SpongeBob PC Games - Unknown "OmCv -OmGW" image format

[KingYoshi]

Both SpongeBob Games "Employee of the Month" and "Battle for Bikini Bottom (PC)" contain *.OMT files (also known as *.OMF2). These files are known to hold 3D Models (in root\Models) or WAV files (in root\Music and root\Sounds). They seem to be some kind of archive files, such as *.RAR or *.ZIP.



However, *.OMT files can also be found in root\Sceneart. This is the kind of *.OMT files QuickBMS 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 and The Bus Stop.png]

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 and the BMS file needed for *.OMT extraction.

Thanks in advance!

I think this should be moved to the Graphic file formats forum.
