So far on the MB, we have Toei, Modern, SRBii, 2 FSonics, SMS, XSonic, Alt Sonic, SSNSonic HD, Werehog, Almost Super, EarlessRE, Mecha, Flare/FSonic, Neo, Hard, Earless, Early, SSNMetSon, and Hand Drawn
So, as pointed out by Hisashi Eguchi himself, it turns out the CD opening design for Sonic is not actually Toei's design, but instead it was made by Junio Studio. And due to his resquest and out of respect to the original creators, Toei Sonic has now been renamed to Junio Sonic... I know, hard to believe it wasn't actually Toei all this time.
Rename aside, v1.1 is out, and it got some massive changes, once again thanks to MotdSpork for the great work. In case you felt like the bullet dash slowed you down too much... well, the ability has been tweaked a tad to keep the fast flow of the rest of Junio Sonic's gameplay. Not to mention the inclusion of free aim as a console command, for those who prefer aiming with the mouse, and... well, super running frames, for the ones who like making everything super.
