But there are some games on the DS that barely use the control buttons or the bottom screen. Some games you can tilt your DS to play sideways. Those are the type of games that can be emulated on the iPhone. For example. New Super Mario Bros. Doesn't use the bottom touch screen that much except for using items, but the control buttons are used throughout the game. So instead of having the touch screen on the bottom half of your iPhone, you can have the control buttons, like on the GBA emulator. Maybe a separate button to use the items. After all, the games will be separate and will not apply for all of them. See what I'm saying? I made another thread about the game "Rhythm Heaven" and how it can easily be emulated on the iPhone since it does not use buttons (except for the start button for pausing, but that can be arranged). There is also one minigame called "Rockers 2" which uses the "R" button, but as I said, that can be arranged. The graphics on the game can be emulated since it does not use that much 3-D effects (except for the minigame "Rhythm Rally" or the "Ping-Pong" game). Even if there was some 3-D effects, the iPhone can also handle such graphics. I could have said Elite Beat Agents but there is already an EBA type game in Cydia called "Osu!". There are many other games that I could say but those are just a few that just come to mind. So overall, I'm just saying that instead of a DS emulator, we could just have certain games ported over to the iPhone seperately.
