Faux86: A portable, open-source 8086 PC emulator for bare metal Raspberry Pi

Faux86 is designed to be run 'bare metal' on a Raspberry Pi. This means that the emulator runs directly on the hardware so no OS needs to booted on the Pi.

Features

• 8086 and 80186 instruction set emulation
• CGA / EGA / VGA emulation is mostly complete
• PC speaker, Adlib and Soundblaster sound emulation
• Serial mouse emulation

Usage with Raspberry Pi

By default Faux86 boots from a floppy image dosboot.img which in the emulator is mounted as drive A. The SD card will be mounted as drive C and any connected USB mass storage device will be mounted as D. Since MS-DOS is accessing the SD card directly, it does not work for large SD card types. I have found the best solution is to use a small capacity SD card and flash the image as a 32MB card. USB keyboard and mouse should be plugged in before booting - hot swapping of devices is not supported.

Credits

Faux86 was originally based on the Fake86 emulator by Mike Chambers. http://fake86.rubbermallet.org A lot of the code has been shuffled around or rewritten in C++ but the core CPU emulation remains mostly the same.

Faux86 uses the Circle library to interface with the Raspberry Pi https://github.com/rsta2/circle
