" The ability to load modules from the memory stick. "

what exactly does this mean and whats the benefit?

it means you load mudules i.e. mp3 player module, cheat devices etc. without having to write them to the pspbtcnf_game.txt and the flash, it also gives you the option to enable\disable them any time you like. and it reduces the amount of writing done to the flash0 which equals less chance of brickage.
