What is the game engine that Dong Dong Never Die uses?

I think it's a MUGEN joint, right?

@iodine: Thats what I thought, but that's not what it looks like when they pick stages.

2D Fighter Maker

Yeah, pretty sure it's Enterbrain's Fighter Maker.

But who really is Dong Dong?

@redking56: He is the first character on the character select screen, in the top left corner (named 东东, "Dong Dong"). The character on his back in his win pose is 東, which is also "Dong". If the TV Tropes page for the game can be trusted, Dong Dong Never Die and Terminator 2 have the exact same plot, with Dong Dong taking the place of John Connor.
