I'll update this, since you can't PM people here anymore, if you want to help rip from this game, or you have an old, uncleared Roblox cache after playing it, DM me on the Discord (same username)

Also PM me if you played it a long time ago and have an old, uncleared Roblox cache.

If anyone wants to help with this, PM me for pointers.

OH GOD NO NOT SONIC SPEED SIMULATOR

There's a way to rip assets that aren't currently displayed in the game, but it's a lot of trial and error, if you're up to it.

I would like to help with this what's the best way to rip files. I was originally gonna try blue stacks + ninja ripper but i see in the comments it ruins the image quality

Note: Bluestacks + Ninja Ripper method actually degrades image quality, meaning a lot of my older rips are not native quality. Unfortunately, I can't re-rip these graphics uinless they're either still readily available in the current update, are used again for a future update, or I figure out their asset ID.

i have a suggestion for you to rip some sprites from roblox. and the game is called Pillar chase 2.

Yeah, I might give up on this. The asset library pages are now redirecting to Creator Hub pages, which take longer to load and often result in a 404 error even when they're actually there, requiring many refreshes to actually see the asset.

That is indeed helpful, I just wish I could get the URLs too...

By the way, don't attempt to rip from this game if you care about upcoming updates being a surprise. I can confirm that a character they teased on Twitter indeed has an icon in the latest sprite sheet.

Bad news: while it's possible to view assets that aren't currently in the game if you have the correct URL, some (not all) old assets, mostly pre-Sonic Shock, are set to private. I discovered this searching the Wayback Machine's archived URLs under www.roblox.com/library/. For example, if you remove the snapshot URL from this:
https://web.archive.org/web/20220804042741/https://www.roblox.com/library/10467271864/Images-Knuckles-Riders-Render-LG
it becomes this:
https://create.roblox.com/store/asset/10467271864?externalSource=www

Just found this program called BloxDump, it takes all currently loaded assets and dumps them on your computer, meaning you no longer need .dds files and Bluestacks. Idk if it fully works tho cuz i havent tried actually ripping stuff yet

By the way, if anyone is willing to help, that'd be great. You can use Bluestacks and Ninja Ripper as previously mentioned, but if you know the asset ID (you can catch them in real time using Roblox's built-in memory monitor -- if you're fast enough -- also as previously mentioned), you can get them using any Internet browser. I'm particularly interested in ripping assets that were used in events that have ended, like the latest April Fools event, which only lasted a day (and I totally missed it), as well as anything from the original legacy version of the game. The "Reborn" logo from the title screen of the post-wipe's first few updates is also lost. I'm working on archiving the actual URLs of the assets I can find. I might start a thread over in Project Organization, if anyone's interested.

Apparently only if they're professionally-produced. This one was made under official license from SEGA.

Rips of ROBLOX games are also allowed on TSR?!

can't seem to use ninjaripper on the roblox client nor bluestacks, pressing the hotkey for ripping textures just does nothing and when doing it after clicking on the top of the window rips bluestacks assets
Edit: yes lets go i found out how to do it

you go to memory and i scroll down to "graphicsTexture", and i put in the IDs of the graphics into a link from a decal. it's the only way im aware of
the link i put in the ids is https://www.roblox.com/library/IdHere/anything-can-be-put-here
