i want to play Wolfenstein on my TI-Nspire CX 2-T CAS but when i copy it on my calculator, there is the message: This document format is not supported. What id I have to do to play it?

Hello.

You need to install/activate Ndless :
ndl3ss.php
Unfortunately, this is only possible if your TI-Nspire CX II is running an operating system version 5.3 or older.

I have version 5.4

Then I am sorry, but you can't play Wolfenstein 3D on this calculator.
There is no way to reinstall an older operating system version.

thanks for the quick help

You're welcome.
