PSA: The GBA Ambassador games on 3DS can be exited by pressing the HOME button on the 3DS, and then pressing 'A' to return to the 3DS dashboard.
Jonny Metts seems to be under the impression that the 3DS has to be manually turned off in order to boot out of GBA games, but that's not true. He may be confusing the 3DS's DS mode with the GCN mode on the original Wii, which DID require you to manually shut the entire system down in order to get back to the Wii's home menu.
Another fun episode, though. I enjoyed Gii's uh..."mouth noises" (lulz) and TYP's
Smash Bros. advice. (lulz again)
