Help with unlz-gba?

[FsfdS]

I tried to hack firered sprites with unlz-gba. But when I replace the sprite and clicked on "write on rom" it says the sprite is too big even through I didn't make it any bigger. When I reduce the sprite and wrote on the rom, the sprite waas messed up. How can I fix the problem.

Unfortunately I have the same problem... In reality all you can do is make sure your picture only has the pallettes 16 colors (or less depending on the palette e.g. Nidoran (f) has less then 16 available colors in its palette) and shrink your picture that isn't the transparent color down to the size of the origional picture without the transparent color. By that I mean every picture is 64x64 but the picture excluding the transparent color can be anywhere from that down and the new picture with the transparent color must be 64x64 and without the transparent color the same as the origional picture was.
