Hi, I'm a game developer who mostly focuses on retro Nintendo consoles (I mostly plan to focus on SNES, Game Boy, and GBA), but I've done some PC stuff too like Petal Crash Online! All my personal projects are open source, so have a look at my GitHub if you'd like an insight on how these old consoles are programmed. I'm currently working on Nova the Squirrel 2 for the SNES!
