Unencrypted PRS-compressed .gci Quest Extractor
This is a specialized tool written specifically to extract quest .bin and .dat files from .gci dumps of
Gamecube memory card quest files that were saved using a special Action Replay code which enabled an embedded
decryption key to be included in the save file, following this the data was manually decrypted with that key.
Put another way, this tool will only work on .gci files found on this gc-forever.com forum thread.
And even then, only if they are labelled as "unencrypted PRS compressed quests". It will not work on the quests
found there which are labelled as "encrypted quests w/ embedded decryption key."
You CANNOT use this tool to extract quests from any arbitrary .gci file you have on your Gamecube memory cards!
(Maybe one day someone will reverse-engineer the method in which PSO derives the encryption from the player's serial
number and access key. But until then, it is not possible for this tool to work with any arbitrary .gci file.)
Usage
Quest files on a Gamecube memory card are split into two files per quest. One file contains the quest .bin data, and
the other contains the quest .dat data. Therefore, two .gci files are needed for each single quest.
gci_quest_extract <quest_1.gci> <quest_2.gci> <output.bin> <output.dat>
For example, in the aforementioned gc-forever forum thread, you can download a zip of quests in .gci files. Consult
the included text file for information about which files are for which quest. Then you can run this tool using
something like this:
gci_quest_extract /path/to/8P-GPOE-PSO______022.gci /path/to/8P-GPOE-PSO______023.gci quest.bin quest.dat
This will extract the quest found out into the files quest.bin and quest.dat.
This tool will automatically try to figure out which of the .gci files provided is the quest .bin file and which
is the quest .dat file, so if you mix up the order, it should not matter. However, it is entirely up to you to make
sure you provide matching files for the same quest!
