"Hi! I'm trying to make a mock-up of a SNES song, trying to make it sound like it's from the GBA.
I'm using FL Studio with the Super Mario Advance 4 soundfont, a bitrate limiter, sample rate at 11kHz, and 8 bit depth. However, even when I've done all of this, I can't achieve the GBA sound I'm looking for. Do you think you can help me with this?"
