Title: Unknown "OmCv -OmGW" image format (in SpongeBob PC Games)
Post by: KingYoshi on August 09, 2017, 01:14:02 pm
There's this unknown image file type, which can be found in *.OMT files (a sort of archive format, also known as *.OMF2). *.OMT files are used to store models, musics or images in "AWE Games" PC videogames, such as SpongeBob SquarePants: Employee of the Month, SpongeBob SquarePants: Battle for Bikini Bottom and Jimmy Neutron: Boy Genius.

In both SpongeBob Games "Employee of the Month" and "Battle for Bikini Bottom (PC)" *.OMT files hold 3D Models (in root\Models) or WAV files (in root\Music and root\Sounds).

However, *.OMT files can also be found in root\Sceneart. This is the kind of *.OMT files QuickBMS (http://aluigi.altervista.org/quickbms.htm) can extract and they probably contain image files. In these SpongeBob PC Games, most "art" like backgrounds are 2D. 3D Models are actually only used for the characters and enemies. [CaveJumper.png (https://zenhax.com/download/file.php?id=2811) and The Bus Stop.png (https://zenhax.com/download/file.php?id=2812)]

However, the extracted files have no extentions so I do not know how to open them. Online file identifier TrID also won't recognise the file format. When opened in a Hex Editor, the first line says "OmCv -OmGW" but that doesn't make clear anything to me.

I was hoping you guys could help me with this, 'cause I'd really like to be able to rip and open image files from these SpongeBob PC Games. :)

I attached world01.omt from "Battle for Bikini Bottom" and a screenshot of the Worldmap of that game. The images shown on the Worldmap likely are stored in that *.OMT file.

  • QuickBMS (http://aluigi.altervista.org/papers/quickbms.zip) and the BMS file (http://aluigi.altervista.org/bms/spongebob_omf2.bms) needed for *.OMT extraction.
  • world01.omt and Worldmap screenshot (https://zenhax.com/download/file.php?id=2815)

Thanks in advance!

Hi!

Thanks for the detailed info.
Unfortunately I don't have anything useful to add about this file format.
