In all my years , I've seen unreleased betas where the image was everywhere and the physical no where
We all know this has always been a normal part of it all.
I cannot remember EVER , where a released game for Gamecube. (gt cube, the sequel to GT advance)
My guess the GC version was cancelled and releaed later for the wii instead.
Despite being a Japanese release GT Cube is 90% in English and can be enjoyed , cellm Shaded graphics and excellent controls
