Full description

Emulate any of the following calculators: * TI89, TI89T * TI92, TI92+ * V200 * TI84+, TI84+SE * TI83, TI83+, TI83+SE No ROM images are included. You can extract one from your own calculator or if you have a physical device, download an OS upgrade image from TI. 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. https://github.com/Perihelion-Development/graph89

What's new

Fixed crashing issue in version 1.3.0 on launch for some devices. Fixed issues with sending files to and from the calculator (changed how threading works as part of this) Increased target SDK for Play store policies. Aligned 64-bit libraries to 16KB pages for Play store policies.
