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 okay, it will load from the raw asssets just like it would from the DAT files.
Total Unpacked Size: 9.4GB
Compression as follows:
- The following passage is required in Arc.groups:
Code:
$ogg
*.ogg
$wav
*.wav
$bink
*.bik
- Compress using the folowing:
Code:
srep:m3f:l512:v2+lolz:dt:dtb1:dtw1:dtm1:dto1:dtd1:mtt1:mt4:d64m:fba4096/$wav=msc:wav=1:frog=9+srep:m3f:l512:v2+lolz:dt:dtb1:dtw1:dtm1:dto1:dtd1:mtt1:mt4:d64m:fba4096/$ogg=oggre/$bink=bpk
- I used FROG instead of TAK for MSC because TAK caused a crash. FROG works fine...
Total Packed Size using above methods: ~1.74GB
