Any electronic/robotic gurus here?

I have been thinking about making my own video game console for awhile. maybe the power of SNES as thats like hte greatest console ever.

anyone know how this can be done? all advice besides "dont attempt it" will be helpfull.

Yeah. Find a forum dedicated to hardware and robotics.

That doesn't really sound like robotics, frankly. If you look for robotics, you will mostly find motion based things. If you know the processor that you want to work with, look for a forum for that processor alone. I think there is a forum for EVERY microprocessor out there. I only follow the OOPic forum, but there are some for BASIC Stamp and Motorola, and there are almost certainly plenty more.

You would have to program a microcontroller to respond to inputs on its ports. The controller would then transmit the serial information to the serial port where you can receive the input stream and decode it by your own program. If you were thinking about making money from this device then you would have to write a device driver in C to expose events to other higher level programming languages.

Lately it seems the way to go is to use the USB port for everything so your device should be USB compatible.
