The Sonic Genesis Incident of 2007
one night in 2007, an anonymous person was playing Sonic The Hedgehog on the Sega Genesis, however; after playing act 1 of Green Hill, a "evil demon sonic" comes up and takes the player to a Game Boy Advance port of Sonic The Hedgehog, referred to as "Sonic The Hedgehog Genesis".
the genesis then overclocks and then turns off after 40 seconds of the 1st level of Green Hill. (because the genesis is 16 bit and the gba is 32 bit)
