Comments/Requests/Bug Reports/etc are welcome!

NOTE: This is a public beta, and as such it is crucial that you backup all files you save/rebuild with SparkIV! I won't be held responsible for any loss of files/limbs/cake/etc that may result due to the use of SparkIV.

- Saves/Rebuilds IMGs. Saving RPFs is currently not supported, but will be added eventually.
- Allows you to import/export files. 

Requirements
- Microsoft .NET Framework 3.5. If SparkIV does not run, you need to download and install this from here.
- Version 1.0, 1.01 or 1.02 of GTAIV.exe. This is required for the cryptographic keys.

Resource Files
Exported Resource files will be exported as-is and compressed. To extract the data segments out of the resource file, a tool called Resoursaur (yes, creative... aren't I? ) is available in versions of Spark 0.5.4 and older (download available at the Google code link). This tool will be quite useful to those wishing to explore the resource file formats in a hex editor.

Legal Issues
A cryptographic encryption key is required for running SparkIV. For legal reasons (DMCA/EUCD/etc), this key is not included in SparkIV but rather extracted from GTAIV.exe on startup. So, you will need a supported version of GTAIV installed, or have a GTAIV.exe placed in the same directory as SparkIV.
