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

[kj911]

My test from BMP files portion the Space Empires V gamez:

This x86 ONLY compressors, its wins from ratio: MSC+DLZ
2nd place: MSC+BMP or MSC+GRZIP with any alterations.

This x64 ONLY or x86/x64 compressors, its wins from ratio: LOLZ
2nd place: MSC+LOLZ. Results ~200kB's smaller than MSC+DLZ combo.

Results:
