How to identify the correct libraries to be loaded for each game by using the log?

Either a game will use a certain module, or not. If the game doesn't use a certain module I don't think performance is affected. Loading unused modules shouldn't affect compatibility either.

HLE stands for "high level emulation". There is more here: http://www.emunewz.net/forum/showthread.php?tid=165781

And for each term there is a corresponding Wikipedia article...

To tell you the truth, I searched a few terms on the wiki today. I searched the modules, I saw an interesting tree on the dev_flash folder. At that point I've come to consider the possibility of "spurs" simply being part of some other LLE.

I already knew the topic too but I forgot him in the search for the corrects LLE's, tried to search inside the pastebin with the modules. A quick read on the topic and I've solved some 4 doubts I had. The only thing left by now is the color which is not very important and it's more for curiosity. You know what the colors mean inside rpcs3 log? After many tests I got the impression that:
Cyan Blue = Just RPCS3 Version
Green = Good
Orange = Bad, but often it's possible to solve
Red = Bad
Pink = very bad

But I do not know if this is a precise guess
