I know this thread is old, lol, but I wanted to know if their was a way for nDoom to run on a TI-Nspire™ CX instead of just a TI-Nspire™? I have tried to get nDoom running and every time when I open nDoom the calculator freezes and bugs out completely I either have to unplug the battery or wait for the calculator to use all of its power.
