In the 1990s, when I was in college, I wrote a 6502 emulator in a text editor macro language (the text editor was QEdit, a DOS editor that was popular at the time). It was completely useless but a lot of fun.

There was a very low hard limit on the number of jumps (32, if I recall correctly) that complicated things. I eventually had to resort to a two step process, first translating 6502 code to a simpler virtual machine (using and abusing the find-and-replace command), and then executing that simpler code.
