Just for the sake of explaining things, it probably didn't work since your CFW most likely had the GAME folder kernel set to 3.51. However, the folder GAME150 always uses the 1.50 kernel, which gpSP is developed for (the 1.50 version, of course). So, if you boot into Recovery mode and set the GAME folder kernel to 1.50, homebrew developed for 1.50 could be placed in there.
Thanx Mooney, Its always good to know
