48G Re-creation Project (fantasy)

[EugeneNine]

looking at the emy48 source it appears to have been developed on windows which usually makes porting to something else harder.
I know the x48 code will work on ARM so I'd suggest starting with an ARM MCU such as the mso432 http://www.ti.com/microcontrollers/simpl...ing#second

which are low cost, low power, arm and some have an lcd controller, should be able to get it into a single chip solution.
