Taxi Driver Instapass with Farewell to Arms (PSP JP & PS2). You'll need molotovs and some heavy weapons (better to have rocket launcher and any automatic weapon). Credits to dynamicearth78 on ds.

Setup:

• Make your health as low as possible (f.e. blowing molotov in front of Vic's face + set ys on fire 2 times).

• Park any vehicle near the spot where padlock will warp you to -set up om0 rampage with padlock and go to the Diaz (hold x). you shouldn't get in other vehicles besides your police bike you set all that stuff up with to prevent the parked vehicle from despawning.

• Release x, walk into Diaz 's marker and press and hold O when rampage timer will be around 2-3 seconds).

• During cutscene wait until camera view changes to Diaz and release O to warp, after which Vic will be in walking animation. to get rid of it get in and get out of your parked vehicle. then go to closest wall, prepare molotovs and wait until Diaz's last cutscene line ends.

• press and hold O as fast as screen begin to fade so Vic will throw molotov (hope that you will not be trolled by the game and molotov will actually explode instead of bouncing out or fall out of bounds. there better be some place between Vic and the wall to increase chances of successfull deathwarp) and if you 'll have little amount if health Vic will be dead during next mini cutscene where Gonzales enters the truck.

• Press x when screen begins to turn white. If everything will be done correctly you will be able to progress the mission without Vic being "glued" to helicopter om0.

• Buy your weapons back and steal the taxi in front of the hospital. Go to the place where truck will be ambushed.

• Wait until ambush and destroy all of the enemies ASAP, then go to the barricade on taxi you've stolen and destroy it by being close to Sunshine Autos. Go to the SA fast, park your taxi close to the spot after padlock warp, pick any padlock and hold O. i'm not sure but i'd recommend to not to look at the direction of the truck much to prevent it from being destroyed by puirsuiting enemies.-wait until next fade without skiping the cutscene. if you are good that fade will longs forever and your percentage will go up since taxi will be passed, so activate taxi submission ones more to het rid of it and go save. get out of taxi and cancel submission to om0. after that you will have 10 seconds to save until crash due to wrong stack during which submission will be passed another 2 times. So taxi submission passes 3 times overall.

• When screen will start to fade release O to warp, get in the taxi and activate taxi submission.

Firefighter Dupe (PS2 US)

Firefighter X2 (levels are skipped indefinitely. You can complete easily the mission with this). You won't get any monetary reward by duping firefighter.

Takin' Out the White-Trash Partial Skip with Vigilante

The reason it crashes only after a few seconds is because it's waiting for the fading loop to end (it's the loop for the fade out at the end of the cutscene). To avoid the crash you must do the following setup.

Setup:

• Start vigilante.

• Start rampage with vigilante cancel.

• Start vigilante and end the rampage.

• Start vigilante again.

• Start rampage with vigilante cancel.

• Start Takin' Out the White-Trash.

• Progress the mission duped as shown in the original video (get a police vehicle in between).

• Trigger the last cutscene, skip it and start vigilante before the fade out ends.

@inverno Messing with the Man IP also works on International version.

More Instapasses

• King in Exile (Cutscene) Instapass with BMX/NRG-500 Challenge

BMX/NRG-500 Challenge ➜ King in Exile (Useless and softlocks out of progreesion. None Catalina mission is unlocked).

• Las Venturas Gym Moves Instapass with Blood Bowl

Posting all dupes and instapasses known here because is gross having to dig stuff up in Discord and also the Defective Edition is the game without a proper Thread about it until now :). Now we will have everything in one place.

Duping Setups:

• Blood Bowl ➜ Courier ➜ Any mission. Credits to @elNachoLV for the Blood Bowl OM0 setup.

• Kickstart ➜ Vigilante ➜ Death/busted warp ➜ Any mission

• Submissions OM0 setups (Use FPS Cap)

Works like OG Submissions OM0. Just the timining is earlier than the one from Original SanAndreas. Mandupes are the way to go in this version it seems.

Dupes (that are different from OG couterpart and more):

• Drive-By Dupe

Can be duped normally and skips Sweet's Girl. Also with Vigilante you can triple Drive-By (Vigilante stack restarts the mission when finishing the first two, given 3 completitions).

• Jizzy (Cutscene) Dupe

Jizzy (Cutscene) when duped it just Instapass Jizzy (Mission) (it's not stuck one instance like OG).

• Ryder Triplication

Same case as Drive-By. Vigilante stack just restarts the mission after passing the first two given 3 completitions (No softlocking out of progression due to first 2 instances being passed before the start of the third one).

• Gray Imports Triplication

Same case as Drive-By and Ryder.

• Wrong Side of the Tracks Triplication

Same case than the other two but with BMX/NRG-500 Challenge .

• Los Sepulcros Triplication (Dupe)

Again BMX/NRG-500 Challenge is used to restart the mission by stack, but in this case Los Sepulcros dupe will always fails an instance afer finishing the mission so while doing this setup you pass 2 Los Sepulcros Instances (one finishes normally, one fails because the dupe and the last one by stack instantly passes. Useless, softlocks out of progression. You need to do Reuniting the Families to unlock Green Sabre).

Duping Setups and routes:

• A Home in the Hills Dupe

A Home in the Hills is a mission which needs to be started in an interior world. And becasue of this and becasue we don't know how to hold calls in this version (yet), you can dupe this mission by using another mission. There are two known ways.

Pimping ➜ A Home in the Hills

Kickstart ➜ A Home in the Hills

• Home Invasion ➜ Catalyst (Optimization)

Because of the requiered mandupes in order to dupe faster in this version we could just dupe Catalyst with a Taxi after Home Invasion.

• Loco Syndicate and Woozie ➜ Outrider

T-Bone Mendez and Mountain Cloud Boys can be dupe as normal (recommended because in this version 0* Glitch is not only slower it is also easy to loose when the accuracy of the NPCs is increased). Also Lure can be duped in this version. Skips Amphibious Assault (swimming which is really cancer in this version). Found by @GoingHam.

• Monster ➜ Learning to Fly

You can dupe Highjack and Verdant Meadows like this.

• Misappropriation ➜ Saint Mark Bistro

You can dupe Misappropriation and Black Project like this.

• Beat Down on B Dup ➜ End of the Line

You can dupe Beat Down on B Dup in this version (reload autosave becasue none peds will spawn after the dupe, so you reload the autosave and you have the mission dupe and also peds spawnning normal). Also you can dupe Riot. Tried to dupe Los Desperados to skip Gang Territories but when you dupe the mission one instance fails when you finish it.

• Go to the PCJ located near to the mall while waiting for the Rampage timer to expire following the driving route in the video.
• Get on the PCJ (doesn't matter if Lance goes with you).

T-Bone Mendez Instapass with Blood Bowl (leaves one instance. Could be in the interior world or not depending how you do it. Can't be done by normal means. Requieres a mod, no way known to "freeze" the fade. In theory could also be done by normal means but timer is too tight to do. Also could be mass duped with trucking to skip almos everything of SF if a proper setup is found)

Up, Up and Away! Instapass with Black Project (leaves one instance. Can't be done by normal means. Requieres a mod, no way known to start a mission during the fade when going away from Area 69)

Credits to @Patrick_ who found the correct offsets.

Staunton Island 20 Vigilante Kills Instapass with Deal Steal (setup doable for hundo?) Credits: @Powdinet

Setup:

• Start Deal Steal OM0 Rampage.
• Progress the mission until the shooting part.
• Start Vigilante (you ip the 20 vigilante kills for that island).
• Get busted to kill one Vigi instance.
• Start Deal Steal again with the wrong stack instance while having a criminal killed on foot (don't go back to a copcar).
• Finish Deal Steal as the video shows (partial skips fixing the stack. The skip seems broken though).

Phil's Shooting Range Instapass with Jive Drive Works on INTL PSP (Could also intheory works on PS2 too according to Powdinet)

Setup:

• Start Jive Drive
• Progress the mission until the part where you have to kill the cholos and protecting Lance (after the autoscroller part).
• Drive to Phil's Shooting Range and start the mission (make sure that Lance is safe).
• Game will display the results from the Shooting range (passing the mission), then a fade appears and game crashes (has wrong stack tho).

Possible ways to troubleshoot the crash.

• Save before the game actually crashes by warping near a save point (using vehicle purchasing padlock teleport method). In PSP the only "near a doable save point" is Sunshine Autos Quad padlock (which is available after WhenFunDayComes mission) but time is either tight or you can't have enough time to save and reload. Maybe is doable in PS2 by using Sanchez padlock near the first safehouse.
• Stack fix with another mission (which is most probably not feasible).

LS/LV Courier Instapass with Wrong Side of the Tracks

Setup: Start Wsott in the interior world, go to the train part, go away from the train, start courier during the fade before the failling cutscene (before "all you have to do, is to follow the dam train CJ" cutscene)
