Uncaught error: Texture error: Frame does not fit inside the base texture dimensions
My guess is that you're trying to patch the wrong version of the game. His patch is for the latest version, which I don't believe has been posted in this thread. I can't confirm though, since I don't own the game myself.
Instructions are basically:
1) Download the latest version from DLSite (1.3 - March 02, 2024). This translation will ONLY work with this version.
2) Download Milky0's version, so you have the files from it.
3) Transfer the listed files from Milky0's (Johan's?) version into 1.3
3a) As you said, it should be "www\img\pictures" and "www\img\spines"
4) Download Azertytripleh's translation files, and overwrite all of the relevant files with them.
This would be much less confusing if the initial upload just contained all of the necessary overwrite files in a single zip. No need to make it a scavenger hunt, lol
I went ahead and combined the 2 patches together, and simplified the instructions in the folder. I DID NOT make this patch, the credit for that goes to Azertytripleh and Milky0
EDIT: Didn't work, deleted the file to avoid confusion.
