So, I'm making my first mod. It's good in places, but there are a few bugs I need to work out. I tried searching the forum already, but the only thing I found out was that you need to use a preset palette of colors for your sprites.

One of these bugs is the LeMat Revolver's sprite. When it faces one way, it looks mostly fine, but if it faces the other, it turns into a hideous mess of lines. I've already tried playing around with FrameCount, but that didn't work. The other bug I suspect is related. When you face one way and reload, the magazine is differently colored than when you face the other way, mostly noticeable in the Flintlock Revolver (and it'll soon matter for some of the other guns, when I've made suitable magazines).

Please help! I have a feeling that whatever I'm doing wrong is stupidly obvious...

Also, if it matters: I used The Flagship mod's Walden Mk4 as a template for the LeMat.

Aw, man, and you were so close.

Your sprites aren't in palette. That's, uh, that's it, the whole problem, right there.

Copy them out of your file, repaste over Palette.bmp (Base.rte/Palette.bmp) and re-save as your file.

If you want an extremely detailed version of the above instructions and don't mind installing Gimp, I have a tutorial here. There is also this older tutorial grouping but they've mostly deteriorated.
