A finally (nearly) complete JJ1 graphic editor.

JJ1MOD will allow anyone who can run Jazz 1 to edit its graphics, not only things like level tiles and sprites, but also the main menu, bonus tiles and even high scores. It also exports level and bonus level images.

There are two areas that are not yet quite finnished, S3M->PSM music conversion and .0SC movie creation. These will hopefully be improved with the final release but remain adequate if not particularly user-friendly in this release.

Problems running JJ1MOD can be overcome in the same way as those facing running Jazz 1, Dosbox is your friend. (JJ1MOD will not run naively on 64 bit systems without it, at least for now.)

Once again I hope to get help with debugging and making this program easier to use. I have followed the tips and suggestions given to me by reviewers of my earlier releases including a drag-and-drop interface and the creation of folders when things like sprites are exported.

EDIT: 2.01: Fixed sprite import bugs, thanks cooba!
EDIT: 2.02: Fixed minor level export/import bug. Thanks again cooba!

To anyone using this in the future: if editing the bmp files this tool extracts in Photoshop, Photoshop will save them with four trailing hex 00s at the end. I have no idea why it does this, but it alters the file size and causes everything to be offset by 1 pixel, causing some nasty streaking. If you want to use this tool and Photoshop, make your edits to the bmp, save it, and then open it in a hex editor like HxD and delete (not clear, but delete) the last four zeros from the file. You can then repack them to BLOCKS.000 or whatever without issue.

Other than that, very useful too, has been fun making some tweaks to the tilesets.
