Hacks Of Old Sonic Games

In the classic era, Sonic The Hedgehog had four games. People would take 1 or 2 of those games and create alternate versions like: Sonic Megamix, Knuckles In Sonic 1, Sonic 1 With Spindash, Sonic 1 & 2, and Sonic 2 Delta. Here's a development fact: Did you know that Sonic was origionally... MR. NEEDLEMOUSE!?!?!? (Mr. Hedgehog) Here's what he looked like:
Funny, huh? Here's another development fact: Sonic 2 had to go through a lot of prototypes. Sonic 2 Delta brought the thrown out zones, sprites, and badniks back for us to see. This is the prototype of the title screen.
There are other hacks like Sonic Boom, Sonic 1 With Super Sonic, Eggman In Sonic 1, and Sonic 1 Bouncy Edition. If I could make a hack, i could make Sonic Adventure Genesis Edition. You can find these hacks at Sonic Retro. You could find a Genesis emulater at DopeRoms.
