=== MultiEx BMS Script === 

Not written yet.

=== QuickBMS Script === 

* [https://github.com/bartlomiejduda/Tools/blob/master/NEW%20Tools/Insane%201nsane/Insane_IDF_script.bms Insane_IDF_script.bms]

=== Notes and Comments === 

* Table of Content (archive footer) is encrypted with '''XOR''' encryption. TOC offset is XORed with 0x123.
* Data seems to be unencrypted and uncompressed.
* IDF extension is probably translated to "Insane Data File".

=== Encryption Method ===

Below is example of the code from quickbms script which may be used to decrypt TOC:
<div class="toccolours mw-collapsible" id="mw-customcollapsible-myDivision" style="width:800px; overflow:auto;">
<pre>
for i = 0 < TOC_LENGTH
	get NEW_BYTE byte
	XMATH NEW_BYTE "NEW_BYTE ^ TOC_XOR_KEY"
	XMATH TOC_XOR_KEY "(NEW_BYTE + i + (TOC_XOR_KEY * 5)) & 0xFF" 
</pre>
</div>
