GitHub - MitchellSternke/SuperMarioBros-C: An attempt to translate the original Super Mario Bros. for the NES to readable C/C++
"An attempt to translate the original Super Mario Bros. for the NES to readable C/C++.

I've taken the smbdis.asm disassembly of Super Mario Bros. and successfully converted it to C++ using an automated codegen program I wrote (which you can be found in the codegen/ subdirectory of the repo). Right now, it looks very similar to the original disassembly and is fairly dense code, but it works! Check out source/SMB/SMB.cpp if you're curious."

GitHub - n64decomp/sm64: A Super Mario 64 decompilation, brought to you by a bunch of clever folks.
"This repo contains a full decompilation of Super Mario 64 (J) and (U). The source and data have been decompiled but complete naming and documentation all of the code and data is still a work in progress. Decompiling the (E) ROM is also an ongoing effort."

Unravelling Konami's Arcade DRM
"I’ll be focusing on two things for this adventure - my process in reversing the encryption, because by sharing my methods I may help others. Secondly, high level details of Konami’s dongle-based encryption, because it’s rare to find proper information on actual, in-the-wild implementations of USB dongle based security."

Exposing NSDictionary - Bartosz Ciechanowski
"NSDictionary doesn’t make any promise of its internal implementation. It would make little sense for a dictionary to store its data in a completely random fashion. However, this assumption doesn’t answer the key question: does NSDictionary make use of a hash table? This is what I’ve decided to investigate."

Exposing NSMutableArray - Bartosz Ciechanowski
"This is fantastic news! It means that __NSArrayM can be processed from either side. You can use __NSArrayM as either stack or queue without any performance hits."

DONHODGES.COM - DEFENDER'S EXTRA LIFE BONANZA AT 990,000 POINTS EXPLAINED
"If a very skilled player manages to reach 990,000 points in the 1980 video game, Defender, the game begins to award extra ships and smart bombs at an incredible rate.  This occurs due to a bug in the algorithm that awards extra lives and smart bombs.  Here we will dissect the algorithm to explain why this behavior occurs."

DONHODGES.COM - MS. PAC-MAN BLUE MAZE BUG FIXED
"Recently I received a request from a visitor to this web site to look into the so-called "blue maze bug" that affects Ms. Pac-Man.  It is well known that if a credit is inserted at the very beginning of the attract mode, before the red ghost appears under the marquee, the first maze of the game will be colored blue instead of the normal maze color."

An Anti-Reverse Engineering Guide - CodeProject®
"In this article, I plan to travel a bit deeper into the interesting world of reverse engineering and explore some more intermediate level techniques for annoying reverse engineers. Some comments in my previous article noted that the techniques I presented could, and are most of the time, easily bypassed by intermediate level reversers"

"It took multiple years, lots of money, and the help of a vast number of individuals; but we've finally pulled it off: every SNES DSP program has now been extracted and emulated fully."

How to crack a Pacman Plus!

Toad Houses Disassembled - Programming stuff
"What item you receive is determined only after you open a box. So, in fact only the box you open is filled. The other two boxes are never touched. They are total smoke screens whose only purpose is to fool the player into believing he actually takes part in the decision what item to receive."

Synalyze It! Reverse Engineering and Binary File Analysis made easy
"Imagine ... you got a binary file and don't know its contents. Or some software creates binary files where you have a specification but don't want to decode them manually. Synalyze It! allows you to create a grammar for binary files interactively. Unlike in regular hex editors or viewers the files are interpreted automatically for you!"

Reverse engineering Apple's OS X • The Register
"A number of folks have asked me what tools and techniques I use to reverse engineer Cocoa executables. I thought it would be worth taking some time out from documenting undocumented APIs to show you how easy it is to do the same thing for yourself."
