This post will describe all KNOWN differences between various versions of the game, based on the perspective of the US/EU PSP version since most runs currently are designed/tested/done on this version, and the emulator version strives to achieve parity to it.

Positive changes are listed with +, negative - and neutral •

Basic

• Vic takes 1/2-1/3 damage from almost all sources (Good dying less, bad for death warps)

- When an NPC dies it cancels your lock on, meaning you constantly have to re-aim in order to switch targets after someone dies.

- NPCs on the ground are untargetable, so if one gets knocked over you cannot aim at them

- Analogue sensitivity is increased, making small movements harder and reaching the maximum input faster

• Yes and No are swapped in menus

+ Pager is faster due to Japanese text

• The downtown Mac 9 Rampage was moved North of it's position on EU/NA

+ Weapons are correctly respawned in "Burning Bridges"

Technical

• Uses updated/different SCMs (If you don't know what this means don't worry about it)

+ Snitch Hitch Dupe is possible only on this version (that we know of)

+ Got Protection dupe doesn't crash if no Save n' Quit between it and Cleaning House Dupe

Route (as of 01/09/2020)

• Assassins in "Soldier" do not damage you. Instead set the car on fire and get in it before it explodes to death warp.

+ Dupe Snitch Hitch to skip Zero to Hero

+ Save n' Quit after Truck Stop, instead of after Cholo Victory and Hose the Hoes

Note: Because Emulator is trying to be the same as Real Hardware, and Emulator is not an official release, anything proven only to work on Emulator and not Real Hardware is not allowed.

Basic

+ Load times are faster (unless your PC loads slower than a console from 2004)

+ Frame rate is locked to a stable 30 (again; unless PC bad)

+ More Stable after duping, meaning less Save n' Quits between dupes

- Need to reverse in the Hovercraft before you can accelerate, most notably in "White Lies" (Emulator bug?)

Technical

- Lots of stuff! (Allan please add details) however none of it is allowed since Emu is trying to be real PSP and Emu is not an official version

Route (as of 18/01/2019)

- Duping "The Colonel's Coke" has a higher chance of unusable Helicopter spawns. If not done (So "Kill Phil: Part 1" is done) you will not be in a good spot to setup om0 Rampage carry through for "Home's On The Range" so instead do "Unfriendly Competition" dupe after "Hostile Takeover" (like PSP runs pre-dating 2019).

The PS2 version was released after the PSP version, and features some changes and additional content. [Click me for a map of all PS2 exclusive content](http://www.ehgames.com/gta/map/ob2k0gwtoge)

Basic

- Load times are slower from disc (PS2/PS3)

- Load times are slower from HDD??? (PS3)

- Frame rate is worse (PS3 does a poor job of emulating PS2)

+ More Rampages, most notably the one on Prawn Island

+ More Vehicle spawns and purchase spots, most notably the PCJ in Vice Port and Skimmer south of Ocean Beach

• More Unique Stunt Jumps

+ Better Controls (Right Analogue Stick input, more shoulder buttons)

- Planes instantly explode when crashed (like in GTA:SA)

• The downtown Mac 9 Rampage was moved North of it's position on PSP

Technical

• Probably uses updated/different SCMs (If you don't know what this means don't worry about it)

+ Changing language while a Pager is on screen skips it

- Going Out of Bounds does not flip every vehicle

- Repeating "Hose the Hoes" om0 4 times crashes (requires Save n' Quit)

+ Garages don't fail to store vehicles

Route (as of 18/01/2019, only basic suggestions or required changes)

• Assassins in "Soldier" do not damage you. Instead set the car on fire and get in it before it explodes to death warp.

- Do "Waking Up The Neighbours" once while om1 as per pre OOB strats (PSP runs pre-dating 2019). This will include not setting up om0 rampage before and during "Fear the Repo", and instead doing it before and during "When Funday Comes".

- Save n' Quit during "Hose the Hoes" om0 passing

+ Consider using the Skimmer near Lance's House for travelling to missions on Prawn Island, eg: "Blitzkrieg" -> "The Mugshot Longshot" or "Say Cheese" -> "Kill Phil: Part 2". However I don't know of anyone timing these. Perhaps even a mission order change would be beneficial like "White Lies" -> Skimmer -> "Say Cheese" -> "Where It Hurts the Most" -> "Kill Phil: Part 2"

+ Use "Coach Tour" Submission and Prawn Island Rocket Launcher Rampage to duplicate "So Long Schlong" after "Domo Arigato Domestoboto"

¯\_(ツ)_/¯ Just use PSP Emulator please
