This is a fork of Graph 89 to support 64-bit OS architectures and the modern Android Storage Access Framework.

This app is not actively being improved.
Special thanks to eanema for their work getting it working with 64-bit devices.

Ratings and reviews

Love the app on my Pixel 8, but I can't access the settings once I've loaded the rom. On older phones I'd press the back arrow and it would bring up the menu, pressing it twice would close the app. Now hitting back once closes the app and no menu pops up. If this gets fixed this will once again be amazing. edit: found the emu button which brings up the menu. Incredible!

Best TI89 emulator out there.

finally in 64bits. thank you!!
