Yeah, I know that nobody's going to bother to make it and that you haven't bothered to search at all.
Dude, did you even bother to read my second argument in my post above you? Obviously you have no coding expierence or common sense. Forget about the controls and screen and everything like that, there are mechanical specifics and CPU power and all that stuff that needs to be emulated. So when you think of a new system to be emulated, think about if an iPod touch or iPhone can handle the processing power that the system needs.
yo Would it be possible to make a rollercoaster tycoon game for the ipod touch sorta like opennttd except roller coaster tycoon??
Maybe, but that's something that would be dealt with in the "games" section and not the 'emulators' section!
