A few days ago, a jailbreak tool for the TI-83 Premium CE and TI-84 Plus CE calculator series came out, bringing back ASM support for users who are running OS 5.5.2 or higher on their calculator. However, in order to run ASM/C programs from the home screen or from a TI-BASIC program, you also need ASMHOOK, by Jacobly.
So here is how to run First Fantasy, 1000 Bornes, Wal-Rush, GalagACE and other hybrid TI-BASIC programs on newer OSes:
1) Follow the instructions on ArTIfiCE website (https://yvantt.github.io/arTIfiCE/ ) to jailbreak your calculator to enable ASM once again.
2) Download ASMHOOK from https://github.com/jacobly0/asmhook , send it to your calculator then run it from Cesium or ArTIfiCE. This will enable the ability to run ASM from a BASIC program or the home screen once again.
Normally you should be able to run hybrid TI-BASIC programs once again!
