Chip McCallahan in Sonic the Hedgehog 2 is a Sonic 2 hack created by MainMemory. It replaces Sonic the Hedgehog and Tails with Chip McCallahan, the main character in Chip's Challenge. Chip can't run fast, roll or jump high, and rings do not protect him from damage. When you die, you will get one of the death messagesfrom Chip's Challenge, and the level will restart with no decrease in your life count.

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).
