TI-85 reloaded: the DS85 Release 2

Before there were DS and PSP homebrew games and their respective homebrewers, there were other handhelds that people turned into homebrew for their uses. One of these was a Texas Instruments calculator known as the TI-85.

It was a graphing calculator that allowed you to input numbers to represent graphs in various configurations. At the same time, anyone who spent a few hours poring over the manual could try and program a game for himself that would automatically be stored in the calculator’s memory. Perhaps in fond memory of the days when he held a TI-85, Davr has programmed an emulator of the graphing calculator on the Nintendo DS, which he calls the DS85.

According to him, it will work pretty much in the same way the TI-85 used to, though you’ll have to use the touch screen for typing down numbers and letters. For those who want to forego those sorts of calculator-y aspects of the emulator, the file also holds 12 games made for the TI85 emulator itself, which you can access through the DS85’s interface.

If you’d like to know more about how to use it, don’t hesitate to email Davr and check the included readme. You can also watch a video of the DS85 in action here and check on the changelog below. Enjoy!

New Features:

• Saving & Loading State
• Support for loading Virtual TI save states
• ROM & Save/Load support for non-libfat devices (GBA Flashcarts, EZ4, G6)
• Can turn frameskipping on & off (when skipping is on, speeds things up a bit)
• Can toggle between real speed and full speed. (full speed is actually faster than a real TI, but it makes it hard to play games)
• Comes with an included save-state with several games already loaded. (Usgard shell, ZKart3D, ztetris, solytare, jezzball, Lunoid8, mineswp, and PhoenixZ)
• Toggle between proportional and stretched scaling modes
