RAM on your psp has multiple definitions. In this case..
The RAM logger is set to display the RAM of the certen area. Name/Tags/Slots
Code:
%x = RAM
%e = Float Values
%d & %s = Numbers/Letters
In this case its set to %x for RAM. So were it is normally set to %d or %s to show names and other things, we changed it to %x to show only the original RAM.

If you need to you can just look up there RAM in your browser and find information about them. As in real name, Player ID. It goes on forever but this is as simple as I can explain.
