Hello, so I did some searching and found two threads about .JTEX image files, and in both of them, a kind person named Ploaj provided tools to view and convert the images.
I've used those tools on a couple other games, and had an issue with some files. I'll show an example from Pokémon Picross.
Some images look just fine, like this sprite sheet:
![[Image: Upper_Info_Common.png]](/image.php?src=http%3A%2F%2Fnoproblo.dayjo.org%2FJTEX%2FUpper_Info_Common.png&hash=fd23b6caa634c06e9444b8fe0b41d821)
While others are garbled, like this background image:
![[Image: TitleL_Bg.png]](/image.php?src=http%3A%2F%2Fnoproblo.dayjo.org%2FJTEX%2FTitleL_Bg.png&hash=1bb2557200ad67cb8739ccb3016810f0)
And when garbled images have transparency, the colours get messed up, like the edges of this font:
![[Image: ShopFont.png]](/image.php?src=http%3A%2F%2Fnoproblo.dayjo.org%2FJTEX%2FShopFont.png&hash=5325aad7731d39348632669a9bc96089)
I've looked through a whole bunch of them, and it seems like the images that get messed up are the ones with a height and/or width not equal to a power of 2.
Unfortunately, I'm way too newb to understand the JTEX file format, let alone write any tools for converting them. But if someone with more knowledge could take a look at the issue, I'd appreciate that! Will post some sample files if needed.
