A tool for extracting Sonic the Hedgehog 4: Episode II's OBB file.
Sonic the Hedgehog 4: Episode I's OBBs are unsupported due to them using a different format. Use QuickBMS and the "vector.bms" script to extract it (it also works with the DZ files as well since they're the same format as the OBB file).
Notes:
- Repacking the OBB files is not possible. I do not plan to add a repacking feature, especially since I'm not familiar with C#. Sorry, guys. :(
- The OBB file in the OUYA version of Episode II has a renamed extension (.ogg). This file's extension will have to be changed to "OBB" for the program to work.
- OBBExtract was compiled from this commit by RadiantDerg.
(Special thanks to a few members of the TSR Discord server for helping me compile this program!)
