No sources = no port from the community
If people want RPG Maker on a non-windows system they have to convince the original developers of RPG Maker to make a port for that system.
They have made ports for non-windows systems. Specifically, Nintendo and Sony systems.
But while there's plenty of games made on the Playstation versions to be found on the web, I haven't found any made with the SNES/GB versions...
