Undertale is in almost all major video game consoles of the eighth generation:
Windows, macOS, Linux, PlayStation 4, PlayStation Vita, Nintendo Switch and Xbox One.

@Random Talking Bush: I know it's impractical, it was more for the folk who are curious how it's saved raw but don't have the resources to rip it themselves. Since we're talking about missing sprites, I'll mention the few that inspired me to submit the raw dump: - Telescope from Waterfall & Editor overlays. (a few colliders are here, but far from everything).
Also, I was thinking of including a dump of the pre-assembled rooms. Would this be accepted if I organized them by Used / Unused / Etc and cleaned up the editor overlays? I want to ask before putting in the time to clean and organize all 336 rooms.

@4Bakers: We don't accept those kinds of submissions, you need to put effort into proper organization. Not to mention we already have practically everything, we don't need unorganized, almost unusable sprite dumps like that (which would also require users to manually trim junk data around each sprite, might I add).

For those who are still waiting on specific assets, you can use Undertale Modding Tool https://github.com/krzys-h/UndertaleModTool to rip content yourself.

@Pikashu2 https://tinyurl.com/5n748dnx is a Reddit post containing rips. NOTE: These rips still have the Dev overlays (overlays for colliders, interactions, events, doors, etc), every NPC in every possible state at once, missing rooms (like Snowdin Town interiors), etc. It's not that hard to mod the game to make the dev overlays invisible and export rooms as PNGs manually...

I don't know if you guys will agree or not with me here, but I think that the Backgrounds and the Tilesets sections are confusing and even a little unorganized at its current state. There are many sheets in the Backgrounds section which would make much more sense to be on the Tilesets section(like the True Pacifist Ending and the Ruins sheets. Maybe it makes sense for the Ruins sheet to be there since it has a complete rip from the entrance area of the Ruins, but the sheet from The Core also has a similar rip from the Core entrance and it still is on the Tilesets section). But I think what contributes the most for the confusion is that most sheets on the Backgrounds section already have a tileset rip from their respective areas, and thus making the Tileset section underused. I have no clue about how to organize them in a better way, but I just wanted to point this out.

i still don't know where the hotland marquee is

can someone please just make all the rooms in one sheet, cause it's so hard to recreate it using tilesets

where is mad mew mew?

edit: oh nvm sorry

Where is the "welcome to hotland" marquee?

does anyone know where the warning boxes are? the one asgore and mettaton uses?

@casteor573 That's an actual font, and it's not stored in an image or anything like that.

Happy 6th, Undertale!

A great game, cool mechanics, good story, but the internet ruined the game

If I remember correctly you can turn the solids sprites visible by using a debug method, so technically they are 'used' in game but you shouldn't really ever actually see them. I'm not saying move them or anything, just pointing it out.

@pugsforlifebruh12: If it's completely invisible, does it even count as being used?
