Well... If you must know, all my utils posted here are made under QuickBASIC. As a Turning language, you can do pretty mutch anything with it.
But it is very uneficient. My tools, for example, take an idiotic time performing very simple tasks. Besides, there is no viable way to code BASIC stuff on the Saturn. Unless you find that BASIC kit thingie. But i've seen some programs for it and the "BASIC" there looks very, very complicated. It's actually something that looks more like Visual Basic, in the sense it's Object Oriented. The manual in Japanese shouldn't help too.
