Hello Daniel, Luke and everyone.

I want to introduce you to Peter Bouda.

He has contacted me because he liked the project.

He is a software developer ( http://www.ubrew.it/ ) and he has offered help to develop the software of the handheld games console.

He does not know a lot about hardware design, but he has told me he will try to learn more about this to help in the design of hardware. So maybe soon he can also help in the design of hardware.

Thanks!
