Numpty Physics for Symbian

The fabulous NumptyPhysics game by Tim Edmonds for Linux and Internet Tablets. It was also one of my favo0rite games on N810, and now it’s ported to your  Symbian^1 phones :)

Using the API

The Proximity sensor can be used via sensor framework. See this example )

Initializing the proximity sensor can be done with following snippet

EQ is making progress with PSX4ALL

My friend EQ has taken my psx4all dynarec port source, and after that he has added Opengl ES 1.1 support, and fixed few bugs.

He is using N95, which has hardware Opengl ES 1.1 support. I think that it’s running quite well already. Very good job EQ!
