Nice collection DeViL303, there are a lot

this is going to take me some time to upload to wiki (the .txt file you made comes in handy to copypaste the "tofu" to the new tables btw), i will do in the next days at some point, gime me time
At this point im done with the structure i think, all i know about it is written in the wiki page, maybe i will edit it a bit more today to clean it up or reorder it but im in a pause
@littlebalup now you are going to take a look at the animations try to see if you can identify some of the 7 "unkown" values left from the structure, take a fast look at wiki page, are marked in red (to boost the interest on purpose, hehhehe, this is what i use to call a "dev bait" as a wiki internal joke)
Good work with the pixel conversion, and good point about the targa format, i dont know targa but i can tell sony uses targa format for the original images inside RCO files (before are converted to GIM... orignally are targa in the firmware compilation enviroment), i know because the orignal name (with .tga file extension) can be seen at the footer of some GIM files
So is probable that the images from imagefont.bin was originally targa, and in the process of creation of imagefont.bin the header was removed, then the channels order of the palette was swapped, etc... as you explained
It comes in handy for any kind of custom rebuilder, to deal with the custom images is better to use .tga this way the conversion to imagefont.bin format is direct (no quality loss because the pixel info will remain intact)
