Doctor Robotnik's Creature Capture is a hack of Sonic the Hedgehog created by MarkeyJester. It stars Doctor Robotnik with a cameo by Sonic the Hedgehog. The objective of the hack is to play as Doctor Robotnik and try to capture as many creatures as possible by using a net to carry the creature to the creature capsule. Level select is enabled by default and almost all levels are open from the start.

Doctor Robotnik's Plan B is hack based on Sonic the hedgehog made by Painto the hack focused on new boss fights. This one is the same exact version as the last release except one small bug, due to focus on Scorched Quest.Features:* 7 new boss fights - the zones consist only of these, as nobody feels like playing S1 over again with just new bosses. The bosses are using (mostly) original zone boss weapon in more or less direct way, except for SBZ, which originally didn't had a boss.Besides from the main point, I added small little features:* Normal and Time Attack mode - added these after suggestion from my Team, so the game has a bit more replay value. In Normal mode you get 5 lives, while in Time Attack you have infinite amount of these. The progress isn't saved so if you get a Game Over, you need to play it again (Normal mode only, as TA doesn't have Game Overs).

A hack based on Sonic 2 made by Pacguy.The sequel to Robotnik Returns, Robotnik Returns 2 (you can call it RR2 for short). Vastly improved from the previous demo, and mostly hidden from the public, this hack has been in the works for quite some time...Credits: Music: JoenickROS for the music ports, KHinsider for the midis they were based on, and Flamewing for the S3, S&K, and S3D blast ports I stuffed in here and there. And last but not least, Clownacy, for creating the Clone Driver V2, without which this hack would probably have default or horrendously ported music :V Code: MarkeyJester and MainMemory for various fixes and guides, RedHotSonic for his many cool guides, and Selbi, whos' guides offered me realms of understanding, and made things like the custom character moves possible for me to do :3
