Rinne is the first one to crap on other developers, and now he starts drama because someone "leaked" an open source project?
How is that a leak? You're supposed to release the source code, that's why it's called open source. Maybe next time he should make the emulator from scratch so he can call it his.
Maybe if he didn't mistreat the guys making a dreamcast emulator for PSP (which is 100% open source and available in github with 0% drama and 0% egocentric devs), and rather learned to work with them, he would have gotten lot more done.
Now, ironically, the PSP Dreamcast emulator runs better and more games than the Vita's.
