DraStic is a powerful Nintendo DS emulator for Android that lets you enjoy almost all the catalog for this portable console. As usual, the ROMs are not included and it is recommended that you only play with your own backup copies.
The settings options of DraStic allow you to adjust the visual quality of the games and even customize the controls. That's not all, once you've started a game you can click on the menu button to choose between the virtual controls, gamepad or stylus. You can also simulate the closing of the Nintendo DS (which could be useful for some games).
As with other similar emulators, you can save your game just by clicking on the 'save state' button and it'll be ready to restart whenever you are.
DraStic is a powerful Nintendo DS emulator that has a huge compatibility list and it works great with most of the games. A terrific emulator, but, do keep in mind that it is totally in Chinese, as you can see in the images.
