Fixing tilesets is quite easy, really. I do it by taking screenshots of the unxifed version in JCS, paisting them together and cropping out the non-tileset part. Then I erase all the sky tiles and add a mask. I may make this sound a bit too easy, but it aint hard



You can take screenshots by pressing Print Scrn and then in any graphics program, go to edit and select paiste. Or, if you have a good GFX program, use its screenshot feature instead.
