Pokemon Gen 3 Living Dex project

This pastebin will serve as the projected timeline of games played for the Gen 3 living dex project. I will do my best to notate what I can't get in respective mainline games (Ruby, Sapphire, Emerald, Firered, Leafgreen), and what I will be looking to obtain in the non-mainline games (Colosseum, Gale of Darkness). I will list the games out in the order I plan to play them. While there is no exact set order one can do this in, this is what i've decided on, with the order being switched around should I see fit to do so. Lastly, Emerald will be the game where the living dex will be housed.

What is listed below is what I currently plan to do:

Sapphire - Can obtain everything except for the following:

Groudon
Seedot
Nuzleaf
Shiftry
Zangoose
Solrock
Mawile

While Latios is, also, exclusive to Ruby normally, I will be using the Eon Ticket to get this. It will be very useful for level grinding later on.

Ruby: - All sapphire exclusive Pokemon will be obtainable from Sapphires playthrough. Just for clarity, I will need to trade over these:

Kyogre
Lotad
Lombre
Ludicolo
Seviper
Lunatone
Sableye
Latias

Leafgreen - Can obtain all Kanto pokemon except for the following:

Bellsprout
Weepinbell
Victreebel
Magby
Magmar
Slowpoke
Slowbro
Slowking
Sandshrew
Sandslash
Vulpix
Nintales
Pinsir
Staryu
Starmie
Azurill
Marill
Azumarill
Misdreavus
Sneasel
Remoraid
Octillery
Mantine

Firered - All Leafgreen exclusive Kanto Pokemon will be obtainable from Leafgreens playthrough. Just for clarity, I will need to trade over these:

Oddish
Gloom
Vileplume
Bellossom
Elekid
Electabuzz

Golduck
Ekans
Arbok
Scyther
Scizor

Colosseum - I plan (as of right now, subject to change) to get the following pokemon:

Raikou
Entei
Suicune
Ho-Oh
One of the Johto starter 2nd evolutions. I have not decided on which one as of right now

Gale of Darkness - Lugia

Emerald - Nothing specific here, as everything is to be traded over

Upon beating Emerald, I will use the Jirachi bonus disc to get Jirachi on Ruby or Sapphire, as well as using a flashcart to get the Aurora ticket for Deoxys

At this point, all that should remain is Mew and Celebi.

Japanese Colosseum - Must purify all 48 pokemon

Japanese Ruby - Must beat the game (E4) and have a free party slot

Will use the Japanese Celebi bonus disc to get Celebi, which will sent to the Japanese Ruby cart, to then trade to Emerald

Japanese Emerald - Must beat the game (E4)

Once done, a flashcart will be used to get the Old Sea Map for Mew
