If it's not specified, then it's random.

Thank you. I wanted to change the nature of one of my Alola traded Pokémon but wasn't sure if that would make it illegal. Didn't know about the fortune teller NPC until later. 

When trading with the NPCs in Let's Go Pikachu and Eevee, how much of the traded Pokémon is set in stone? Can they have different natures, abilities? Looking at the legality source for trades I see this:

            new EncounterTrade { Species = 019, Level = 12, Form = 1, TrainerNames = T1, TID7 = 121106, OTGender = 1, Shiny = Shiny.Random, IVs = new[] {31,31,-1,-1,-1,-1}, IsNicknamed = false }, // Rattata @ Cerulean City, AV rand [0-5)
            new EncounterTrade { Species = 027, Level = 27, Form = 1, TrainerNames = T2, TID7 = 703019, OTGender = 0, Shiny = Shiny.Random, IVs = new[] {-1,31,31,-1,-1,-1}, IsNicknamed = false, Version = GameVersion.GP }, // Sandshrew @ Celadon City, AV rand [0-5)
            new EncounterTrade { Species = 037, Level = 27, Form = 1, TrainerNames = T2, TID7 = 703019, OTGender = 0, Shiny = Shiny.Random, IVs = new[] {-1,-1,-1,31,31,-1}, IsNicknamed = false, Version = GameVersion.GE }, // Vulpix @ Celadon City, AV rand [0-5)
            new EncounterTrade { Species = 050, Level = 25, Form = 1, TrainerNames = T3, TID7 = 520159, OTGender = 1, Shiny = Shiny.Random, IVs = new[] {-1,31,-1,31,-1,-1}, IsNicknamed = false }, // Diglett @ Lavender Town, AV rand [0-5)
            new EncounterTrade { Species = 052, Level = 44, Form = 1, TrainerNames = T4, TID7 = 000219, OTGender = 0, Shiny = Shiny.Random, IVs = new[] {31,-1,-1,31,-1,-1}, IsNicknamed = false, Version = GameVersion.GE }, // Meowth @ Cinnabar Island, AV rand [0-10)
            new EncounterTrade { Species = 088, Level = 44, Form = 1, TrainerNames = T4, TID7 = 000219, OTGender = 0, Shiny = Shiny.Random, IVs = new[] {31,31,-1,-1,-1,-1}, IsNicknamed = false, Version = GameVersion.GP }, // Grimer @ Cinnabar Island, AV rand [0-10)
            new EncounterTrade { Species = 026, Level = 30, Form = 1, TrainerNames = T5, TID7 = 940711, OTGender = 1, Shiny = Shiny.Random, IVs = new[] {-1,-1,-1,31,31,-1}, IsNicknamed = false }, // Raichu @ Saffron City, AV rand [0-10)
            new EncounterTrade { Species = 105, Level = 38, Form = 1, TrainerNames = T6, TID7 = 102595, OTGender = 0, Shiny = Shiny.Random, IVs = new[] {-1,31,31,-1,-1,-1}, IsNicknamed = false }, // Marowak @ Fuchsia City, AV rand [0-10)
            new EncounterTrade { Species = 103, Level = 46, Form = 1, TrainerNames = T7, TID7 = 060310, OTGender = 0, Shiny = Shiny.Random, IVs = new[] {-1,31,-1,-1,31,-1}, IsNicknamed = false }, // Exeggutor @ Indigo Plateau, AV rand [0-15)
            new EncounterTrade { Species = 074, Level = 16, Form = 1, TrainerNames = T8, TID7 = 551873, OTGender = 0, Shiny = Shiny.Random, IVs = new[] {31,31,-1,-1,-1,-1}, IsNicknamed = false }, // Geodude @ Vermilion City, AV rand [0-5)

It looks like 2 certain IVs are guaranteed to be perfect, the others (-1) are random, their shiny status is random, their AVs are random (within range) and that's all I see. Are gender, natures, and abilities randomized too?

Is this going to continue to be updated?

I have updated my Mac OS X port to the version released 03-19-16. Download link below:

I got tired of switching to my BootCamp partition and so when I saw this was do-able, but outdated, I decided to update it myself. Here's the latest version, Feb 16, 2016 with working fonts and symbols. Self-contained and has everything it needs to run.

It worked like a charm! However, the only thing I notice is that the event code for the Prison Bottle doesn't activate, even after I got the dex entry.

1. The event is activated in the PokeMart with Hoopa in the party.

2. Try this Hoopa instead:

3. Be sure to extract and rename it pokemon.ekx
