Well, the only reason we had for not sharing it was that he wouldn't send new betas if we did. But he just said he wouldn't send any beta anyways. I made a donation for N64 support more than one year ago, and it is not even planned for the next version in 6 months. New version which will be based on Qt5, not officially supported on N9 !

And worst of all, I make a suggestion which sounds reasonable to me, and he doesn't even bother answering me directly.... Emumaster was supposed to be an open-source project. He could just copy the current source code on Github and someone else could package it as a development version. This would require very minimal work from him, and satisfy everybody, but he prefers to keep everyone waiting for no reason.

I consider that he didn't respect his share of the moral contract we had, I don't see any reason to respect mine. I don't like to be rude, but I'm really disappointed as he gave a lot of expectation with this project.

Beta testers gave you valuable feedback to improve your software and you should be happy about it. It may not happen in the same way in the future...
