I’ve been getting quite interested in hacking the fx-82AU PLUS II through finding the various results of using the r symbol in computation mode and statistics submode 0.
One thing in particular I’ve been looking for is ways to glitch into CMPLX (Complex) and MAT (Matrix) modes, especially the CMPLX one. Does anyone know how to do this?

Can you give me more info on what exactly you are asking

The Casio fx-82AU PLUS II has various glitched modes and such that allow you to put hackstrings into the calculator, causing freezes and crashes and even getting in other modes. Eg. Pressing equals with the hackstring (7979(7979(7979(7979r in Computation mode freezes, and pressing on takes you to VCT (Vector) mode. What I want to know is if there is a hacksting in Computation mode or Stat submode 0 that allows you to glitch into CMPLX and MAT mode on the calculator.

Ok I can do some research on this if you would like

That's probably impossible. The functions of mode CMPLX and MAT(such as CMPLX-version add/mul/div/sub/sqrt) are removed. I had tested these modes on 82ES+A and they are both corrupted. Anyway, getting into these modes should be possible.

Even if it is corrupted, I still want to find out how to get to them.

OK, then the best way is to dump its ROM(only need to know the locations of some key gadgets), and use basic overflow to enter arbitrary mode. You can contact user202729. Theoretically, it doesn't need any applications of r to get basic overflow. However, that's really hard. So my suggestion is that you can try to figure out the way of getting into Mode 68 or basic overflow using r.

What is arbitrary mode and what does dumping the ROM do? Also how do I do both? I know of a way to get a basic overflow with r in STAT submode 0 so how would I use this to enter arbitrary mode?

The mode is determined by [d_0x80F9](Maybe wrong) in RAM. The value of this 8-bit unit can be varied from 0 to 255, which means there can be 256 modes in total(though most values are not handled at all, which might be Mode68 or something else). You need to create an ROP to edit that value and avoid the calculator being reset after pressing on. You can try to download the repository fxesplus created by user202729 and try to use the 570es+ emulator and see how it works. You need much related knowledge to understand the whole thing if you want to write an ROP by yourself. However, if your target is only to get into those modes, you can contact to someone to help you(maybe only user202729). Dumping the ROM may take many days if you are new to this.

I think it is obvious I don't know much about this stuff... xD

how do you access to complex mode on a fx82 au plus II, how to type r into the cal. according to your "hackstrick"?
