Title: crunching game-data files with power packer
Post by: LaserBack on September 07, 2010, 05:49:41 AM

Hi

I want to crunch a entire game using powerpacker and run the game totally crunched
but the game works if I crunch the executable file only
if I crunch the all game' data files the game does not works
is there a way to crunch all files on a game and the run it?

You could try this (http://aminet.net/package/util/pack/PPatcher).

thanks Golem !!!
I tried it and works but not works 100%
you can't crunch some data files in a game but some files refuses to works crunched
I don't know why....for example in the game turrican AGA fixed if I crunch the file "MUS0"
the game doesn't works..but the other files in this game can be crunched and the game works
btw,
is there another patch like this but for XPK compressed files?

The OS needs to be running to decompress files on the fly. When a game like Turrican runs it kills the OS, so any files that weren't decompressed before the game finishes exectuting and switches the OS off won't decompress once the game is running because it can no longer address PowerPacker from within the game.

Even if the game itself allows for OS operation and can tolerate having to unpack mapfiles etc on an as and when basis, if this is the same thing they used in the later Amiga magazine coverdisks I question how much it'd be worth anyway - I seem to recall powerpacker being exceptionally CPU intensive.
