I can see the ds cv games being ported to a console with the stylus being emulated with an analog stick. For dos, I can see the rt analog be used to make the symbols
But with that said, some games would behard to play despite the touch feature can be emulated through different methods. With a ds emulator for the pc, one can play ouendan with a mouse, but because onehas to drag the mouse from one area to the other, I can see it bein difficult, especially if you have to hit the lower left corner and then the upper right.
However, if the game does getported to XBLA, I can see some ppl complain about them not improving the graphics. Moreover, midnightsun is correct in that it is unwise of Konami to port OOE at the same date as the ds version, especially how the XBLA would be cheaper.
