Got it now! Click the jigsw, then when its loaded, click the menu called Picture, then Save Tileset 2. Then open the pic in Paint, and insert your tile!
Its a bit more complicated. The jigsaw is a shortcut, its hard to explain... I'll try. There are 2 big pics. The left one, and the right one. Click File. Pick Save Tileset 2, save it, and thats what you can insert into. There are different pallettes, which can be changed. There should be a menu just above the centre pic in Advance Map. That is the pallette changer. Pick the right pallette for the colours you want.
Yeah... That Colloseum cannot be inseted. Its good, but its not th quality that makes it uninsertable. Its the pallettes. The pallettes cannot let me insert it like that, or anything near that. If I could I would, but... Also, the size is hard to make into tiles without deleting tiles we also need... Good though!
Not many, and those people have loads of events. Events are worth a few shinies as well as other Events (a Shiny Event is very hard to get) Also soon Events will be limited.
Depends how good their stats are. It varies on 3 key points. 1, their IV's (research that), 2. where the EVs are put and 3. The natures of the pokemon.
