Yup, I barked up that tree a little while ago...
Bottom line is, Locomalito makes his games in Game Maker. Yoyogames, the developers of Game Maker have next to no interest in supporting or releasing modules for the GCW.
But, GM supports linux...
I've contacted Locamalito and he said this:
It's not possible to port my current games to other platforms, as they are made with Windows Game Maker. The only chance is for a crazy coder to rewrite them entirely from scratch and for free, so imagine...
With that and all, there is actually one of my games rewrited for linux, pandora and caanoo, L'Abbayes des Morts, so maybe the door is not closed at all :-)
And, there is an effort being put forward to have Hydorah re-written as well:
