Fx 570es Plus Emulator

[Shanel Arrendell]

Thereis an fx-82MS emulator (yes, MS, not ES). Could you please dump the RAM of it? I am trying to find if the fx-ES (not PLUS) and fx-MS have the same architecture, and also want to dig a bit into the MS series.

To download it: On tick the box "I have read and consented to the Software License Agreement" under "Free Trial Version", select "fx-570/991EX Emulator" on the bottom of the page where it says "ClassWiz Emulator Subscription v2.00" and click Download.

Unfortunately, we can't allow linking to copyrighted material on this forum. This is because our main source of revenue for keeping the site online is Google ads, and they have a strict policy regarding copyrighted material. I've removed the illegal links from this thread.

Edit: Although we knew that fx-991es and fx-991es plus use different chips, your fx-82es emulator have dll identical to the one in fx-es plus manager trial. Or that may be an error of the fx-es plus manager?

That was accidental collateral damage, I only meant to remove illegal links but didn't have time to check the actual content of each one. You guys can add that link back if you want, and feel free to let me know if there were any other links I accidentally redacted that shouldn't have been.

Is instruction to upgrade calculator (not hacking) banned? For ex., "Open file A by hex editor, search for 123456, replace by 654321 and save". Is that considered invalid if it convert 82es emulator to a 570es one?

Hm found something interesting, remember when I did that glitched barcode graphic earlier in the thread by using the glitched stat mode with the little A and X hat? I tried 853 in the stat data and did Ex sqaured for the sum menu (first option) and then a little A after and pressed equals. I got Math error, then I deleted the A and put an X hat in its place and pressed equals again and I got a glitched screen, pressed the direction keys seem to change whats on the screen

I get similar effects with different values of XYZ so I will experiment with it. Also choosing different Sum options can also cause different glich effects. Ex cubed instead causes a glitched error screen

In fact the one that look most likely to be the ROM in VINACAL II emulator (Sim VINACAL 570ES PLUS II v1.0) is 192 KB, but it looks like that the ROM size is divisible by 32 KB, that is larger than I expected. (so that is better)

So I am looking for where things are stored using Cheat Engine, but only on fx 570vn plus emulator. On the 570vn plus I made a large cheat table. Only a few is done for the 82es one, seatch the web for "fx82es.ct". Only work for some specific model.. SopaXorzTaker you use Linux so probably can't use Cheat Engine or the simulator.

@SopaXorzTaker I am doing that with the 570vn+ emulator (you can find the cheat table in the "Cheat table" section in the link above), and it is very hard to find something. I think what you want is not enough.

3) What determine what button is being pressed. I found the part that determine the highlight on screen (determine by two 4-bytes values that is FFFFFFFF when no highlight. I found by pause hotkey) but that can't help.

We found the leaked u8 assembler, which hopefully can also disassemble the firmware too. We aren't linking to it on the forums, but it can be found by careful googling. At the time of writing this post, it was on the first page of Google search "oki u8 github".

The natural textbook display is a way of displaying formulae in the closest possible way to handwriting. For example, fractions are displayed vertically. This makes it easy to write and edit formulae naturally without the complicated brackets. It is enabled by default on supporting calculators, including fx-82ES and fx-991ES. You can enable MathO mode using SHIFT SETUP, 1.

If you have any questions with any of the content here, feel free to contact me. The content has been created using the Casio fx-ES emulator to replicate the procedures possible on the actual calculators. The interface is identical to a physical calculator of that model.

You can access the Casio fx-ES emulator download used to create these tutorials by contacting me using the comments below. This is the full emulator download with support for the fx-82ES emulator and fx-991ES PLUS emulator. Post a comment and I will get an email to you.

I have a question: on the German market there is a variant available, namely the Casio FX-991DE X. Do you happen to know what are the differences between that one and your emulated version? (I mean, apart from some language terms).

I have a Casio fx-20 scientific calculator dating from the mid 70s. Been well looked after. Today it stopped working (used it earlier in the day). The display is lit (a 0 lights up) -- but the keys cannot be activated. None of them works. I checked the batteries and changing them made no difference. Is there a way to open it up and maybe clean something inside? I love it and want to continue using it. Thank you.

Hello George. Thanks for the quick reply! It works perfectly. I can defenitely use this emulator in class. Apparently, most of the students use a more recent model: the 82 Plus. The design is slightly different but I could not see any difference with repsect to the buttons of both models. However, do you, by chance, also have an emulator for the Casio fx-82 PLUS? Thanks in advance! Markus

Hi, your tutorials are very useful for my daughter and her friends. It help them a lot to start learning how to use this tool. Could you please send me the fx-991es plus emulator? Thank you in advance.

Hi again! Your tutorials are enlightening. I tried to comment here once before but I can't see my comment being posted. I'm searching for the Casio fx-ES emulator. It would be great if you'd send it to me. Thanking you in advance. D.
