Meh!
You must have emu8086 installed.
I admit it: this won't be the prettiest code you'll see. I did it for college, so give me a break. But if you're not familiarized with8086 instruction set, here's a nice guide. And, if you like a little bit of history, this book is very cool.
To compile it, you don't even need to understand assembly. Just open main.asm using emu8086 and click in that nice button called "compile". After that, you just need to wait a little bit and a window will pop up. Choose any directory you want to save the compiled file and then click "run".
That's it!
