Casio Fx 991es Emulator Download Full
Kaikun97, I think I have an idea.There is 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.Most wanted: a memory dump of a CLASSWIZ emulator (trial version available from Casio).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.hm. You may not reverse engineer, decompose, disassemble, or create derivative works from the Software.Edited by SopaXorzTaker, 04 November 2016 - 09:03 AM. @SopaXorzTaker So you don't like cracked software? It seems this is the only way to get the emulator. And where is the fx-82ES (non-plus) emulator from?
Is it free or cracked?It seems that my idea of STAT 9 failed. Have you tried EQN hack?It hangs on a blank screen for (01:45 for 570es plus, 00:53 for 570vn plus) and display a lot of 'ERROR' text. Can that be used to hack the calculator?I seems to unable to find fx-82MS emulator, but I will find.I had classwiz emulator installed, and I will post RAM dump soon.
When you mention 'RAM dump', is the way to do it like the part To create a dump using Task Managerin? If so I created Redacted linkDo you need a dump of 570 vn plus?-I think VINACAL and CASIO are very, very different due to some hacks I found in VINACAL.Edited by flyingfisch, 04 November 2016 - 03:35 PM.Redacted links to copyrighted material.
Hi guys,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.I don't think any of you intended to be malicious, so I'm not issuing any bans or warnings, just letting you guys know what's going on.To clarify, pictures of PCBs, 'hackstrings', and discussion about reverse engineering the calculators is still allowed, it's just the copyrighted material that isn't.Thank you for your cooperation, and happy hacking! Are you sure that -ES, -ES Plus and Classwiz calculators use the same instruction set? I have five different sources (bold below) of SimU8.dll and SimU8engine.dll, all from Casio calculator emulator.+ The one from you and are identical.+ I also have a pair of dll from another fx-82es emulator, when you replace both files in your emulator with that one it work normally, but not when you replace one file.+ The one from 570VN PLUS are completely different, but is the same as the one of Classwiz model. That's why the can work on 570VN PLUS.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?Hm, that might mean that all the calculators are using the same chip, but running a different firmware each.
@SopaXorzTaker On my machine the program take 1.9MB, reported by Task manager. Do you actually means the one get from (see my 6:22 post)@flyingfisch I seems to be quite clueless about what is banned. ROM dump of a free software is copyrighted?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?Edited by user202729, 04 November 2016 - 04:01 PM. 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 8°5°3° 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 screenI get similar effects with different values of X°Y°Z° so I will experiment with it. Also choosing different Sum options can also cause different glich effects. Ex cubed instead causes a glitched error screenDoes not work on my fx-991ES PLUS, only locking the calculator on any expression with any characters from the glitched Reg menu.Perhaps that happens because of a different firmware. If I am able to buy a fx-82ES PLUS, I'd try this on it. Some information about other models:1. The EQN hack on fx-500VN PLUS take 1 minutes 26 seconds.2.
The forensic result on a 500VN PLUS and a 570ES PLUS is the same as SopaXorzTaker's 991ES PLUS, that is 9 + 7.33338. 10^-9 = 9.3338.3. Checksum. Why is the 570ES PLUS nearly identical to the 991ES PLUS, but the 570ES PLUS has the number in first line less than 1 and checksum greater than 1? So I doubt that checksum is sum of all bytes mod 0x10000.(It seems that those information are hard to find.)LY710X VerASUM D457 OKGY454X VerESUM 8929 OKGY460X VerFSUM D29B OKby user202729, 21 January 2017 - 03:33 AM. 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.In 570vn+ emulator I found a memory block 0x10000 bytes that contains 'Syntax ERROR' text and many other texts that I believe to be the calculator's ROM.Unfortunately the sum of those 0x10000 bytes is 6C69DD and the sum of 0x8000 words is 73B860, different from 0xD457. But comparing detail & checksum of 570es+ and 991es+ (my post above)EDIT: The sum of 0x8000 words above is big-endian. For little-endian see below.Edited by user202729, 13 November 2016 - 07:05 AM.
@kaikun97 @SopaXorzTaker If possible can you find:1) The instruction pointer.2) What determine what page is currently showing on the screen. I managed to find scroll page (page 1 / page 2) but unable to switch between different pages. (For example I can't get to SETUP from MODE)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. The cleansing of bukhari and muslim from useless hadiths pdf creator. I found by pause hotkey) but that can't help.4) From 2 or 3 above (or by another means), how to enter DIAGNOSTIC mode.In my computer the save file (external memory?) is stored inC:UsersAppDataLocalTemp.tmpOne of long hexadecimal sequences is: 2d35374c65376c7573.The emulator can keep value of variables even if I exit that.Anyone know details of es-plus models? (ram size, rom size, etc)Edited by user202729, 09 November 2016 - 02:24 PM. @kaikun97 @SopaXorzTaker If possible can you find:1) The instruction pointer.2) What determine what page is currently showing on the screen.

(ram size, rom size, etc)Could you upload one of those temporary files for me to look into?According to the datasheet, the chip in fx-991ES (not PLUS) has 96KiB of ROM and 3584 (3.5KiB) bytes of RAM.

Could you please dump it and upload the file? Yes, but I don't know about the memory dump. (If we knew then I could take its checksum)I have reasons to believe the rom part in the memory dump is 0x10000 bytes, as I will describe.1.
Using Cheat Engine's debugging feature the ROM is accessed in form ptr + offset, so I guess the ptr is the starting point of the ROM.2. After 0x10018 bytes are next part (I guess external memory or RAM) start pointer.3. Those 0x10000 bytes are the same in all instances (I guess since I just compared two instances).4.
(not very related) It seems that the next part has 0x8000 bytes start with 0.If I can call diagnostic in emulator I would find which address is accessed thus find where is ROM.Edited by user202729, 09 November 2016 - 02:52 PM. Yes, but I don't know about the memory dump.

Why don't we gather all discussion here?Also I am said to be a bot on that IRC channel.I will PM you (SopaXorzTaker) a link to an (old) memory dump of 570vn+ emulator.
The part I believe to be the ROM start at 0x004A84E4 and is 0x1000 bytes long.This was my fault, I incorrectly specified the link. Update the page and try clicking the link in the first post again.EDIT: if your nickname contains lots of numbers, the server may think that you're a bot. Try again with less of them if that is the case.
