What is Pokemon Prism?
Pokemon Prism is a long-awaited romhack of Pokemon Crystal version developed by a very talented programmer in the Pokemon Rom Hacking scene called Koolboyman. It's the direct sequel to an older hack he created called Pokemon Brown (hack of Red with a new region and an expanded Pokedex.
Three months ago A trailer was released, annoucing that after 8 years of development, Prism would be released, and would get a special preview stream of the release version on Twitch Plays Pokemon's twitch channel. Unfortunately, on December 21st, just four days before the hack's Christmas release, Koolboyman man received a cease & desist order from Nintendo and subsequently shut down his site which hosted the patches for his previous rom hacks and canceled Pokemon Prism. A day later however, and anonymous group that had access to the files (it was known that KBM had given earlier copies of the game to beta testers prior to the C&D) leaked the latest possible build of Prism, so the game is now playable if you can find it.
What features does this hack have?

Where can I find this game?
Can't help you there. Typically, rom hack patches are safe to link to on GAF since they don't include the game, but because of the legal issues this game faced i'm going to err on the side of caution and ask everyone not to post links to Prism here or ask for any. Trust your google-fu.
This is what the MD5 and SHA of the .gbc file should of v0.91 build 0144 should look like:
You can check this with a program like WinMD5.
Okay, I have the game, but how do I play it?
Use a GBC emulator. What's recommended for this particular hack is the Gambatte emulator because it's compatible with all the extensive edits made to the Crystal rom. Want to play the game on the go? Check and see if your device of choice can run Retroarch and play the game through Retroarch's Gambatte core. Other suitable methods to play will be posted as time goes on.
How much is playable in the leaked build?
Pretty much the entire planned main story plus most of the postgame. There were some other postgame events that were planned to be added in post-release patches but that will likely never come to pass because of the cancellation. However, Prism does have it's source code available, so there's always the possibility that someone else could pick up the slack down the road!
