However, note that TI is now requiring you to fill out a form\nconfirming that you aren't using it for an emulator—even though that's\nexactly what you're doing with it.\n\nNow, take the `.89u` file and rename it so that it ends with `.89u.tns`.\nNow, send that to the calculator, along with the [latest version of\nn-89]. Finally, select that image when starting n-89.\n\nAlternatively, you may create a `.img` file with [TiEmu] and load it\nwith n-89, if you have a ROM dump from a physical TI-89.\n\n\n[TI-Planet]: https://tiplanet.org/forum/archives_voir.php?id=1863\n[TI directly]: https://education.ti.com/en/software/details/en/6633925F6176419197BF6CA051F5F7B4/89ti89tioperatingsystem\n[download TiLP]: http://lpg.ticalc.org/prj_tilp/index.html\n[downloading TiEmu]: http://lpg.ticalc.org/prj_tiemu/\n[latest version of n-89]: https://github.com/lights0123/n-89/releases\n[TiEmu]: http://lpg.ticalc.org/prj_tiemu/\n\n# Usage Instructions\nAfter selecting the location of your `.89u` file, you will enter the\nemulator. Press the ?:▶ button on your calculator to access the key\npicker, allowing you to press any key available on the TI-89. Press the\nmenu key to access the quick function menu, where you can press F1-F8.\nPress both On and Esc at the same time to exit.\n\n# Roadmap\n**Note that I currently have no plans to work on any of these (except\nsaving state), and this emulator is already good enough for my needs**.\nHowever, I would be happy to work on additional features if people are\ninterested. **Please let me know if you would like to see any of these\nfeatures**.\n\n- [x] Direct ROM conversion without TiEmu: there are many issues with\n      DLLs on Windows and several issues with building TiEmu on Linux.\n      Either having a website with WebAssembly that runs the emulator or\n      built into the calculator app would be useful.\n- [ ] Saving state support: support for saving the RAM between launches.\n      This would greatly speed up startup, and would allow installing\n      additional apps and saving variables.\n- [ ] Other m68k calculators: This may already be compatible with other\n      Motorola 68000-based calculators. However, they are not tested.\n- [ ] Other calculators: a TI-84 CE emulator would not be hard to get\n      working by porting CEmu.\n- [ ] Faster emulator: if anyone would like to improve the TiEmu code or\n      (preferably) port it to Rust, that would be extremely helpful.\n      There have been no changes to TiEmu since 2007, and it likely can\n      be optimized from there.

Your .tns file will\nbe available as `n-89.tns`.\n\nYou can toggle debug mode by changing `DEBUG = FALSE` at the top of the\nMakefile.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Flights0123%2Fn-89","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Flights0123%2Fn-89","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Flights0123%2Fn-89/lists"}
