Im new to this game want to know something simple. besides being an avid learner of anything im interested in a like to spend my time coding (computer programming, not sure how many here know the term) i have the idea of building a device, anykind, and buidling into it my own OS for it maybe in a language like C. i would just be able to load something like a game i coded myself or some other program like that. would it be possible to do that. and oh yeah im thinking of a simple dot matrix screen (that will most likely be ripped off my old gameboy) would my program have to be coded specifically for the limited capabilities of the screen. Im thinking it would have to be. The basic idea is a handheld device (like a gameboy) thats been hacked and mutilated to my desire. i hope thats specific enough.
