+# PSO Ep I & II Gamecube Tools
+
+A small collection of tools, intended to assist with my own efforts in investigating how download/offline quests need
+to be prepared in order to work correctly and tools to automate that process.
+
+## Tools
+
+* [bindat_to_gcdl](bindat_to_gcdl.md): Turns a set of .bin/.dat files into a Gamecube-compatible offline/download quest .qst file.
+* [decrypt_packets](decrypt_packets.md): Decrypts server/client packet capture.
+* [gci_extract](gci_extract.md): Extracts quest .bin/.dat files **only** from specially prepared Gamecube memory card dumps in .gci format. This is a highly specific tool that is **not** usable on any arbitrary .gci file!
+* [gen_qst_header](gen_qst_header.md): Generates nicer .qst header files than what [qst_tool](https://github.com/Sylverant/pso_tools/tree/master/qst_tool) does. Can be then fed into qst_tool.

+# PSO Ep 1 & 2 (Gamecube) Quest .bin/.dat to Download .qst Tool
+
+This tool takes a set of `.bin` and `.dat` files for a Gamecube quest and turns it into a `.qst` file that can be
+served up by a PSO server to Gamecube clients as "download quests" which can then be played by Gamecube users directly
+from a memory card.
+
+## Usage
+
+Given two files, `quest.bin` and `quest.dat`, a download quest file, `download.qst`, could be created using:
+
+```text
+bindat_to_gcdl quest.bin quest.dat download.qst
+```

+# PSO Ep 1 & 2 (Gamecube) 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 included an embedded
+decryption key in the save file and then were manually decrypted with that decryption key.
+
+Put another way, this tool will **only** work on `.gci` files found on [this gc-forever.com forum thread](https://www.gc-forever.com/forums/viewtopic.php?f=38&t=2050&start=75).
+And only if they are indicated to be "unencrypted PRS compressed quests" and **not** "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 the Gamecube client derives the encryption key
+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 need to be provided to this tool. 
+
+Special care should be taken to ensure that the two `.gci` files you provide are a matching pair **and** that they are 
+provided in the right order! **The file containing the `.bin` data should be specified first.** 
+
+```text
+gci_extract 8P-GPOE-PSO______NNN.gci 8P-GPOE-PSO______NNN+1.gci
+```
+
+This will read out the data, parse and validate the quest information and save the raw (compressed) `.bin` and `.dat` 
+file using a filename automatically derived from the quest's ID number.
+
+Or, you can provide your own `.bin` and `.dat` filenames if you wish:
+
+```text
+gci_extract 8P-GPOE-PSO______NNN.gci 8P-GPOE-PSO______NNN+1.gci myquest.bin myquest.dat
+```

+# PSO Ep 1 & 2 (Gamecube) .qst Header Generator Tool
+
+This is a simple tool that can generate quest `.qst` file headers for a given set of `.bin` and `.dat` files. This tool
+was written to complement Sylverant's [qst_tool](https://github.com/Sylverant/pso_tools/tree/master/qst_tool) which
+has primitive support for automatically generating a `.qst` file header if one is not provided.
+
+**This tool is NOT required if you are using the "bindat_to_gcdl" tool also included in this repository. That tool
+automatically generates the necessary header information in an identical manner to how this tool does.**
+
+## Usage
+
+Given two quest `.bin` and `.dat` files ...
+
+```
+gen_qst_header quest.bin quest.dat
+```
+
+Will result in the `.bin` file's header information being saved to a file called `quest.bin.hdr` and the `.dat` file's
+header information being saved to a file called `quest.dat.hdr`.
+
+This can then be used with "qst_tool" to generate a `.qst` file if you wish:
+
+```
+qst_tool -m gc quest.bin quest.dat quest.bin.hdr quest.dat.hdr
+```
