I've been working on a TI-84 emulator of my own for a few months now. Normally I can detect a bug on my end of the code (engine or UI). But this one is eluding me and I'm starting to suspect it's a TI bug, not mine.
I'm running a TI-84SE rom. I need your help confirming if this is the (wrong) result you get in your calculator. Unfortunately I can't do this anymore. One of the reasons I've been putting this project on hold. The original from where I extracted this rom was stolen from me 6 months ago while staying in a hotel.
