A ROM emulator designed for the Amstrad CPC. Shared by Hackster.io:
The emulator is designed for use with an Amstrad CPC, a color home computer first released by Amstrad in 1984 as a competitor to the popular ZX Spectrum and Commodore 64. Like many machines of the era, it included an integrated ROM while loading add-in software from cassette tape — but additional ROMs could be added in order to load software instantaneously.
“Multiple upper and lower ROMs can be stored in the Pico’s 2MB onboard flash,” Callow explains of his design. “1 lower and 8 upper ROMS are supported. A control ROM is included which allows the selection of which ROMs (from the flash) are loaded into the available slots. The Pico is overclocked to 225 MHZ, with one core providing ROM emulation whilst the other handles ROM switching and processing commands from the CPC (with the help of a PIO [Programmable Input/Output] state machine).”
