What is CSO cache system and how to use it?
The CSO cache system is based on assumption that not all game data is required when you play a game. If you enable it and play a CSO game, a proccess will be running in background to record what data is used by current game section. Please note the game play may slow down a bit because of the extra process in background. It is suggested that you play the game by select those features and modes you will play most in future and repeat play for several time to make sure some random data is recorded by CSO cache system.
After you exit the game and return to XMB, the size information for selected CSO has two number like this <123.4/567.8MB>. The first number(123.4) is uncompressed size of recorded game data, it should be something of several ten MB for a reasonable CSO cahce file that can play. Then select "Copy to MS" to copy those recorded data from original CSO file to special folder in MS "ms0:/iso/cache". Finally, you can play those CSO cache file(same name as original CSO file) in MS just like the original CSO file.
The recoded game data information is saved in *.idx file inside folder "ms0:/dh/thumbnail" which is small in size(at most 2k) and will be accumulated every time you play the original CSO file. When you select a CSO cache file in MS, you can also see two number of size information like this <123.4/100.5MB> or <*123.4/100.5MB>. The actual size of CSO cache file should always smaller than the uncompressed size because of compression. The '*' character is indication that some new game data was recorded by CSO cache system since your last "Copy to MS" operation and you should select the original CSO file and "Copy to MS" again to make sure needed game data will be added to CSO cache file.
