Looks very nice, thanks orz8
If you do make a converter, be sure to remember that (unless this has changed sometime in the last year) you don't need to run the xor-enc against the BMD since clients can all use decrypted BMDs as well as encrypted ones (for backwards-compatibility with some of the older model files). This may have changed since I was last in the MU scene (18 months ago), but it's worth a look.
Better yet, if you can code a bypass for the main.exe so that it doesn't even go through the dec routine for any of the data files, then you could simply dump an entire client's files to TGA, JPG, BMP, SMD, etc and forget about needing converters for every client after that; any new official release can then get decrypted and added into the repository of nice, easy-to-edit files we have to build our custom clients from... Until WZ changes the enc type, but that'll take them a while probably since they'd have to push the updates to every client or be forced to keep releasing broken encryption
I hope some of that made sense!
P.S: The interface looks great, maybe the selection bit looks a bit out of place though? The plain white box for selection, maybe skin it with a frame like the rest of it, instead of a highlighting colour? It already looks pro but I think that would add to it
