You need to run
Nleash to downgrade your OS to 2.0 (dont downgrade to anything less because 1.x isnt compatible with the touchpad series). Ndless isnt compatible with 2.1 yet.
Then you need to get the NDless 2.0 beta, run that.
This is supposedly a gbc4nspire executable that
will run on the touchpad nspire. It was linked in the link I posted earlier, and only launches the first rom in the list. The developer foolishly lost the source, so dont expect an update anytime soon.
Just a note about this: I havn't tried any of this, I was too busy last term trying to pass calculus 2 to try any of this, but I have a clickpad CAS.
Also, TI just recently announced OS 3.0, and thats landing in April as a software update for all of the nspire line. So you might just want to wait on that.
