Dario, this is nice and all, but I think it's a very bad idea to promise all sorts of things without showing anything off. If you plan on dramatically changing the MP9 game engine, you have to show that it's actually possible and that you've done it.
And to that, I think it's near impossible to be making the kind of changes you want. To redo the entire game engine to fit the classic style, that is going to require some serious modifications, and I don't think I've ever seen anyone do something that drastic in a ROM hack before...
I love what you do with bringing back old characters, but I don't find this believable or doable...
