I strongly recommend upgrading your GBA if you still have it - you can get an IPS replacement screen (bare minimum, it's an enormous improvement), USB-C Lipo battery, new shells/buttons, louder speaker, etc. I think it costs around $100 for the lot, but it breathes a lot of life back into the platform. Personally, I prefer the standard GBA for superior ergonomics, and the lack of moving parts (and it's the one I had!)
