As you wish, you may stay with low-level command-line program anyway and then create separate program only with gui, which, after choosing some options, runs programs in cmd adding appropriate arguments (I think this is how psx4m is made - there are command line emulators and gui just runs them with parameters), maybe in this particular case it will be better than messing low level parts of code with gui (and then there would be less possibilities of conflicts if more than one person works on source code). But the decision is, like David Kitt said in his song, up to you
Good to know you're not butthurt about that little immature joke Anyway, I'm glad you solved that issue, that is a lesson not only for you, but for other devs, too And you gave a great reason to fix that ugly bug in autobuilder as soon as possible
