Review

It is currently the best Nintendo DS emulator out there. It is far better than No$GBA.

Troubleshooting

If the game is slow.

  • Enable the dynamic recompiler in Emulation Settings.
  • If it's still slow, you must be running on a toaster. It can't be helped. But try tinkering with things for the fastest settings you can find.
  • Use frameskip as the absolute last resort.

If the sound is distorted.

  • Synchronous mode is far less buggy. Method Z seems to work the best in most cases.

If the video is hideous.

  • The only real thing you can do is filter it. Make sure OpenGL and Filter are checked under Display Method.
  • Yes, filter it. Whether that is simple Nearest 2x or some smudging filter like HQ4x is up to you.
  • Leaving it native and aligning it to a CRT (Set to a 384 high resolution) is also an option, if you feel like going through the effort.

If the 3D is messed up.

  • Set it to OpenGL 3.2. Old OpenGL had problems with 3D itself, while Softrasterizer had alignment issues with 2D. But 3.2 seems to fix most of both.

Internal resolution

Internal Resolution and NDS Emulators:

tl;dr: Not currently possible via regular means. Use filters (e.g. bilinear) if you can't live with jaggies.
