==The Manic Rumor==
There were many rumors of Manic being a playable character with many screenshots that had supposed evidence. The rumor first started in the EGM gaming magazine with the cheat being shown in reverse "MGE- neercs tceles retcarahc eht no eb dluohs cinaM dna soahC sa emag eht etelpmoc neht RIM.LAERSICINAM otni TYP.23908M dellac elif a emaner dna retcarahc elgnis yreve sa emag eht etelpmoc ot deen uoy tsriF ...kcolnu ot ysae ton si eh tub emag eht ni tsixe seod cinaM" and it translates to "Manic does exist in the game but he is not easy to unlock... First you need to complete the game as every single character and rename a file called M80932.PYT into MANICISREAL.MIR then complete the game as Chaos and Manic should be on the character select screen -EGM" However the code did not work and many people were disapointed. There is still many more info to be told.
More to come.
