You can reverse engineer it yourself by following these steps: type JUM, hold P for a few seconds, type JET and notice that the game is not a teletype terminal.

I don't think you understand. The majority of the time this cheat happens is when you are only holding 1 key for an extended period of time. The place this glitch occurs the most is on the way to Toreno over the bridge. Where you are on a bike holding W and pressing whatever key it is to go lean forward (mine is RMB). What you are saying is from the combination of holding W and pressing RMB I can activate a cheat on a consistent basis.

All we have here is a glitch which I believe you will not be able to reproduce on a consistent basis. If you can I would love to know how since all this glitch does it cost you time.

If that is the case, then an event log or a core dump is needed for reproduction.

Damn you Tuplanolla you nerd-sniper!

Since the game checks string lengths from 6 to 29 and there are 88 hashes matched against, there's roughly a 24*88/2³² ~ 1 in 2 million chance of each new keypress triggering a cheat. (assuming a perfect hash function; don't know exactly in this case) Statistically you do have to mash a lot to hit one by accident but of course there could be particularly easy sequences to hit using regularly used keys.

There are plenty of working combinations for any reasonable set of keys, for example there are 9 different cheats reachable by 14 presses of WSAD (the cutest of them: Aaaa! Dad saw a daw!) and even one with only 12 presses: WWDWASWWDWAS – an unlikely coincidence (!?) that it's a single string repeated twice. The longer you go the more options there are of course. Going with just WAD, the shortest ones are 16 presses, like DDDDDDDAAAAAADWD which is actually reasonably possible to hit accidentally, compared to totally random looking ones.

In Tirean's case something else is happening though, if cheats really activate without pressing anything other than W on the keyboard (or other controllers that produce keypresses) and not even releasing W in the middle. Sounds odd that mouse buttons would interact with the cheat system somehow. You could check if pressing the relevant mouse buttons in the middle of some cheat code stops the cheat from working (still works for me).

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.

For those able to program and interested in finding codes but not in reverse engineering GTA code, here are the technical details (possibly already available somewhere, but I found RE'ing it more fun than googling):

The hash function is a kind of CRC32 – standard polynomial, reverse bit order, pre-inversion AFAICT how they are classified; see below for code. It's applied to the upper case string in 8-bit ASCII in reverse order. For example, "OHDUDE" reverses into "EDUDHO" and the corresponding hash is the CRC32 of that (only the 6 actual characters), which is E958788Ah.

I haven't looked into the exact set of characters possibly included in a code, but at least the letters and numbers are allowed.

The table of hashes is directly readable from gta_sa.exe (at least my version) – search for 7D 23 4B DE in a hex editor and mind the byte order. I haven't tried modifying it (might trigger an integrity check if done bluntly) but it might be possible. Interesting are several occasions of the hash 0. AFAICT only the first match is triggered, and I guess the 0s might all be intended to be disabled, but there are codes that hash to 0 (like K5E65Q) and they do trigger a cheat. Editing the 0 entries in the exe might bring out new cheats and/or horrible crashes. I'd be surprised if nobody had tried that before.

Here's a copy of the table formatted for inclusion in my C++ program:

0xDE4B237D, 0xB22A28D1, 0x5A783FAE, 0xEECCEA2B, 0x42AF1E28, 0x555FC201, 0x2A845345, 0xE1EF01EA, 0x771B83FC, 0x5BF12848, 0x44453A17, 0xFCFF1D08, 0xB69E8532, 0x8B828076, 0xDD6ED9E9, 0xA290FD8C, 0x3484B5A7, 0x43DB914E, 0xDBC0DD65, 0x00000000, 0xD08A30FE, 0x37BF1B4E, 0xB5D40866, 0xE63B0D99, 0x675B8945, 0x4987D5EE, 0x2E8F84E8, 0x1A9AA3D6, 0xE842F3BC, 0x0D5C6A4E, 0x74D4FCB1, 0xB01D13B8, 0x66516EBC, 0x4B137E45, 0x00000000, 0x78520E33, 0x3A577325, 0xD4966D59, 0x5FD1B49D, 0xA7613F99, 0x1792D871, 0xCBC579DF, 0x4FEDCCFF, 0x44B34866, 0x2EF877DB, 0x2781E797, 0x2BC1A045, 0xB2AFE368, 0xFA8DD45B, 0x8DED75BD, 0x1A5526BC, 0xA48A770B, 0xB07D3B32, 0x80C1E54B, 0x5DAD0087, 0x7F80B950, 0x6C0FA650, 0xF46F2FA4, 0x70164385, 0x00000000, 0x885D0B50, 0x151BDCB3, 0xADFA640A, 0xE57F96CE, 0x040CF761, 0xE1B33EB9, 0xFEDA77F7, 0x8CA870DD, 0x9A629401, 0xF53EF5A5, 0xF2AA0C1D, 0xF36345A8, 0x8990D5E1, 0xB7013B1B, 0xCAEC94EE, 0x31F0C3CC, 0xB3B3E72A, 0xC25CDBFF, 0xD5CF4EFF, 0x680416B1, 0xCF5FDA18, 0xF01286E9, 0xA841CC0A, 0x31EA09CF, 0xE958788A, 0x02C83A7C, 0xE49C3ED4, 0x171BA8CC, 0x86988DAE, 0x2BDD2FA1, 0x00000000, 0x00000000

Here's a simple implementation of the hash routine including the string reversal; the game and my actual code use a lookup table to replace the b loop which is moderately faster.

Code:

typedef uint32_t Hash;
Hash slowHash(const string& s) {
    Hash hash = 0xFFFFFFFF;
    for (int i = s.length() - 1; i >= 0; --i) {
        hash ^= s[i];
        for (int b = 0; b < 8; ++b) {
            if (hash & 1)
                hash = (hash >> 1) ^ 0xEDB88320;
            else
                hash >>= 1;
        }
    }
    return hash;
}

The shortest codes (using letters and numbers) for each cheat, in case someone is interested:

It is delightful to see research getting done.

Finding longer cheat codes with brute force is of course impossible, but using a rainbow table might be worth a try. The most likely words and phrases should be common or relate to the game. Free (libre) dictionaries are easy to find and game dialogue can be extracted from text/american.gxt.

I went back and watched one of the VOD's where Tirean activated a cheat: http://www.twitch.tv/tirean/c/3078843

In this video he activated the DDDDDDDAAAAAADWD cheat. He was turning to the right along the train tracks and once the curve ended, he started adjusting his position by going left. At the end the cheat ends up activating because he readjusted to the right, and then let go of W (to check something in his splits), accelerated again and went right again.

I think you just need to be more careful with the keypresses from now on. May also be worth noting that DDDDDDDAAAAAADWD and WWDWASWWDWAS are both weather cheats (sunny and foggy respectively) and AAAADADSAWADAW is a quadbike cheat (Didn't someone claim to spawn a quadbike with a random cheat before?)

Great! Inspired by that success, I looked for longer "easy" sequences like that, and it turns out that that one is so much simpler than all the alternatives, that it could well be the only one that has randomly triggered more than once in a speedrun so far.

I assigned complexity points like this: A/D = 1 point, transition from A to D or D to A (ignoring W/S) = additional 2 points, W = 8 points, S = 12 points. DDDDDDDAAAAAADWD scores 27 with 7 Ds (7), A (3), 5 more As (5), D (3), W (8), D (1). The next least complex sequences are 43 points: DDDDDDDAAAAAADDDADDDDADAAAD and DDDDDAAAAADDDAAAADDDAAWD and many more sequences from that score onwards.

I was lucky to spot the easy sequence the first time. If it had one more repeated A or D it wouldn't have been much more complex but it would not have been among the shortest codes.

A simple but annoying solution for those afraid of D⁷A⁶DWD: move your controls. Using EDSF instead of WSAD makes the least complex cheat FFFFSSFFFEFFFSSFFSSSF at 40 points (RFDG: 37). Using the arrow keys would make it impossible to trigger cheats by moving (I imagine) but that sucks...

an alternative to that, though maybe tiring, is to use sharpkeys to rebind your keys so that wasd = esdf, and unbind it once done playing, so you don't have to get used to a new button setup
http://sharpkeys.codeplex.com/
an even better alternative is to make an autohotkey script that does the same thing that you can run when you play

What a coincidence.
I just deactivated the relevant Sharp Keys entry (swapping a letter button and a non-letter button) because I count it as cheating in light of the new knowledge.

I use the mouse wheel for small left/right adjustments (I set it up this way in order to stay in the middle of the road when camera twitching), so just do that and you won't ever get a key press rate big enough. I still need to practise mouse button mashing while wheel-rolling, though.^^

The cheat video: If that happened to me, I would think "I just pressed W" while playing and when re-watching, simply because without this new knowledge, minor key presses (micro-adjustments) is just irrelevant information that goes unnoticed or forgotten. IIRC, I had to look a bit closely to see (and not immediately forget) how many button presses these were even knowing what was happening. The burden of proof is on Tirean's side now, I think.

What are the easiest cheats sequences and cheats do they activate with ZQSD ( standard french keyboard) ?
Also could someone please release the full list of all the cheats sequences so we can check these thing manually and rebind our keyboards if needed, Thank you in advance

dareka: The most likely cheat with ZSQD is QQZDDDDQZDDQQQ (spawn monster truck) at 36 points. Not as bad as D⁷A⁶DWD but not impossible either. The next one is 44 points.

There's no "full list of all the cheat sequences" because there's a practically infinite number of them. Even 6-character sequences are a long list and each added character roughly multiplies the count by 36 (using A-Z0-9), all the way up to 29 characters long.

I took a look at what keys the game counts for the codes: Exactly all the keys with printable characters (including space, not backspace/tab/return) in the main part of the keyboard are in, numpad isn't. The character each key is counted as depends on the selected layout, but modifiers like shift are ignored. Don't know what happens if the layout contains characters that don't fit in 8 bits. If they are ignored, it might help to switch to a non-latin layout.

Off topic: More and less probably (mostly less) originally intended cheat codes for every cheat, and some related information. DICKJUSTSAYING or FRIENDTONGUESERVICES intended codes? You decide...

Like I already said, finding all the actual original codes is impossible ultimately because there's no way of weighting the search so that you don't get a million more likely-looking entries before the hardest intended code, if it's sufficiently odd and long. (at least likely-looking to the weighting function even if not a human reader who knows the effect of the cheat)

Still, I had fun improving my previous super-simple dictionary attack with a huge dictionary with word frequency data from Google ngrams. (the smallest set, the English One Million 1-grams, >1G download...; weighted to favor recent years) I didn't bother including anything from the GTA texts.

I found a likelyhood treshold that left at least 5 entries for each cheat, then went through the list by hand leaving only those that could be interpreted to make the most sense, ignoring what the cheat does. I left in some funny ones even for cheats that already have a very likely intended code.

I also loaded the list of codes from http://www.gtasanandreas.net/cheats/pc.php to find the effects of each cheat (descriptions © them) and see which intended codes are already known. Guess there are other known ones not listed there, but w/e. I left out the known codes to clean the list up, but only about 80% of them were found with my dictionary and weighting, the rest being buried under "better" choices. Interestingly, that site doesn't list the cheats activated by CROOKOPERATED and TRANSITIONOFFSCREEN. Maybe they don't actually do anything beside print "cheat [de]activated" or nobody could figure out what?

dareka: The most likely cheat with ZSQD is QQZDDDDQZDDQQQ (spawn monster truck) at 36 points. Not as bad as D⁷A⁶DWD but not impossible either. The next one is 44 points.

There's no "full list of all the cheat sequences" because there's a practically infinite number of them. Even 6-character sequences are a long list and each added character roughly multiplies the count by 36 (using A-Z0-9), all the way up to 29 characters long.

I took a look at what keys the game counts for the codes: Exactly all the keys with printable characters (including space, not backspace/tab/return) in the main part of the keyboard are in, numpad isn't. The character each key is counted as depends on the selected layout, but modifiers like shift are ignored. Don't know what happens if the layout contains characters that don't fit in 8 bits. If they are ignored, it might help to switch to a non-latin layout.

Off topic: More and less probably (mostly less) originally intended cheat codes for every cheat, and some related information. DICKJUSTSAYING or FRIENDTONGUESERVICES intended codes? You decide...

[hidden]Like I already said, finding all the actual original codes is impossible ultimately because there's no way of weighting the search so that you don't get a million more likely-looking entries before the hardest intended code, if it's sufficiently odd and long. (at least likely-looking to the weighting function even if not a human reader who knows the effect of the cheat)

Still, I had fun improving my previous super-simple dictionary attack with a huge dictionary with word frequency data from [url=https://books.google.com/ngrams]Google ngrams[/url]. (the smallest set, the English One Million 1-grams, >1G download...; weighted to favor recent years) I didn't bother including anything from the GTA texts.

I found a likelyhood treshold that left at least 5 entries for each cheat, then went through the list by hand leaving only those that could be interpreted to make the most sense, ignoring what the cheat does. I left in some funny ones even for cheats that already have a very likely intended code.

I also loaded the list of codes from [url]http://www.gtasanandreas.net/cheats/pc.php[/url] to find the effects of each cheat (descriptions © them) and see which intended codes are already known. Guess there are other known ones not listed there, but w/e. I left out the known codes to clean the list up, but only about 80% of them were found with my dictionary and weighting, the rest being buried under "better" choices. Interestingly, that site doesn't list the cheats activated by CROOKOPERATED and TRANSITIONOFFSCREEN. Maybe they don't actually do anything beside print "cheat [de]activated" or nobody could figure out what?

Most plausible new codes to replace non-word codes on the previously mentioned list:

SOLONGASITSBLACK = IOWDLAC = Black traffic
NUTTERSTOYS = UZUMYMW = Weapon Set 3, Nutter Tools

It is possible to get a sub 45 RTLS any% based on this. Anyone aiming for a sub 5:15 any% should be able to pull off at least a sub 48. This is a few minutes faster than the top runners' best times despite a few silly mistakes. My vertical bird was nearly perfect here; it is at least 10 seconds than that of the average time. There are a few risky strats that I do, such as the ones during Grove 4 Life that save a few seconds.

I also found out that you can bail out of the helicopter during Meat Business without losing it as long as you manage to land it inside the compound. The game will reposition your helicopter once you exit the factory.

Apart from some driving routes I have to test this looks pretty much how it should be done

i dont know how to start this shit

1)well if u move ESC key to good location u can do this

2) it best works with "start->control panel-> keybord" max speed on keypress related things

The 45 minute RtLS can be improved by over 40 seconds if you get perfect RNG with the 3rd wave skip(which no one uses, but it does rely on RNG).
That driving route after Los Desperados is probably not the fastest. I am not sure what route is the fastest there.

Here are the fastest ways that I've found of doing Grove 4 Life.

Can anyone explain what happened here?
It can be useful if you manage to teleport across the map. But I doubt that is possible.

i think it has something to do with the fact that u were lying under bike(for short period) and game assumed u wont be able to stand up

Regarding the cheat codes... instead of sweating with trying not to activate them can't you just make a patch and deavtivate them ? I'm not a great hacker/RE and i don't know how hard it is with SA but i did it some time ago in GTA3....

That would be modifying the game which is not allowed.

It you are really worried about causing the cheat code just press Q and E after you pressed A or D a lot. That is what I have been doing lately.

I do not see how input like
AAAAADADSAWADAW is more likely to trigger a cheat than
AAAAADADSAWADQE
The only thing 'special' about wsad is that they are used often, so using a 'non-special key' like q (or q&e) probably does not help. It's not that each key has a 'likelyhood' of being part of a 'cheat'. In other words: from the myriads of possible cheats, there are probably just as many (few) cheats with the properties:
a bit of w/s, a lot of a/d as with
a bit of w/s, a lot of a/d, some q&e in between
This is a bit simplified but should do.^^

It's possible that there is a 'magic sequence', so for explanatory purposes, let's say it's 'qqee': then there is no 'cheat code' with 'qqee' in it (or - better than nothing and much, much more likely - it 'just' vastly increases Nixixix' 'unlikelyhood value')
This can only be checked by modifying Nixixix' program.
