Texas Instruments has struck back against Nspire gamers and hackers with even stronger anti-downgrade protection in OS 3.0.2, after the TI calculator hacking community broke the anti-downgrade protection found in OS 2.1 last summer and the new one in OS 3.0.1 a month ago. In addition to that, in OS 3.0.1 the hacker community found Lua programming support and created games and software using it. Immediately, TI retaliated by adding an encryption check to make sure those third-party generated programs won’t run on OS 3.0.2.
Even MAKE was sent a legal nasty-gram for just LINKING to something TI didn’t like.
