JspEdit

Many a Hamumu game uses the ever-mysterious JSP, or Jamul Sprite, format for the majority of their graphics. For years there have been a multitude of discussions regarding what exactly JSP files are. Now, with the power of JspEdit, anybody can mix, match, and create graphics for games based on the Dr. Lunatic engine. Note that this is not a 3D graphics program.

Latest update: JspEdit 1.0 released on January 4, 2011 (first release)
Latest guide entry: SWC Pause Menu (pause.jsp)

JspEdit boats a wide array of features for editing JSP files, including sprite import and export in BMP, PCX, and TGA formats, sprite adding, removing, and reordering, origin modification, complete compatability with all games that use JSP files, and best of all a fully-featured recoloration and brightness modification tool. The download (Zip, 980 KB) includes the executable, two required files, alleg44.dll and palette.bmp, and a sample JSP file, walls.jsp from Amazin SPISPOPD (extract, run, type walls.jsp, hit Ctrl-L and fiddle around).

This space also hosts some info that might help you when modifying graphics or making your own to use in games that use JSP. Check out the handy sprite guide, a reference for the contents of the graphics files of each game, if you're making a mod and need to look up the animations (you can also contribute info if you like). Also, if you're curious about the JSP format, grab the source archive (Zip, 8.23 KB). Feel free to learn from the code to JspEdit, but do not distribute it.
