If Kuuga 9 isn't working on your PS3, that's because I messed up the settings. I'm currently uploading a new copy now which should be compatible.
Oh, and if you wonder why Kuuga has such a low resolution, it's because the DVDs are terrrrrrible:
It's got the black bars that just waste space. Normally a wide video DVD fills up all that space and gets resized. Toei, Blu-Ray Kuuga please?
