revision 02 of Sonic 2 from Sonic Classics.
Neto Boot Loader
After another long hiatus, Esrael returned in 2018 to show his latest work, the Neto Boot Loader, a full replacement OS replacing the Firecore OS for both TecToy and AtGames systems that corrects emulation bugs within certain games, the bad sound emulation, and adds SRAM saving support to various games.
