Cartridge opened at 6:05. My first guess is that under the epoxy blob, there's some mapper circuit to choose one of four GBA ROMs, with the first being the menu.

That version of PocketNES could boot in Multiboot mode, so it ran from EWRAM. Then if necessary, you could boot one game that was linked to run at the base ROM address. No mapper necessary.
You could just hack the first game to make it boot PocketNES instead, then have a special feature in the modified pocketnes to boot to the game again.

What exactly do you need GBA games on a pocketnes menu for? Unless you're manufacturing your own bootleg cartridge...

After GBA Jam 2021 is over, an entrant might want to put out a cartridge with their entry and their previous NESdev Compo entries.
