@BigDawg869789 Phantasy Star IV
@BigDawg869789 The game is a bit of a cult classic so prices might be high on that one. If you get a flash cart you can just download ROMs to an SD card and play them on real hardware.

Crusader of Centy is also a good one. It's an action-adventure game that plays similar to 2D Zelda, but once again the cartridge is pretty expensive.
