ReferenceError: Can't find variable: dcodeIO

[mgoodings]

This issue may just be specific to my console, it's never been online and I'm currently running it through the User Guide using a DNS proxy.

I've never been able to get this PoC to run on my 3.55 PS4 up until now, no matter what it always produced the following issue:

Modified arr length = 0x80000000
Found ArrayBufferView in memory!
Modified index is 50
Found modified ArrayBufferView!
!! ERROR: ReferenceError: Can't find variable: dcodeIO
stack: global code@http://manuals.playstation.net/document/gb/ps4/index.html:109:39

I've now found that for whatever reason any globals defined in the first <script> tag will not be available in the global context/window object until the following browser tick. If I move jQuery to first <script> tag it will say $ is undefined, etc.

If I simply create a scripts/dummy.js with an empty global define and include that as the first <script> tag the example will run perfectly fine.

ps4sploit.html

+ <script src="/scripts/dummy.js"></script>
<script src="/scripts/long.js"></script>

scripts/dummy.js

function dummy() {}

Result:

Modified arr length = 0x80000000
Found ArrayBufferView in memory!
Modified index is 50
Found modified ArrayBufferView!
Found modified ArrayBuffer!
