Well everyone wants it to work better, but some are under the idea that is the authors obligation to them to make it better without the user having to contribute any. A lot of users are under the idea that they are owed something by the author of the software, and that is very much against the free software movement. It's very sad indeed.
I would like some emulators to work better, but I don't complain about it and make conspiracy theories. I also don't have the skills necessary to improve the emulators so I just wait patiently for the emulator to get better.
