right now all files are required for repacking, but i intend to make an 'insert new files only' mode in the next version. you can leave the -txt and -f parameters, and can use only '-m e' for extracting or '-m r' for repacking. the extracting bug was fixed in toxpack.
i added a few repacking options. if a file has different size than the original, the repacker fixes the header file. but if it is the same, there is no need to touch the values, and because repacking can take long time, i added the option to repack the header and data file separately (and it was easier to test the program this way).
when you copy the files to ps3, you actually don't have to do anything in the original game folder. the game always uses the install data, so you only have to replace those files. this also means that the game will work from original disc too.
Oxinar: the file will not work, because the starting offset of the texts are stored. i will make an editor for it, but you're working fast
