Endless Paradigm

Today I got two ideas for PSP homebrew

First off, seeing the new Dungeons mod that Shizzy posted gave me an idea. What if someone took the Dungeons 3D source code and modified it, keeping the basic gameplay, but improving on everything else? I'm talking about better AI, more weapons, bigger levels, puzzles, that sort of thing. Hell, what if someone added multiplayer?

My second idea is for a fighting game. Someone needs to make a good, open 2D fighting game for PSP, where people could add their own characters, and each character has distinct movesets. Basically, Mugen for PSP. Also, if anyone is willing to try this idea, I'd be willing to help with graphics.

bigger levels are already possible in psp dungeons
but about improving the engine i don't know if the engine source has been released by the creator of psp dungeons but i believe the creator charnold is himself improving the engine

It would be great if someone had the time and willingness, first...

i think someone tried that 2D fighter idea and failed at it

I like 2d fighter games but I don't like the Phat PSP D-pad.
