>>328787275) the emulator sucks. Slow, buggy and inaccurate.
Some like to suck its d**k and say, "but that's because it's accurate! That's the price to pay for excellence you bastard" but many of these just want to promote it over no$gba and drastic (which they hate for being paid, or proprietary, etc)
In fact EMULATING THE EMULATOR THAT'S ON ANDROID is FASTER than desmume. (Apparently their solution is to mow more lawns to get alienware for desmume specifically, more demanding than fucking dolphin). Recent versions 0.9.11 of desmume had people try to add a faster recompiler and they too got sabotaged until their fork was more popular than the official and then he included it.
He did something similar with the high resolution fork some Japanese guy did (and even added some fixes for faster emulation!), and waited two years until no one was using the official one anymore and EVEN NINTENDO added upscaling to the bare bones DS Virtual Console on WiiU.
It's full with bugs related to timing, 3D, graphics, for which there's no real incentive to fix even when there's actual contributors willing to put in the work. And when they do they're treated abrasively all the way through only for him to take credit for the late addition. He's a piece of work.
More and more contributors realize the code base is beyond hope even for forks so many started their own emulators and they already fixed bugs desmume left in for years.
