Hey Mr. Gibbon, not really sure where to post this but I've been using GDL and I noticed a bug. If I save a .zdl config it doesn't save the external files just the source port, additional arguments and the iWAD i pick. Its weird though because I tested with zdl 3.1.1 or whatever the bigger one, that one saves them fine and GDL can load them fine, so it seems like it might be a problem with the actual saving the additional files part. Have you messed around with this lately? I know you're probably busy but if you can take a look at it and see if its doing the same thing for you or if its on my end that'd be swell!
