i have a game in pkg format that is in 2 parts for eg.

god of war 7 part 1.pkg
god of war 7 part 2 .pkg

part 1 to be installed first then part 2 in order for it to be installed on hdd or ext hdd

now i was wondering how to make other 4gb+ pkg's multi-part installable

now i do not want to make a large pkg file split on ext hdd then copy to ps3 hdd using mm in order to rebuild pkg as a single pkg i want to know how to make a multi - instalable part pkg file like the game described above

i hope this makes sense as it has my head spinning lol
