http://www.youtube.com/watch?v=iHPEv7svzRU Sonic Mania Heroes is now a thing sorta! Interesting, he did this by changing a motobug to Sonic and it actually kinda worked. So I guess theoretically if this was refined a bit you could have a lot more than 3 players on screen. I love what can be done with this engine. If it can be cracked and tools can be developed we can finally have a classic base that doesn't have the limitations of Sonic 1 - 3K. I can't wait to see what, well more competent hackers/programmer than I can come up with.
