NES86: x86 emulation on the NES

The goal of this project is to emulate an Intel 8086 processor and supporting PC hardware well enough to run the Embeddable Linux Kernel Subset (ELKS), including a shell and utilities. It should be possible to run other x86 software as long as it doesn’t require more than a simple serial terminal.

Is this useful in any meaningful sense? No. Will this change the word? No. Does it have any other purpose than just being fun and cool? Nope.

None of that matters.
