== Notes on specific editions ==
=== Sold Out Software ===
Dumpers will occasionally mistakenly add e.g. "SOV. 2.5.4" to either the serial or version fields. This should be removed, as this is an internal publisher reference and is not a serial nor does it relate to the true version number of the software.

== Notes on specific copy protections ==
=== CodeLock / CodeLok / CopyLok ===

Due to a known bug in the Plextor firmware, any dump of these discs made using a Plextor and any tool is likely to be bad. It incorrectly reports the total number of errors, usually multiplying this by 2 or 3 times.

For example, when dumping https://redump.info/disc/53929/ with either DIC or redumper and a Plextor drive, the error count is incorrectly reported as 1516, exactly double the correct 758 errors

An incorrect _c2Error log looks as follows:
<code><br/>
LBA[002312, 0x00908] Detected C2 error 380 bit<br/>
LBA[002313, 0x00909] Detected C2 error 20 bit</code>

A correct _c2Error log looks as follows:
<code><br/>
LBA[002312, 0x00908] Detected C2 error 300 bit<br/>
LBA[002322, 0x00912] Detected C2 error 300 bit</code>

These discs can be correctly dumped using a non-Plextor drive and any of the following tools:
* DIC (using an ASUS or compatible firmware drive)
* redumper
* CloneCD (note: may require fixing with CDMage and manual replacement of error sectors with 0x55)
