This guide contains documentation on how to write patches in pnach files.
== Pnach Format ==
A pnach file is a sequence of patches in the following format:
<pre>
patch=1,EE,00000000,extended,00000000
</pre>
For example, this patch writes the 4-byte value 0x64 to the address 123456:
<pre>
20123456 00000064
</pre>
and in pnach format it becomes:
<pre>
patch=1,EE,20123456,extended,00000064
</pre>
Below is the documentation of all pnach codes.
