So, I hear you like emulators. It turns out that Go is a great language for writing retro-computing emulators. Here are the ones that I have tried so far:
trs80 by Lawrence Kesteloot
I really liked this one because it avoids the quagmire of OpenGL or SDL dependencies and runs in your web browser. I had a little trouble getting it going so if you run into problems remember to execute the
trs80 command in the source directory itself. If you’ve used
go get github.com/lkesteloot/trs80 then it will be
GoSpeccy by Andrea Fazzi
GoSpeccy was the first emulator written in Go that I am aware of, Andrea has been quietly hacking away well before Go hit 1.0. I’ve even been able to get GoSpeccy running on a Raspberry Pi, X forwarded back to my laptop. Here is a screenshot running the Fire104b intro by Andrew Gerrand
Fergulator by Scott Ferguson
Like GoSpeccy, Fergulator shows the power of Go as a language for writing complex emulators, and the power of
go get to handle packages with complex dependencies. Here are the two commands that took me from having no NES emulation on my laptop, to full NES emulation on my laptop.

sms by Andrea Fazzi
What’s this? Another emulator for Andrea Fazzi ? Why, yes it is. Again, super easy to install with
go get -v github.com/remogatto/sms.
Sadly there are no sample roms included with Update: Andrea has included an open source ROM so we can have a screenshot.
sms due to copyright restrictions, so no screenshot.
Update: Several Gophers from the wonderful Go+ community commented that there are still more emulators that I haven’t mentioned.
