I’m sorry about the “experience” you had with gba-modern :D In fact, I never thought it to be a reusable library, more something I could use to make my own games myself. At some point I thought into separating it in libraries and reusable components, but I never really went that far, which is a shame, since there’s a lot of code and research there that I’m proud of. I hope you have the best of luck with your game!
