Hello! Neither the Windows nor Mac simulator shipped in SDK 0.10.1. At this point, I believe the plan is to ship the full toolkits for all 3 OSes in a usable, more-or-less beta state in 0.10.2.
The only pieces of the SDK that are platform-specific are 3 binaries: the compiler (pdc), the simulator, and another general utility (pdutil) for manipulating the Playdate as a storage device. We are not planning to release the source to these at this time.
We haven't started looking at packaging yet. As it's just 3 binaries, I don't think it will be too hard, but it's good to know you're around if we have questions!
(BTW, I have used elementary, and it's really nice!)
