Tari from Cemetech has begun working on this TI-83+/84+ game emulator https://taricorp.gitlab.io/tihle/
Currently, Phoenix is supported, but it's still in early stages so I bet many more games will work in the future.
Basically, this is a project by Tari from Cemetech, which allows you to play TI-83 Plus and TI-84 Plus games in your browser without requiring a ROM image or a copy of the TI-OS. This is very interesting, as this could allow the release of calculator games outside the TI community (itch.io, Steam?) without requiring the player to first dump a ROM from their calculator or illegally download one online.

I wonder if that could be ported to calculators (specifically the NumWorks calculator, but also Casio). Games like Acelgoyobis don't actually need a full TI calculator keypad, so with some keybindings and enough processing power it should more or less work.
I bet this could definitively be ported to other calculators. While the goal seems to be to run calc games on the computer without a ROM, there are a lot of classics to play that could benefit newer calculator models.
