[Feature Request] RetroAchievements Support

[TheFetishMachine]

RetroAchievements is a website, community and service that uses emulators to add achievement support for a variety of game platforms (not only consoles) by hooking into the emulator's memory. As there is a healthy TI calculator homebrew scene, I think it might be nice to have RetroAchievements support for all the available games.

NB: Yes I am aware this TI-84 emulator called CEmu isn't the same as the Wii U emulator Cemu :P

Here are some documents on how integration works: https://github.com/RetroAchievements/RAInterface/wiki/Creating-a-new-emulator https://github.com/RetroAchievements/rcheevos/wiki
