As a reference when looking up lines from the game, I've used LightSoul's Final Fantasy VIII script, hosted at Icy Brian's RPG Page.
To check body language in scenes from the game, I've used Xenomic's walkthrough on YouTube.
The Balamb Garden background images and assorted Balamb Garden Network assets are from Reddit user Wimbly_Donner. You can frequently find Wimbly playing Final Fantasy VIII on Twitch.
In a couple of cases, when the base background image is missing important details (e.g. the barriers and guard at the gate), I've created composite images blending Wimbly_Donner's background images with screenshots from Cool Ghost's Final Fantasy VIII Let's Play.
The Balamb Garden exterior image and the animated character sprites come from Creative Uncut.
The image of NORG comes from The Models Resource.
The screenshots of Garden Square comes from Reddit user MetallHengst.
Other Final Fantasy VIII screenshots were taken by the Steam community. Thank you to the Steam users kujo, Leelah, MiCi462, muggling, sg_epk_jtk93, thekarelov, presidentjapan, victorviegas and Squall Leonhart. Thanks also to Sweety Ashley for the shot of Bodhum from Final Fantasy XIII.
Other resources
The coding on this website is generally very simplistic, but occasionally I've attempted to do something fancier. I've found W3Schools a helpful resource when I haven't been sure how to do something in HTML, particularly its code tester.
The picture of Midgar from Final Fantasy VII comes from this article on the official Square Enix website.
The image of Final Fantasy XV's Galdin Quay comes from gojjosatoru on Tumblr, and the image of Gladio reading comes from ChilledFoodTin on Twitter.
The picture of Final Fantasy XVI's Hideaway comes from Reddit user hypespud, who has shared almost five thousand Final Fantasy XVI screenshots in this Flickr folder.
The screenshot of Missingno was taken by Ash McGowen, who goes by the name Kung Fu Man on Wikipedia. Yes, there's a picture of Missingno on this Final Fantasy VIII website. I promise there's a reason.
