Hey, recently i had just figured out how to create my own custom skins, I didn't make the character's colors Blue and Cyan like people told me to but i didn't feel like it and also i don't need my CPU's to know what item I'm using anyways, so now that is said we can get on to the real topic. So i had recently created my custom skin, and put it into the file called "skins" (P.S: I'm using MM8BDM V.2") so i ran the program and i found my character and everything was perfect, except for 2 things. Every time my custom character got hurt/shot, there was no sound, it didn't make the mega man pain/hurt sound like i thought it would, it does on other players, but not my custom one, also my player's colors (purple and blue) are way lighter than they are supposed to be, look at this picture of my character, the picture in the top left corner is what the color is supposed to look like, the one in the center is what it looks like right now:

Plus, i don't know if this helps but i use GIMP2 to transparent the backgrounds to my sprites and i use SlumpEd for creating the pk3 files. Whenever i open up SlumpEd, it shows this message: "To view graphics properly, you must set IWAD to get the palette from (it can be changed later from the file menu)" I have no idea what it means or what an IWAD is and if it has anything to do with the brightness and sound effect, i always just ignore it and make the skin. PLEASE HELP ME AND TELL ME IF I'M DOING ANYTHING WRONG!!!!
