The ti5x application does aim for 100% authenticity even if not possible in all cases. Yet, it supports many undocumented features from the original calculator like the HIR registers and the /DSZ nn 51/ (decrement no-jump) instructions.
With the current version it is possible to play the famous Treasure-Island and 3D-Tic-Tac-Toe games. And many original programs are running without modification.
