Thrillville (PS2/XBOX) .ovl archive

[Novarleeir]

Thrillville uses primarily two archive types, .ZAP and .OVL. The zap files tend to act as a container to hold numerous ovl files. Thankfully there are already tools made that allow you to extract files from the zaps, however, all of the game assets are still locked up inside the ovl(s). I would very much like to figure out how to extract at least textures and models from the ovl files since there is no current way to extract any of the data besides the music which is stored in .aud files.

Unfortunately, current tools such as Cobra Tools does not support older ovl formats: https://github.com/OpenNaja/cobra-tools/issues/132

The following image are the contents of ovldata.zap, and seems to contain pretty much everything except for music which is stored in a different zap file:


Using a tool like Texture Finder, you can see that there are indeed images within the files:
Later on, in the Main.ovl, you can find bits of data that represent models for the game (likely in .mdl)


Here is a rar with the Main.ovl, TitleScreen.ovl, and Main_English.ovl (Main has a bunch of random stuff in it, TitleScreen only has one image, and Main_English seems to be localization strings):
ovl.rar

I'm not sure if the format is the same for Thrillville: Off the Rails, but it's possible that if an extraction method is made then it can also extract the files from that as well. Off the Rails is even on Steam, so it may be a bit more convenient to access the files: https://store.steampowered.com/app/6080/Thrillville_Off_the_Rails/
