How do you stay motivated as a beginner in coding?

I’m new to coding and recently got curious about how PS2 emulators like PCSX2 work — especially the role of the PS2 BIOS. I’d love to eventually build or contribute to retro gaming tools, but I’m not sure where to begin as a CodeNewbie.

What are the best programming languages, projects, or learning paths if I want to understand how BIOS files, emulation, or low-level game systems work?
