OK AKA Smitty-werben-jangerman-jenson.
I've been known for doing a lot of head scratching, as we are all in the same boat.
It can be a real pain in the whatever.
Because it is very exacting, a wrong change will make the default white skin turn on.
Looking at the image above, probably the bigest concern is, the size has changed.
I used Pixelformer.
I made the bitmap 1 all same grey. (the base color, with alpha transparecy level)
I made the bitmap 2 all same red gradient. (the red mask, that uses the system glass color)
Found out after doing the same to the search, and jump bitmaps, they all look the same.
I did not need to modify the other bitmaps 8,9,13,14. Just change text to reuse bitmap 1 and 2.
Tell you what, I can only torture a person for so long, before helping out.
I'll put the modded two bitmaps in a zip for you to replace in the skin file.
Here is some of the text changes that I made in the script:
Main_bitmap=1
;Main_bitmap_search=8
;Main_bitmap_jump=13
Main_bitmap_search=1
Main_bitmap_jump=1
Main_bitmap_mask=2
;Main_bitmap_search_mask=9
;Main_bitmap_jump_mask=14
Main_bitmap_search_mask=2
Main_bitmap_jump_mask=2
Main_opacity=fullglass
Main2_opacity=fullglass
;Main_bitmap_slices_X=11,2,3,4,2,24
Main_bitmap_slices_X=12,2,3,4,2,25
Main_bitmap_search_slices_X=11,2,35
Main_bitmap_jump_slices_X=12,2,3,4,2,25
If you can get past the important bitmap changes, you will have confidence to do the rest of it.
If you throw in the towel, and give up, let me know, and I will upload the finished mod skin.
