Progress is slow, but happening.
Been working on Base Gohan (Buu) sprites even though I haven't finish Ultimate Gohan yet.
I'm still not done all the basic sprites for Base Gohan (Buu). Been lazy and working on other things instead...
I have been updating the AI and making some minor improvements. (More improvements to certain characters than others).
As you wait for more progress/updates here are some LOONG overdue Goku moveset videos.
Goku (Buu) - Moveset
SS Goku (Buu) - Moveset
SS2 Goku (Buu) - Moveset
Expect SS3 moveset in the next few days.
EDIT (May 10, 2015):
SS3 Goku (Buu) - Moveset
