Tkanks for replies :) I figured it out, in Polish we say that if something is made by Russian, it work. My grandma have more than 30 years old mixer and it works now as good as it was working in the past. On Russia site I found program named lz77restructor, program is in English and it work like unlz but only to find sprites, and sprites are in greyscale color, but I find all hidden sprites with offset like 1700000 or something like that, which unlz doesn't find, in nose 2.1 I can edit it without problem :) for editing back sprites I used tutorial found at pokecommunity, it is the same as in original emerald, and now everything work well, I replaced all heroine overlays with edited cropped etc by me overlays of dawn from Pokemon pearl / diamond, now I am making overlays of Lucas and I have two questions, does map use the same palettes which use overlays? I mean if I edit one palette in nse 1.7 which weren't used by any person, Pokemon, everything I found in nse 1.7 does that affect on map? For example grass from green will be blue and yellow or something, next if I wrote credits in a thread on forum for people's who made for example rom flora sky and which person riped these sprites from Pokemon pearl and diamond, can I upload my rom? Or only ips file, I know that I can't upload full rom, because it is against rules
