Well i was thinking about how about if is possible t edit paletts of like grass or tress or something. Well i've tryed to open NDS rom with program called Snes Pal (Madfenix) and it works so there must be some offsets that leads you to paletts of tress like.
Sorry for my english

Your English is fine Shirin. So, you said you can open Pokemon in Snes Pal. That is very strange that it would load in a program like that. Expirement with it and tell us if you find anything. Oh and welcome to the forums! Hope you stay for a while, and post often!

Actually it is possible to change palettes, i saw a video on youtube , and it is possible, but the poster of the video, said not to ask him how to do it....

You can edit it with snes pal. Just find the rgb valuse in paint. Then search for the rgb values u found in paint and u'll get tons of offsets. Someone tell me once they find the grass pal offset.
