That's the uploader/editor for Saturn Basic games. The file we see are not the result sent to the saturn. They are provably turned into some kind of bytecode(like a assembly for a pseudo BASIC processor the CD that is placed on the Saturn emulates). It allows for all kind of stuff, like just uploading the changes between edits, saving upload time.
I just found out about this thing, so don't ask for mutch help. I don't have any idea where to get it. And if you think it's hard to code with the SGL and tons of english documentation, wait until you try a non-standart BASIC with japanese documentation and sample code that is well, BASIC, ie. one file, imposssible to follow, all with japanese coments. That should be a trill.
