WARNING: Do NOT upgrade your TI-84 Plus CE to OS 5.5 and higher. It blocks ASM!

I saw this coming years ago as critor would say, but it is now a reality: Texas Instruments has decided to block ASM on the TI-83 Premium CE and TI-84 Plus CE.Looks like from now on ASM will have to be added via hacking or whatever, like on the Nspire. Hopefully it's not as difficult as with Ndless and hopefully there is a way to get the old games to run on the new OS. But this is bad news for TI development, especially considering most games are coming out on the CE.Source: ...
