<forumuser name="STHX" /> STHX is an Italian scener, and one of the most recent sceners to appear on the Sonic Retro forums.
He discovered almost by chance the Sonic scene and the Rom Hacking world while looking for the hack Knuckles the Echidna in Sonic the Hedgehog. After a few months spent learning the basics of ASM programming he finally decided to join.
His first work for the scene is the Fix the Level Select menu in Sonic 1 guide, a simple guide which also aims to help the new less experienced hackers (like himself) to get a better understanding on how the Sonic games handle their own stages.
His current project is the hack Sonic The Hedgehog in Mushroom Kingdom (or simply Sonic in Mushroom Kingdom), which aims to be a reinterpretation and adaptation of concepts, levels and enemies taken from the Mario universe to make them fit in a Sonic game.
