After I finished Polish translation of Kirby's Adventure I went ahead to translate the first game in the series - Kirby's Dream Land. And first thing I noticed, that YY-CHR can't entcipher KDL code correctly and there's just jumbled mess of various sprites. I thought I won't need to edit sprites, but then there's Stage 5 cutscene (Mt. DeDeDe) that works differently than the first four I could simply edit them in hex editor.
As the thread title says: Is there a working way to see and edit sprites in this game with a help of any editor?
