It looks prefect for the gp2x

says it powered by opengl and it needs a 800mhz p3 with 256mb ram

sure it looks like a simple game creator but the main problem is it says you have to play the games in the client.

Add to that that NOTHING is completed yet, and most of their game packs are barely past the planning stages.

Game Editor can do all that with some programming and it already makes gp2x executables. We'd just need soome art.

apart from the fact that the "game packs" aren't really anything close to being finished, how legal is it to distribute a complete set of nintendo copyrighted material? Looks like they didn't only ripp some tiles but pretty much plan to ripp whole games. Isn't that illegal?

They may have got a license from Nintendo.

I doubt it - if they had there would have been something stating that the images were copyright Nintendo. Besides I can't imagine nintendo licensing their characters in this way.
