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

[L33THAK0R]

I'm very new to lzo1x pre-compression, could anyone explain why XTool in this example is able to detect some streams but not able to process any? I've tried levels 1 - 10 and the same amount of streams are detected but none are able to be processed

All done.

The algorithm used is definitely lzo1x, and creating a database with bms2xtl detects an additional ~5000 streams but alas none are detected. I've also not been able to find many other lzo libraries to test with so if its a library issue, if anyone could point me in the direction to look for others it'd be greatly appreciated.

maybe you need to remove the level option, sometimes it works.

Unfortunately seems like some data actually got stripped away doing that, resulted in a 99.51% ratio

Maybe used pro-functions. Upload example file for testing

Thanks for offering to have a looksie, really appreciate any insight you can offer, also in case its of any interest I've also got an LZ4 sample I've been having similar issues with, tried about a dozen libraries but no dice so far, xtool (0.6.5) is also detecting streams but unable to pick any up unfortunately.
