  • Q. Why doesn't my desmume play this game?
  • A. Go to desmume.org and make sure you are using the latest version. Hint: desmume 0.8 is very old. Older versions will not be supported, under any circumstances.

  • Q. Why does this game fail to save?
  • A. Desmume's autodetection for save types is not very good. For now, you need to manually specify the correct save type for your game. Consult the manual for details on how to do this for your platform. We want to fix this, but there are no specific plans so far.

  • Q. Why can't I find a mac binary?
  • A. There is no official 0.9.1 mac binary. We do not have a very active mac port maintainer. Volunteer yourself. Or wait for 0.9.2 where the windows release manager is going to give it a shot.

  • Q. Why doesnt my 3d openGL work in linux?
  • A. View the threads HERE and HERE and HERE. Alternatively, wait for 0.9.2 which will have a software rasterizer

  • Q. Why doesn't my 3d openGL work in windows?
  • A. You are probably using an ATI video card. ATI driver support of OpenGL is known to be poor. Get an nvidia. Do not argue with that, we are professional programmers and know what we're talking about. Alternatively, wait for de3smume 0.9.2 which will have a software rasterizer instead of having to rely on openGL.

  • Q. Why doesn't a menu option or tool exist in my linux or mac build?
  • A. Because making portable tools and platform harnesses are not our cup of tea and so a developer puts a feature into whichever ports he cares about. This policy is never going to change, although soem features might migrate to other platforms over time.

  • Q. Why does music sound bad sometimes?
  • A. Most DS music is sequenced music, loaded from the cart to the ARM7 entirely when the level loads. This works fine. Your music that doesn't work is probably streaming music, which loads from the cart on the fly and goes straight to the speakers. This is much harder to emulate as it requires correct timing, which is not one of desmume's strengths right now. This may not be fixed for a while.

  • Q. Why doesn't my game boot or progress into the main game engine?
  • A. Desmume is not perfect yet. Some games may fail due to wifi emulation. Apparently if you search the web correctly you can find ways to patch games to work better on emulators.

  • Q. What hardware features are emulated?
  • A.
. All known 2d graphics features
. etc test

  • Q. Why is the emulator slow?
  • A. Because nobody pays us to work on it full time and it runs fast enough for us to be happy. Well, almost. The cheapest way to get 60fps is to buy the cart. Buying a newer, faster computer is somewhat more expensive, and it has other side benefits. Also, if you are in Windows, make sure you have tried the SSE build which helps a little bit. Additionally, if you are using someone else's interim build it might not be fully optimized since we make our Windows releases using some profiler-guided optimization which helps by several FPS

  • Q. Does desmume support wifi ?
  • A. As of version 0.9.1, Wifi is not supported. It is currently under slow and incomplete development.

  • Q. Does desmume support the microphone ?
  • A.
