Not necessarily… When the emulator includes proprietary pieces -bios/etc- it’s subject to copyright. Without said pieces it’s not much of an emulator… Iirc GBA emus fall into this
I am pretty sure a number of emulators do have reverse engineered bios that provide very good compatibility. I have some of those retro handhelds that run on ArkOS, and quite a few of the emulators in Retroarch do have that option. It’s not perfect, but works for most of the games I want to play.

That’s why GBA emulators ship the proprietary parts separate. You’re on your own to track that down.
What if those are reverse engineered?

Xemu is one of those, there are a few reverse engineered or otherwise nonproprietary bios options available
