Thanks for the interest. Im putting together a demo now, for an extremely small screen size.
I imagine if you gpu accellerated the bitmap comparisons (just the test that finds what sequences are valid after the current frame) it could run hd maybe.
Its definitely an oddity of a technique, and it has disadvantages... like file size for example... it sorta stores the whole thing in parallel and there is lots of states to store.
I would explain more, but im not sure if there is any point at this stage - what I really need to do is post a working prototype then people would see what im raving about.
Just imagine drawing a stick man battle and be able to hook controls up to it to play it... thats what it could do.
