sweet, I am really interested to see how this runs on the D1.
I'm the Dave that p3 references in his post on MDW. This project was born out of my desire to play Madden on my D1. I am rooted and running a 1.2GHz kernel, but for the fun of it I set the max clock to 500MHz (closest thing my kernel had to 600MHz stock).
Even at 500MHz, the game runs suprisingly smooth. Not AS smooth as it does at 1.2GHz, but very minor slowdown. My guess would be that on a stock 600MHz D1, it will run great. Throw in a bit of an overclock, and you're looking at basically zero slowdown.
