Writing an emulator was on my list of “wizardly things beyond my reach” (along with compilers), but I highly recommend burning down that list. While creating a complete and shareable emulator is a big undertaking, making a simple one for fun is surprisingly not too bad.

You should expect to do a lot of reading though, and you’ll become very familiar with how the system you’re emulating works :-)
