DDLC 100% CG Guide - Special Ending

Since it keeps getting asked, here's the most efficient way to collect all CGs for the special ending.

-> Get a fresh install of the game. You can do this by deleting firstrun in your "game" folder, and then choosing to delete previous save data.
-> Save at first poem minigame.
---> Make first poem for Sayori.
---> Get first Sayori CG: Buttoning up her jacket.
---> Make second poem for Sayori.
---> Get second Sayori CG: Icing her forehead with apple juice.
---> Third poem doesn't matter, but for posterity's sake you can make it for Sayori too.
---> Choose to help Yuri over the weekend.
---> Get third Yuri CG: Washing her face.
---> Tell Sayori that you love her.
---> Get third Sayori CG: Hugging it out.
-> Reload your save at the first poem minigame.
---> Make first poem for Natsuki.
---> Get first Natsuki CG: Read against the wall.
---> Make second poem for Natsuki.
---> Get second Natsuki CG: Manga box upskirt.
---> Third poem doesn't matter, but for posterity's sake you can make it for Natsuki too.
---> Choose to help Natsuki over the weekend.
---> Get third Natsuki CG: Press 'F' to finger.
-> Play as normal from here.
---> Write your first Act 2 poem for Yuri.
---> Get first Yuri CG: Reading together.
-----> If you make your first Act 2 poem for Natsuki instead, you get her first CG with some added spookiness. Unless you reloaded a second time in Act 1 to get Yuri's CGs beforehand, you'll lose out on 100% completion.
---> At this point you get railroaded onto the Yuri route, so it doesn't matter who you write your second Act 2 poem for.
---> Get second Yuri CG: Gimme the chocolate, MC-kun.
-----> If you wrote both poems for Natsuki, then you'll get a special spook scene when you choose to share with her.
-> Play as normal from here.
---> Get Monika CG: JUST MONIKA.
---> You can stay with Monika for as long as you like. When you get tired of best girl, delete monika.chr from the "characters" folder.
-> Play as normal from here.

Congratulations! You got the "good" ending!

BONUS ROUND
This is how you get both versions of the Sayori's Special Hangout ending.

-> Get a fresh install of the game.
---> Delete sayori.chr from your "characters" folder.
---> Start a new game.
---> This version will just cut to the END screen and Sayori's Special Hangout.
-> Get a fresh install of the game.
---> Delete monika.chr from your "characters" folder.
---> Start a new game.

In both versions, if you stick around for about 10 minutes you'll get a special message from Sayori.
