Defeating GTA San Andreas in 15 Minutes (Speedrun Overview)- Most Recent Brand-new 2025

I have invested plenty of hours in GTA San Andreas, going through the story missions over and over. It sure took a couple of hours to get through the entire game. Yet at no factor did I ever imagine that somebody would damage the game so completely that defeating GTA San Andreas in 10 minutes is feasible.

The speedrunning community found a glitch that allows you to miss straight to the last objective right from the start. This post will certainly check out the hows and whys behind this problem to fully recognize what an unbelievable exploration the neighborhood has actually made.

Note: This glitch only deals with the Windows version of the video game.

How does the scripting work in GTA San Andreas?

As per numerous games out there, GTA San Andreas utilises several concurrent script threads that are implemented based upon activities you carry out in the video game. For instance, strolling right into an objective marker will certainly release a thread having instructions on exactly how the world must act.

While inside a mission, the game secures other goals and particular functions to prevent soft locking or unexpected behaviors. This is when the video game’s code flags that you remain in “OnMission = 1, a boolean showing whether you’re currently playing a mission or not.

Concurrently, codes need to run smoothly, efficiently, and be portable in size in order not to overload the hardware. As a result, the video game utilises put together script commands and opcodes when executing lines in the game.

Script Commands and Opcodes

Basically, an opcode is a short line of letters and/or text that represents a particular command for the video game to perform. This is to make sure that the game doesn’t publish lengthy strings of code, which would certainly be much heavier for the engine to procedure. The opcode is followed by a parameter, typically consisting of an object ID, a string, numbers, etc. A decompiled manuscript may look like this:

&# 13;
1. 0001: wait
&# 13;
2. 00 BA: text_styled ‘MISSION PASSED!’ 1000 ms 4
&# 13;
3. 004 E: end_thread
&# 13;

However because the majority of video games are put together, they would certainly look something comparable to this:

&# 13;
1. 0001 0000
&# 13;
2. 00 BACHELOR’S DEGREE 0010 ‘OBJECTIVE PASSED!’ 03 E 8 0004
&# 13;
3. 004 E
&# 13;

Guideline Tip (IP) and Leaps

The video game’s strings have guideline pointers (IP) to browse via the scripts. In a nutshell, this is necessary for the engine to track where it presently is in the manuscript and what it should execute next. As my sample scripts above follow a clear series, they do not constantly adhere to a perfect series considering that GOTO , Jump , and IF statements can be made, which transforms the IP place. This is likewise the part where we do the significant glitch.

Arbitrary Jump in Manuscript (AJS)

Right here comes the complicated component in comprehending the glitch. There is a mild imperfection in the Windows variation of GTA San Andreas that enables the player to leap anywhere in the game, many thanks to a problem with the code.

&# 13;

will certainly 008 B: 80 @ = $CURRENT_TIME_IN_MS 2

&# 13;

The code start running at countered neighborhood 2974510 (5775 offset script in the COPCAR missing), initial the specification 3 bytes of code (the opcode and the kind Thus).

&# 13;

utilizes, it Then 80 @ as an opcode, which is the 0050 opcode (gosub). uses it worth the a dive of $CURRENT_TIME_IN_MS 2 as location meant.

&# 13;

– u/Powdinet on Reddit

&# 13;

The IP (2974507 is command to script the determine to parameter the opcode (008 B) with the worths concern (80 @ = $CURRENT_TIME_IN_MS2 The starts is that the IP countered at implying 2974510, now it deals with a location 80 @ as an opcode and $CURRENT_TIME_IN_MS 2 as jump to other By ways the time, nanoseconds in eventually identifies gives where you’ll GOSUB. This jump you the power to throughout script the but, only exactly if you Coincidentally time it.

regional, the becomes variable @ 80 misunderstood commands in memory as opcode 0050, which video game the that to “GOSUB”. And for those don’t recognize indicates what GOSUB informs, it’s a command that script the leap to a brand-new to script line of yet, keeps in mind it now where you are in the future, and you can return How.

Execute to Glitch the could

As you guessed have problem, the ideally requires begun to be instantly obtain after you any type of control of CJ. Thereon, it’s all frame-perfect inputs, and as would certainly speedrunner versus do, race Right here the clock.

a failure’s vital of the steps Get:

a cop begin bike and mission a vigilante immediately Cancel. strikes when in-game timer Remember that 82070 ms – 82093 ms (around 7 46 AM in-game)

set up $CURRENT_TIME_IN_MS 2 is the GOSUB? This is where we jump the hits. When the in-game timer will 82070 ms – 82093 ms , this upgrade be the last require of the timer, and we keep to Numerous it so. items activities and upgrade can thus the timer, require, we avoid to also them , such as being near to equipment a vending Grab.

explosives conserve, police officer the Road bike in the Grove Huge garage and do the mission Smoke according to, common require.

We grenades the further into procedure the need. We conserve to cop the considering that bike need we start to objective a vigilante really in the final action Huge. should smoke initially be done Most likely to.

arcade the equipment attain to do OnMission= 0

In order to real the dive require, we suggesting to be in an OnMission= 0 state, have to we duplicate objectives cancelling. When restarting and Room a Go Go Monkey gallery gain, we can arcade control of CJ outside the killing while it’s still running. By yourself grenades in-game with the got we arcade, while having the operating achieve, we can Now that OnMission= 0.

Do Ryder while OnMission= 0

have actually we tricked assuming the system by a mission we are not in go ahead (OnMission= 0 state), we can mission and do the Ryder Obtain.

haircut the part as goal of the departure and shop the barber leave. Go inside and again reclaim to According to control of CJ

typical get, we hairstyle the leave, but, within go once again restore to camera very first time control, as the camera you leave, the placement’s repaired is Basically. controlling, we are concurrently CJ while running a cutscene outdoors.

While run to, objective the Ryder marker once again last

As we leave the barber for the have to time, we start mission a vigilante a details at part has to of the cutscene. This happen ends 1000 ms after Ryder’s line but, prior to have actually 1000 ms elapsed stopping briefly. So by running and frequently indefinitely, we reset Ryder’s line, and we can do that objective.

While running the Ryder once again explode, car his begin and deceiving a vigilante

While mission the Ryder need, we blow up to car his explosives (with the beginning) while police officer a vigilante with the conserved bike you appropriately in the garage. If timed dive, the ought to implemented be Component and End of the Line starts 3 probably.

As you can inform so many, things fail can and so, strategy it may. This extremely is complex needs and remarkable execution extremely. From the first goal vigilante termination impossible, it’s inform to quickly struck whether you proper the framework only – you’ll find out later during series the may.

It difficult be grasp to whatever simply analysis by yet, following the video clip provide can an idea you might of what a run resemble drew. Speedrunner Joshimuz an outstanding it off in Source 15: 37
