@fer1323 They most definitely will be in the OP.
Pokemart online would be a bit overly convenient. Maybe a way to make orders to pick up at the Pokemart? I mean it wouldn't give them TMs or certain special items that'd be specific to the department stores, but Pokeballs and such, sure.
Two-way radio...maybe a phone card would be more useful?
An SOS beacon, this one I'm not really sure about one way or the other.
Waterproof would be kind of a given, I'm about 99% sure Pokedexes already are. (to record deep sea Pokemon)
Camera and sound recorder, sure those would make plenty of sense.
Instrument tuning seems pretty niche, but I guess it could be allowed.
