It’s no secret that the Raspberry Pi can emulate a number of devices, and the Raspberry Pi Pico is no exception. In his latest project, Eric Badger demonstrates the Pico’s ability to emulate a 6502 computer and shows a side-by-side comparison of the Pico running next to an Apple II computer.
According to the video description, Badger developed this homebrew emulator and ported a copy of Apple II’s Loderunner to test it out. If you’re unfamiliar with the classic title, Loderunner is a 2D puzzle game that first debuted in 1983. Its basic system requirements make it a fun choice for testing the limits of his Pico-powered 6502 emulator.
The original 6502 is an 8-bit microprocessor developed by a team that used to work for Motorola on the 6800. There are similarities between the two, and the 6502 is a more straightforward take on the 6800 processor. Overall, the Pico is more than capable of emulating the 6502 as it’s a 32-bit microprocessor, but you can find plenty of RP2040 boards that would be fun to implement for a project like this.
