The attached archive contains a graphic from a game that I'd like to edit. I can view the texture in Imageheat in 128x128 PS2 1 Swizzle format. But I don't know which programs I can use to edit it. Please let me know.

ImageHeat is based on ReverseBox library. Most operations in ReverseBox can be reversed.
If you know programming, you could use ReverseBox directly to do what you want.
Here are some examples https://github.com/bartlomiejduda/Tools/tree/master/ReverseBox_Demo

I think I might have written and posted an unswizzle script for FM4/O a few years ago on Xentax while I was working on the models.

Unfortunately, I'm not a programmer. And I don't quite understand how to use ReverseBox. I tried using MummGGTool and Console Texture Explorer, but I didn't get any results. Although, maybe I'm doing something wrong. The attached textures contain a font and several text strings.
