thats very interesting ill investigate on the files neededYes, only if you are on a system version which allows you to use hacks, homebrew and Cafiine. (5.3.2 or less)
instead of replacing the file and use loadiine, you replace the file on the fly from the network when the disc access them.
if the replaced file is very big, it can be an issue. either crash, or long load time as it will have to transfer it again for every access.
