SA Intended Cheat codes

Nixixix:
Hidden below is my current list of all cheats: effects, hashes, shortest codes (A-Z0-9), most likely intended codes.

The descriptions and previously known codes are from http://www.gtasanandreas.net/cheats/pc.php with some corrections: BMTPWHR is "Recruit Anyone (AK-47)", not "Country Vehicles and Peds, Get Born 2 Truck Outfit"; they are also missing the never hungry and mega-punch cheats as well as the disabled ones (obviously).

he list is in the same order as the hashes are in the exe (reverse byte order: 12345678 = 78 56 34 12 in the file). The cheats with no codes listed can't be activated without editing the game (see my previous post). * in the best known code means that I'm not convinced it's the intended one; ** certainly aren't, and the rancher cheat most likely doesn't have any intended code.

New likely intended codes I've found since my last post:

BetterStayIndoors = BIFBUZZ = Gangs Control the Streets
DullDullDay = ALNSFMZO = Overcast Weather
IAmNeverHungry = TransitionOffScreen = Never Get Hungry
ICanGoAllNight = VKYPQCF = Max Stamina
IDoAsIPlease = AEZAKMI = Never Wanted
INeedSomeHelp = HESOYAM = Health, Armor, $250k
IWantToHover = KGGGDKP = Spawn Vortex Hovercraft
LoveConquersAll = BEKKNQV = Slut Magnet
OtherGangsCourses = OUIQDMW = Free Aim While Driving
SandInMyEars = CWJXUOC = Sandstorm
StingLikeABee = CrookOperated = Mega Punch
TimeJustFliesBy = YSOHNUL = Faster Clock

An interesting one is StopPickingOnMe = BAGOWPG = Have a bounty on your head. It's a nice phrase, but the effect is exactly the opposite. Could be intended.

==========previous previosu post =================
Even more off topic: (I'm happy to continue in private.) About finding the originally intended phrases to activate each cheat, well that's a tall order especially if some of them actually are 29 characters long! I mean even if you can enumerate them all fast, how do you automatically guess which one of a huge number of possibilities it is? Who's to say on a glance if FUNDAMENTALRESTACHIEVED (someone died) or BACKROOMRESISTANCE (covert riot) or TESTEDUCATIONALSKILLS like already mentioned, are intended? RECOMMENDEDCHARACTERSATURDAY probably isn't. Maybe if you know the effect of the cheat and have just a handful of these to choose from, but that's not really the case with long codes.


========initial discovery post by tuplanolla=================================
I thought I should mention a few things here before they cause controversy and drama.

The first can of worms is cheats. Some players have accidentally enabled cheats during their runs and blamed the unreliability of the game for it. While the game is indeed rather fickle, it is not the case here as the problem is entirely caused by not understanding the core mechanics of the game. Some luck is also involved, but I would rather avoid the word luck since it has so many interpretations. It is not uncommon to see people mix chaotic and entropic events, but I digress.

The cheat code system is based on weak cryptographic hashes. There are two obvious reasons for that. It prevents players from simply extracting the cheat codes from the game by, say, dumping the data sections of the executable. It also serves as a performance optimization, because inputs are checked each frame and comparing strings of varying lengths is not a fast constant time operation. Keep in mind that the developers sacrificed accurate physics for performance.

The downsides are less obvious, but even more important. The hashes are stored as unsigned 32 bit integers and as such cannot contain all the information in a cheat code. Therefore a single cheat can have many codes. How many depends on the domain size and the quality of the hash function. Since the hash function is optimized for speed, collisions are very likely. Take TESTEDUCATIONALSKILLS, AEZAKMI and IFIRSTDOZ for example; they all have the same effect.

Originally the effects of the cheats were discovered first. It was probably done by checking all call and possibly suitably computed jmp instructions in the input reading loop. Either way it was a simple, albeit tedious, process. The cheat codes themselves were found later. It was done like any other traditional hash cryptography attack: by guessing values from the domain of the hash function, feeding them to the function and hoping the end result is desirable. Cheat codes for most cheats have already been found, but some of them still lack the original form. For example HESOYAM is not a cheat code the developers intended players to use.

If someone wants a fun and easy reverse engineering project, I suggest extracting the hash function from the executable and finding all the original cheat codes with a dictionary attack. The game has lots of plain data files, so the dictionary could be quickly extended and biased for the task.

In conclusion, players actually enabled undiscovered cheat codes. The only way to avoid accidentally doing so is changing the key configuration or avoiding certain movement patterns. The cheat codes to avoid could be extracted from key event logs, if the players had kept them.

My second topic is hardware. It is easy to obtain a perfectly normal sound card and configure it to serve as a null sink. Such a device consumes all audio samples at an indefinitely high speed and effectively skips all events that are synchronized to playing dialog or other sound files.

It is similarly effortless to set up a graphics device with a configurable frame rate or a file system with different scheduling. Some players already use third party frame limiters and memory mapped files to do that.

Why stop there? More speed can be gained by using suitable hardware. An argument about fairness could be raised, but that applies to every trick in the book and is really not my concern. The computer has the final say on the rules in any case.

My last note is one of project management. The game, like most games, is too vast for a single person to handle. Every player using outdated routes in certain places is a manifestation of that. A community effort is needed if a rigorous result is desired. I suggest setting up a repository for what software projects call a reference implementation. It would be a collection of every route through every mission and every mission transition. Faster or safer routes whould obsolete slower or more dangerous ones, but nothing would be deleted or forgotten. Both Wikipedia and TASVideos use such a version control policy and it works well.
