Help converting old GTX1 (raster?) images

Post by Habanero »

Hello. I've been playing Lost Kingdoms 2 on the Gamecube, and decided to see if I could open the files within. For starters, what I'm guessing are the card images are in the GTX image format. The guides and help forums online say that this can be converted to DDS. However, I tried TexConv2 to no avail (https://puu.sh/EZd2t/407142459f.png). I also tried TexHaxU, Noesis, and GTX Extractor (this seems to only be for Gfx2), which also failed. I'm guessing this is the older format of the GTX image type. Here's what the hex looks like. Searching for "0x47 0x54 0x58 031" didn't bring anything up in Google either.

Here are the sample images. Thanks for any help!

They are in big-endian DXT1 format.
