No$GBA (Now going to be referred as No$) is the best DS emulator, even though it wasn't supposed to be. As you can probably guess from the name, No$ was meant to be a GBA emulator, but soon became a DS emulator. It's GBA emulation may not be that great, it's DS emulation beats DeSmuME with its speed.
It's graphics for GBA isn't as good as VBA and it's DS emulation's graphics may be too geographical (easier to see the shapes. Is it even the right word?)
It's sound can be bad depending on the rom. It can be slow if the rom is slow/fast. You can't really hear it properly and the songs are hard to follow, but this is only with a few roms. All of the GBA roms should work and most of the DS roms shouldn't have too many problems.
You can easily change the buttons to how you want them and you can easily change the settings to your liking, including the speed of the game.
