<forumuser name="Glitch" /> Glitch (real name Mark) is a UK-based scener, and a Tech Member on the Sonic Retro forums. He specializes in Z80 assembly, and has made a disassembly of Sonic the Hedgehog 2 for the Sega Master System. He has made various breakthroughs in Sonic 2 SMS hacking, ranging from implementing the Spin Dash into the game to swapping level slots around; for example, Green Hills Zone was moved to the slot for Under Ground Zone. He has also ported Sonic Triple Trouble to the Sega Master System.
While he doesn't have any major involvement in the Sonic scene as a whole, he has done numerous amounts of technical work for Sonic 2 LD, a collaborative effort headed by Dr. Eggfan to downport the Mega Drive version of Sonic the Hedgehog 2 to its 8-bit counterpart.
While he is rather new to the scene, Glitch shows great promise with his technical prowess. Any work he has been involved in prior to his entry to the scene is not currently known of, but it is expected that it involves programming in general to some extent.
