E reader emulation for gba cores?

Would love not to need a computer every time I want to use the e-reader in pokemon and other games, is it possible to add this to the vba m core since the standalone emulator supports this feature. Don’t know if the standalone mgba has E-Reader support yet but if it does add this to the mgba core too then.

Currently all the gba Emulators in and out of Google play can’t emulate the e-reader yet and I don’t see them planning to add it anytime soon

No, you can’t use the e reader in mobile because theres no 2nd screen on the android emulators
