I always use aldotools for game packages, but a few people were interested in adding features to other pkg tools. xgpkg BETA for retail ps3 game packages. support for large files. xgpkg.exe 0.2.2 Usage: xgpkg.exe filename option option: -a, extract all -e, extract selfs and sfo's -f, fix selfs and sfo's; WARNING!, proccesses in place IMPORTANT! option f processes the pkg in place. please only use this option with a back up copy of your game package. the other options open the input pkg as read only. options a and e create output directory from content id. option f creates a pseudo retail pkg. To use this on cfw 4.21, I had to patch na5_plugin.5sprx. see post 2 for patches for 4.21. also, I don't know about fixing or resigning sdats or edats, so this fixes only eboots, sprx, spu and param.sfo types. WARNING na5_plugin.5prx is a firmware module in dev flash. edit at your own risk.
