Drastic

DraStic is a fast Nintendo DS emulator for Android. In addition to being able to play Nintendo DS games full speed on many Android devices it has the following features:

• Enhance the game's 3D graphics to 2 by 2 times their original resolution (this optional feature works best on high end quad core devices)
• Customize the placement and size of the DS screens, for portrait and landscape modes
• Fully supports add-on controllers, and physical controls in devices like nVidia Shield and Xperia Play
• Save and resume your progress anywhere with save states
• Tweak your gaming experience with a database of thousands of cheat codes
• Synchronize your save games with your online Google Drive space
• Increase emulation speed with fast-forward

If you have any uncertainties about the emulator please check out the demo version first, which will let you evaluate how the emulator works on your device.

Notes: You will need a powerful device if you want play fullspeed and the free version is only for testing if drastic will run. You can't do anything else.
