Just the e-reader stuff we didn't get in Gen3 is a whole lot. Check Bulbapedia for e-reader card section. RSE/FRLG would've gotten a whole lot of replayability. If Gamefreak didn't cut "Trainer Hill" customization and the Sootopolis "Battle Basement" from the international releases, Emerald would've easily be the best game of all time. I'm talking about a CUSTOMIZABLE BATTLE TOWER of up to 8 floors of 4 different categories. Along with various shiny mons. While Sootopolis Battle Basement having plethora of trainer cards to scan & fight with different themes &
strategies.FR&LG would've gotten the same with Trainer Tower & Seven Island battle basement. All gone of course. If there's a project that can re-implement these things via wireless adapter mystery gift the way Goppier & friends implemented Eon Ticket for Emerald via mystery gift (at least the battle basement) then that would be nice.
Also check the SirToastyToes for VR trainer room general overview and DavoGato Archive (video named: Pokémon Colosseum - Accessing e-Reader Content on Physical NTSC Disk) for full gameplay.
