Yeah it depends on how much you’d use it I guess. I remember playing some old titles on a GBA emulator app back during highschool breaks, but it kinda got old quickly. Would be pointless to buy something specifically for it unless you’re really into it, but if so something like this that’s well integrated would be pretty neat to have.

If it can do it with just that then it’s sensible to have less, since idling memory will use power and the less you have the longer the battery will last.
