I've been following GamingMonsters's gbdk Gameboy Dev tutorial (it's rad! https://www.youtube.com/playlist?list=PLeEj4c2zF7PaFv5MPYhNAkBGrkx4iPGJo).
Was doing this for my own reference, but thought I may as well flesh out & share I'm on MacOS, so have put together anywhere I've had to do something different, I'm up to Session 10, so will update if anything further comes along as we progress.
Quick heads up, before you run anything here make sure you know what it's doing, this all worked fine and dandy for me, but I'm not making any promises!
