1. which is a 2D O DROID devices can emulate many different retro systems One of the more unique systems available for emulation is the Nintendo DS i through DeSmuME which is a predecessor of the current Nintendo 3DS It has a huge variety of games available for it and some have very unique ways of game interaction via sty lus Dpad camera and microphone The question is how well do games with such input options work on the ODROID What games do work on ODROIDs at all What games are hav ing issues Can you play these games with a gamepad controller or do you need a keyboard and mouse I want to look at these things and see how well ODROIDs perform when emulating an NDS system General Overview The first versions of DeSmuME on the ODROID were very slow and were only able to play a few games that were strictly using 2D graphics Even then it depended on the game if it was working in any acceptable speed and 3D games were unplayable Since the JIT compiler for ARM is now working the speed went up and the emulator runs very stable and fast on the ODROID U3 and higher end ODROID models The speed of vid eos is perfect in all movies that I ve seen RPG strategy game which can only be controlled by gamepad The game uses the D pad and action keys and you can t control it with the stylus which makes it perfect to control with a gamepad The XBox360 controller for example feels very natural for this game and
