PDF file is also NES ROM that displays its own MD5 hash

Post by Dwedit » Wed May 31, 2017 11:06 am

This is in "International Journal of Proof-of-Concept or Get The F--- Out" 0x14.

Video: https://www.youtube.com/watch?v=h3LWTSzekX0
Website: https://www.alchemistowl.org/pocorgtfo/
PDF file itself: (48.1MB) https://www.alchemistowl.org/pocorgtfo/pocorgtfo14.pdf

There's an iNES header before the PDF header here. It's NROM 32k+8k, and is a simple demo program that displays a screen of text, plays music, and has a hidden movable character if you press start.

PDF file seems to be an article about hacking and stuff, and states its own MD5 hash several times in the text.

I also attached just the 40K NROM file itself, not the 48.1MB PDF file. This is not my work at all.

This reminds me of the combination SNES/Genesis ROM packed in a PDF. Can't find the original article about it, but I do still have the PDF file for it (attached below).

The SNES rom relied on a copier header :(
