So, I have been playing a little with the old project called psxdev (a toolbox to make games to Playstation (PSOne), closed now, but we have a mirror thanks to Nobis-Crew) and this is nice cool! Wow! Hehehe!
And, I spent a little time to make the .bs and .tim plugins work with the Gimp 2 (2.0.2 in fact). You can download them from my website.
Have fun! :D
