NOTE: due to the CEG protection used in P2 (which randomizes certain parts of game code) there's a chance some fixes might not work properly on some systems, I tried to make sure all the patches are generic & use patterns to search for code, but seems there can still be issues for some.
Unfortunately couldn't find much info about removing the CEG on the net, but if you do have issues it may be worth finding a replacement prototype2engine.dll file somewhere.

Changelog:
Spoiler:
Show
1.6:
Added a new PreferLooseFiles setting which gives priority to loose/unpacked files in the game folder over the files inside .rcf packages.
You can now mod the files contained inside .rcf without needing to unpack the whole .rcf first as most mod guides needed you to previously, almost like a mod-loader for the game, should work with majority of files in the game but unsure if it works with all of them, any feedback is appreciated!
1.5.1a:
Fixed crashing when starting new game / playing movies due to wrong binkw32Hooked.dll file being included
1.5.1:
Fixed FOVOffset so that negative offsets can work properly (thanks to kwqweasd for reporting!)
Added FixButtonTapTickRate setting to help fix button-mashing issues when using RemoveTickRateLimit - this helps on P1 but not sure how much it might help P2
1.4:
Added code to automatically disable DPI scaling, hopefully solving any DPI compatibility issues
1.3:
Shadow resolution can be increased from vanilla 2048x2048 up to 8192x8192
Camera FOV can now have an offset applied for increasing/decreasing it as desired
Engines 500FPS hard-cap can now be changed to framerate of your choice, game can run at 1000+FPS if desired, or can be lowered to use it with G-Sync etc
Added settings for changing the default window size when playing with "windowed" launch parameter
Added option to run game in a borderless window (enabled by default), offers a lot of advantages such as faster startup time, less alt-tabbing issues, less frame-tearing...
Will default to the current desktop resolution automatically (VSR/DSR can be used by changing your desktop resolution to the DSR resolution before launching)
Includes patch to hopefully solve shadowing issues on AMD cards (not fully tested as I don't own one, please let me know whether this helps or not!)
This should also remove the EXE filename check that prevented texmod from working, haven't had a chance to test with it yet though but hopeful they'll work together fine.
The AMD fix is similar to the one that was created years ago for P1, but works slightly differently, would love to hear back from any AMD users that try it!
i have a 6700 XT and its working flawlessly, thank you so much, i came across your mod just googling in case someone finally fixed it and your mod showed up. I can finally play prototype 1 just like i remembered and play P2 that my pc always struggled with even when it released. you're a god! Have a very great year !
Hello man first thank you for this mod the game is stable now but i still have some issues with starting a new game (the infinite loading screen ) i saw on steam that you need a certain german audio file to get it to work could you please figure it out if there is any other solution for the infinite loading screen and introduce it to the mod or add a more compressed version of he german file 1.2gb
if you do everything this user says to the letter, it will fix that, as long as you have the fix and steam closed by doing what he says here: https://steamcommunity.com/sharedfiles/filedetails/?id=2235904856
what fixed it for me was downloading prototype2engine.dll file on https://www.dll-files.com/download/a56fb1340f78dca5f91634d003952215/prototype2engine.dll.html?c=em40V1pvUGZqWjF4UUxyVTI1dWJwZz09
Hi Nice work i used your p1 fix too i wanted to ask if you could work your magic and add some additional features
- holding button instead of mashing it, like p2 why ? just why ? - fix the damn camera sliding off to one side or the other - unlock the camera, sometimes when you are close to something the camera just refuse to turn - make walk toggle ( yes i like to walk )
either way it is good to see game still getting love
edit : oh and mute heller during walk i like the game but that dude is grinding my gears " this uniform is hot, boots never fit " like dude you dont even wearing clothes at all
Works great! can play on newest cpu and gpus. No need to go through any hassle dealing with HID-compliant devices or CPU core count. Thank you so much, I can finally play this game.
Hi! i got a strange problem, i've downloaded aizo v2 mod, and then this mod my last playthrough and it worked together well! now i did a newgame plus and everytime i launch the mod with your fix, it crashes after clicking enter when the game is about to boot to main menu... what could it be?
Same here, was researching and heard it could be from a windows or GPU driver update. Tried all the fixes again and nothing worked. Hopefully the mod gets updated soon as it was the only thing that really worked for me in the past.
Not sure if this helps but I gave up on getting this game to run and moved on to L4D2 (which was also crashing on startup) and see if I had any luck there. I got it running after watching a video https://www.youtube.com/watch?v=5dt-hrX5uoo with a bunch of fixes to try, so I decided to try opening Prototype 2 to see if it would boot fully expecting nothing to happen but to my surprise it worked! The only 2 methods that I believe worked are #14 and #15.
1. Search in the windows bar for "View Advanced System Settings" and click on it.
2. A pop up window will appear that says "System Properties" (should be opened to the advanced tab), Click on Settings under "Performance"
3. Another pop up window will appear saying "Performance Options", click on the "Advanced" tab and click on "Change" under "Virtual Memory"
4. In "Virtual Memory" click on "Custom Size" and type these numbers. (Also make sure you select the hard drive your game is installed on)
Initial size (MB): "24576" (without quotes) Maximum size (MB): "49152" ((If you have 16GB of RAM) this was mentioned in the video relating to L4D2 so I am unaware if this matters for Prototype 2)
5. Then press OK and restart your PC
Thats it, hopefully this works and helps you get it running after nothing else worked.
Also keep in mind you still may need the Prototype2Fix installed for this to work even though it may not work on its own, I did.
Thank you for the mod its working but i have a problem. I've been playing the game for 3 days and i complete 31% of game. When I opened the game today, I encountered the error 'Failed to save data.' I tried the solutions on the internet but they didn't work. How can I fix this problem?

Method 14: Install Visual C++
https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist?view=msvc-170
I had already did this before but I figured it couldn't hurt doing a repair on both (X64 and X86).
https://aka.ms/vs/17/release/vc_redist.x64.exe
https://aka.ms/vs/17/release/vc_redist.x86.exe
Method 15: Change Virtual Memory Settings
1. Search in the windows bar for "View Advanced System Settings" and click on it.
2. A pop up window will appear that says "System Properties" (should be opened to the advanced tab), Click on Settings under "Performance"
3. Another pop up window will appear saying "Performance Options", click on the "Advanced" tab and click on "Change" under "Virtual Memory"

I've tried:
* Switching the sound mode to TV
* Disabling all other sound devices.
* Setting my sound device to 44.1/16, 48/16, and 48/24
