If the head of Mecha Sonic change, it is because the size of this last should be more big than that of Sonic. Maybe a bit stupid of my part, because i follow for the moment no guides, only tutorials. I will show to you an old screenshot for you understand what i says: Do not focus to the giant ball and the eggmobile graphic, just see the head of the character, with the visible black color, who is not normal (it is a dark gray normally, but it is negative here). I had fixed it, but this start again, this bug disrupt me, and it is since yesterday. I had worked while more of two hours, i return to the same bug... Otherwise, here is the new graphic: Look at that... "very ugly the ship!". No! I says of the head! The ship, even very ugly, with a color substracted, is correct. Now, you understand that i want to say, and it is very disturbing, and even in searching some thousands solutions, i stays here, in the same issue! If you see above of the screenshots, i used Gens, so i am not in luck. If i do not take a guide, it is because i do not know a "real" guide, for make a rom hack in Assembly and with the rest of the tools. Thanks you for read it, and i am sorry for my English. If somebody can also help me in some issues, i could finish the first world more early than planned.
