Where do I go to find instructions for creating HD Texture Packs?

I also don't remember if all the textures.ini options are mentioned there, so basically we have:
hash = OPTION
where "OPTION" must be one of the:
The difference between those will be strenght of the hash and performance, quick is the fastest, but can fail misreably in some games, in fact changing it to one of the other can fix some texture issues in some games even without actually replacing textures. On PC at least I think even the slowest one would be fast enough, but mobile as well as ancient low end laptops users experience might vary;p.

There are also other options which all can be set to "true" to activate or "false" to deactivate:
video - will allow dumping textures from the video, will not work for all videos through
ignoreAddress - does what it says, ignores address saving textures only based on clut hash and texture hash since addresses are in some games changing rapidly generating thousands of textures, it also requires safer hash option so basically any except "quick"
reduceHash - hashes only half of the texture, this is dangerous for many games, however there's an unfortunate, but somewhat common situation where textures include other/random data within them and can't be replaced by full hash, in some cases this can make texture replacement usable, but again, it should never be casually used, just as the previous option it also requires safer hash,

Those special options are more workarounds to potential problems than anything else through as the main tools of texture replacement are hashes which you can read about in here including syntax explained with examples. There's also hashranges which can be very powerful tool in some cases, unfortunately most of the time can't be used.

Worth mentioning that instead of just dumping all the textures you can use GE debugger(Windows only I guess;p) to export texture you're viewing, doing so will not give you a hash/filename reducing the usefulness for replacement, however for adventurous people, my personal builds have an additional option in GE debugger to also generate that filename/hash. The reason it doesn't exist outside of my branch is pretty much my lazy and hackish implementation, it's also not that essential since dumping all textures is enough for most people.

Textures.ini file which you probably saw in other texture packs and can even create a base one from ppsspp ui, is technically optional, however not only it does enable all the above tools, it also allows organizing textures into folders nicely making it really a must have for any bigger texture replacement project.

You mentioned warped textures after replacing them, most likely you didn't kept the right dimensions and exact positions on your replacement matching original texture. When creating new textures from 0, it's nice to use a modern graphic editing software with layers and start by resizing original texture, preferably by some integer multiplier then use it as background and draw new things on top of it making sure you allign everything properly. If the texture makes it hard to see where parts of it end up as it really does not have to resemble a picture you end up seeing in-game, you might also place some colorful shapes or numbers on it and use that in game to find out where those parts are mapped over a model.
Quite commonly PSP games have remasters or separate releases on different, more powerful platforms, but even if you can use the textures from one platform to another, it sometimes might be mapped completely differently and require heavy edits. IE in PC version a texture of some armor might be very wasteful and simply be drawn as seen on a model with plenty of space wasted, but the same texture on psp might for example only have 1 leg and 1 arm part reusing those for both legs/arms and have all the other parts stuffed tightly around due to very limited memory PSP has. Sometimes it's extremely hard to even recognize the texture you want to replace without looking at it in GE debugger because of how stuffed they are.

Last thing, each game works differently and there's no guarantee texture replacement will be easy or even possible with every game. There will be exceptions, but 2D games tend to be more problematic and emulated ports of older generation games are commonly impossible.

Thank you! Considering that Corpse Party is 100% 2D though, it might end up impossible at the end of the day unfortunately..
