Hey there, interested in getting into the filesystem of my calculator. Any ideas? I know it lacks in processing power but would like to play around and see what I can get it to do.
Is there any way to add third party files to a CASIO fx-82AU PLUS II Chacking file modification files

No way to put add-in in that calculator. Even if you found a way, there'd be no support for the device, all add-ins have been created for the fx-9860 or some varient of it.

Actually, I disagree. Although it may as well be impossible, if you were to dump the rom by dissolving the chip in acid and taking a photograph of it or through use of arbitrary code execution via a glitch, you could then reverse-engineer it and then put the rom on an EEPROM chip and just connect a microSD reader or similar to a non-important pin(s) (perhaps a test pin(s)) and the modified rom would read data from that pin(s) and load it onto the calculator.
So yeah, basically impossible, but not completely impossible.
I would like to say however, that the calculator has no file system. It is just raw data such as ASM (but a unique version for the 8-bit microcontroller that the calculator runs from.)
