Is it possible to incorporate the emu48 emulator in your hardware?
E48BP63 It is the file that contains the source code, of course, the LCD screen, keyboard and other emulation libraries are for PC processors, but it could be ported to microcontrollers or development board processors rasberryπ etc..

I don't know what the hardware requirements are for emu48. In any case, developing hardware is not a big deal these days. Mine is nothing more than a STM32 powered by a battery, with the LCD connected via SPI, and a keyboard matrix. The real issue will be writing LCD and keyboard control routines and other MCU-specific firmware like interrupt handlers and power control.
