Chrono Cross on the DS? The game has a resolution of 800x600, the DS sadly only has like 267x???, the amount of RAM and the power of the CPU also couldnt support it seeing that the DS only has a 4MB RAM and a 33MHz cpu, there is no TECHNICAL way for the DS to possibly handle the amount of polygons or any other specs for that matter,
but remember,
Just because its not TECHNICALLY possible, doesnt mean it wont happen.
