Hi, after a lot of trial and error and searching around, I finally got re6 ps3 to load other skins. This guide particularly was the most useful www.ps3hax.net/showthread.php?t=68080 in which I followed the instructions closely. The only file I edited was uPlTex0100_0 - Helena Tall Oaks. I used existing pc .tex ---> .dds files to edit the .dds files for the ps3.
The following images is the result of me editing the body,shirt,vest tex files using the nude mod tex files(pc version)
Sure, its not a clean, legit skin, but the fact that it works on the ps3 has gotten me looking forward to getting a successful skin. Also, I'm a complete newbie, so could anyone explain to me what the MRL files for and any tools to modify and edit (if its something important). I can't find info on it anywhere.
