Best Compression Methods for 'Specific' Games. Q&A

[Masquerade]

In it's retail state (just like all other LEGO Games) this game is impossible to compress properly. In order to make a decent conversion, you first need to use QuickBMS on the DAT files to unpack them.

You can download QuickBMS here.

You will also need the TTGames BMS script which you can get here.

Drag the BMS script over the QuickBMS EXE file and select all the DAT files. I like to unpack to a separate folder then merge the files after unpacking, but it's perfectly fine to unpack to the game directory.

After unpacking, move or delete the DAT files since we no longer need them.

Test the game to make sure it still loads correctly, it will load from the raw asssets just like it would from the DAT files.

Total retail size: 7.42GB

Total size after being unpacked using QuickBMS: 12GB

Thanks to darkwolves for the original conversion.

Note: Not much smaller compared to darkwolves conversion, but still fun to have a go.
