Beery... I'm having trouble finding the right thing to send you.
For example, with Ghost Recon, on the game disc is included "RSB plug-ins", because the graphics files in GR are in RSB format.
Stick the RSB plugins in Photoshop, and you can open GR files.
I looked for something that looks like RAW plugins in my photoshop, and I don't see anything.
I'm not sure what's letting me open it.
When you try to open the SH3 map, what happens?
Mine looks like this....
