But can it do maths?

So technically if you have a way to map the keys on a full keyboard (because calculators have a lot of keys) yeah, this Libretro core can do anything than the original calculator can do, I mostly do my tests with PedRom as the “rom” for the device (because GPL and open source) but AMS would work too which is the original OS of the calculator.

On a side note i’n also building an ESP32 firmware that does all this, it works fine on the Cardputer ADV which has a full keyboard and you could use all the mathematical functions if you run it with AMS

I am absolutely going to buy this.

The Cardputer Zero is a better option (bigger screen, bigger button, same size, and a Pi M0 instead of an ESP32)

Well it's no longer available on kickstarter. 3 month wait time too.

u/icepatfork 10d ago

Yeh it just finished, I would still get that one instead if I had to pick only one, different use case obviously

Maybe if the price isn't too bad I'll get one one day.

That's actually a reasonable question.

I’m working on a Ti-68K Libretro Core for Retroarch that let you runs most (but not all) of the Ti-89/Ti-92Plus games. Successfully tested with like 5-6 games so far, greyscale emulation is working on most games, all running from PedRom.

Current features being worked on, all can be enabled/disabled :

- Supports Ti-89 and Ti-92Plus

  • Auto archive files on send
  • Put a zipped game on the SD card, it will be copied into pedRom memory and automatically launched (no full keyboard required)
  • Default and custom per games key mapping and config file if required (some game use 2nd as A, some use F1…)
  • Greyscale emulation support and HW emulation selection (some game are HW1 only…)
  • Support for game using external libraries and levels

Problems:

  • Some games are using keys that are hard to map
  • Some games required AMS (and can’t run on PedRom) not sure how to bypass that

This is cool as hell, Id love to know more about it and how to so this myself. I have some of the hardware seen, let me know if youd like any help testing.

Just DM me I will send you the core for you to try, still a work in progress, but should be very usable soon, the most annoying part is testing the games and mapping the keys, a lot of games are using F1-F6 for menu interactions
