I tested BootSkin Buddy people.
Sorry to say, it's flawed with several Bugs.
For basic BootSkins it tested okay, but when it came to more advanced Skins, it said that there were errors, when there really wasn't.
The Program goes by basic guidelines of Progress Bar Size, and Length, but there's more to it than that.
For instance, the first Skin I tried was my newest one, "XP Space Warp"

It gave me an error and corrected my Progress Bar's expansion running Width from 144 Pixels in length to 154. Which of course put it out of bounds of my Progress Bar Window. When I tried to correct the Program's mistake, it gave me a message saying that During actual Reboots, Progress Bar Lengths are rounded to the nearest multiple of 22. Which actually isn't true.
Another flaw, the Progress Bar size.
It keeps everything at 22X9 pixels.
Uncle Rob is proof that it'll work at higher resolutions.
All of his Progress bars are 28X10. Granted, his y coordinates 1 and 10 are always the same as his background, so when they get cut off you don't notice,
but his X resolution of 28 pixels works on every boot with no problem. It shows all 28 Pixels.
I haven't done any testing yet, but I believe you could probably create even longer Bars. It probably would effect the right side of your screen where the latter X Coordinates are, possibly creating a static residual image leftover from the Bar, but if placed in the correct spot, you could probably make a long Bar with no side effects. Not sure, only a theory.
I'll have to test the Program out with my "Alien Stonehenge" and "Three Wise Men".
They stretch the limitations of the Progress Bar coordinates in both directions.
In any case, if Xander works out the bugs in the program, it'd be a fantastic work of art to use with the BootSkin community and for Moderator's assistance.
Plus, I LOVE the Full Screen Preview mode!
