yea i saw that but it dosen't cover everything nor does it say where pokemon are. I thought of 100% this game but it feels too rng since you a shiny of every pokemon aswell as other daily achievements
i wouldn't try 100%ing it, shinies are very tedious, even with shiny flasks. personally i'm going for every legendary, and seeing at least one pokemon in every evolutionary line. i'll give you some info not included in the guide.
Solar & Lunar Sanctuaries
Once the Pokemon needed are obtained, Latios (Lunar) and Latias (Solar) will appear on the bottom floor. They will remain there, even if you leave and change your party.
Other Legendaries
Rayquaza is atop Mt. Silver; Past the rocks.
Kyogre is at the end of the Storm Shortcut in Kanto; Past the rocks.
I found Articuno in Seafoam Cave, Zapdos in the Power Plant (teach a Pikachu surf and take it to Route 38), sadly forgot about where Moltres is.
Ho-Oh is at the end of the Burned Burrow. Haven't found Lugia.
Deoxys is at the end of Route 53.
TMs
You can find Prismatic Pledge is obtained by defeating the Pokemon Champion, a 120 Power special move usable on starters, Mew, and Mewtwo. Changes alongside primary typing (Only 1!)
You can find Metallic Slash is obtained by winning the battle at the end of Route 25, or in a vessel at Mirage Island.
You can find Prismatic Quack by winning the battle at the roadblock to Mt. Silver, or in a vessel at Mirage Island.
From what I understand, the discs in Tarpatch town are capable of giving any Pokemon almost any move; Except for a few such as the three above, and several signatures.
Misc.
There's a man in a house at the end of Route 46. He'll give you Running shoes, which decrease the amount of encounters needed to go through grass.
In Marble City, there are a multitude of important items. A man in a house gives you the Wide Lens,which is used at the light house in Olivine City to reach Mirage Island. Another gives you the Red Scale, necessary for receiving the Power Bracelet and completing the rock smash quest, allowing you to click on and break rocks. There's also the Farfetch'd Leek (Choose either choice for the chef), and the Moomoo Milk (Bring a Miltank to the farmer).
also, for the battle center, i've found it extremely worth it to spend a metallic slash on metagross. it killed basically everything.
let me know if you've still got questions
