I agree on the rude posts. It's not because you can't code, all of us can't. I'm pretty sure I could pull it off starting from the rom's aswell.
In any case, he was sujesting to do this on his own which is a huge task. If he wants to do this as an exercise I think we should just be happy some ppl still want to help for free.
In the idea of adding this to the current game as it is, I can say this:
'It would be near impossible for one person to make this work in both 2d and 3d at the same time.'
Anywho: If you DO have an idea to accomplish this anyway, I'd love to see into the code you have so far to maybe help you out.
I mean, who knows, I'm not too proud to admit there are better coders with pretty nifty idea's.
