Tried to look at this a year ago and yeah there might have been advancements with it in the past year but I think i might stick to making Button Replacement packs for it once someones completed the full Texture pack (if that happens)
Well I have some more good news.
I have been replaying the game and manually checking for corrupted or vram garbage texture files and cataloguing them by level.
Every single vram garbage file shares 2 qualities.
-The first is that they are always 256x256 or 128x128, though sometimes the filesize is double the norm
-The second, and more important one, is that they share the same NAME.
When PCXS2 dumps textures, it gives them a specific file name, usually hyphenated 3 times into 3 sections, such as "3412772e9bce81f1-9b43279d63b013aa-00001dd3"
a 4th section is for designating mipmapping layers
I believe that the second and third sections of these names denote what the texture is being applied to, or where it comes from, because they are 100% consistent for duplicate textures.... and ALL of the vram garbage false textures.
Every garbage texture shows the same sections of "10487f6bdcc97e58-00002213"
every single time.
It has no legitimate form, meaning it serves as a simple way to filter out ALL random garbage textures via a simple search in windows explorer.
and I am ONLY encountering random vram errors. Real textures dump just fine, as far as I can see.
I still need to eliminate the possibility of a few other errors and experiment with replacing textures to make sure nothing else is going weird with the texture dump, but this is looking very promising.
That said, I might need to do some extra runs for the bad ending cutscenes. This game doesn't use pre-rendered cutscenes anywhere at all; its 100% in-engine.
So a modest texture replacement will upgrade the look of almost everything.
