I used the original textures as a basis to keep the look as close to the original as possible, plus for character textures I used elements from promo art, FMV's & the 'SoT' skins in 'Prince of Persia' (2008) to add more detail.
It's by no means comprehensive, I didn't have time to repaint every texture by hand, but it's still nice to see a bunch of sharper textures in the game 20+ years later.

v1.01 Update:
Some minor fine-tuning (e.g. more visible goatee for the Prince), plus now the pack contains a copy of Peixoto's Injector for easier setup!

What's in the pack?
The pack contains texture files you can use with Peixoto's Injector.
If you just want the character textures, feel free to scroll through them and delete the ones you don't need/like.
I hope you'll enjoy it. If you do, please Endorse it on NexusMods.com & leave a comment, I'd love to know how you liked it.

How to use:
1. Download my mod & Unzip it to a folder of your choosing.
2. Go to the Peixoto folder in my pack & Open Peixoto.bat
3. Find 'Prince of Persia - WW' in the list on the left & click on it once.
(The Injector has some viewability isues on my end, so if the list disappears, try resizing the window until you see what you need.)
5. Scroll down to 'Texture swapping', make sure the box is ticked, then click on one of the paths it offers (I used VOKSI).
Now it created a folder tree in your Documents folder where you can place my files.
6. Extract/move the content of the VOKSI folder in my pack here (both the Dumps+Replacements folders).
Once that's done, you can close this window.
7. Scroll back up & click >Play!
8. When you first run the game this way it will ask you to locate your PrinceOfPersia.exe
You only need to do it once, so in the popup window find your installation folder & double-click on the .exe
(e.g. if you have a Steam copy: C:\Program Files (x86)\Steam\steamapps\common\Prince of Persia Warrior Within)

Yay, your game should be running now! That's it! You're good to go.
(It might take a few seconds longer for the game to launch while it loads the new textures.)

Quality of Life Tips/Troubleshooting:
- To save yourself the trouble of launching from the Injector, just hit ->Create shortcut!
Now you'll have a desktop icon you can use to launch the game easily.
- Super Sampling in the Injector (you can find it under Settings\Forced resolution) did nothing for me on WW (unlike SOT), so I don't recommend using it. Especially NOT Ceilx4, it caused major performance issues on my end.
- For faster startup, I recommend you Delete or rename video files
Go to <path-to-game>\Video.
Delete or rename LOGORP.BIK, UBIMTL.BIK and UBISOFT.BIK, GO_BOSS.bik, GO_CLAW.bik, GO_GEN.bik, GO_SLASH.bik, GO_TRAP.bik, LOADIN0.BIK, LOADLOP0.BIK and LOADOUT0.BIK.

- Though Peixoto supposedly fixed screen issues, you might want to check out The Unofficial Patch by DawidFreeman, which you can find here:
https://www.nexusmods.com/princeofpersiawarriorwithin/mods/10/
It fixes compatibility, widescreen, resolution & audio issues. It's just one file you need to extract into the game's installation folder.
- If you have a Steam copy of the game and it fails to launch, try copying Steam.dll and/or steam.exe into the game's installation folder.
