Extract Prizm OS 1.03+ from the updater
« on: September 20, 2012, 02:29:25 pm »
So to extract the OS from the installer provided on Casio's website, you'll need prizmosdecomp, but it only works with OS 1.02 and lower. Today, I found the way for OS 1.03 and later.

So you'll need the .exe on Casio's website, it's a simple InstallShield wizard. From here, the manipulations are similar to OS 1.02, run the executable until you have the connect your calc screen and you'll find files in C:\Documents and Settings\<your login>\Application Data\CASIO\fx-CG10 OS Update\{EF1BD945-AF60-43FD-A487-0D430D3D7911}. But this time, you'll find fx-CG Series OS Update.msi and 1036.MST. The .msi one is the file responsible for the connect your calc screen, so it must contain the OS.

You'll want to extract it with a MSI extractor instead of running it, in my case I used Universal Extractor. Run it on the .msi you got and you should get those files. (In my case, I ran it in a Windows XP VM, then shared a folder with the Mac OS X host, hence the UNIX commands.)

Okay, now we're wondering which one the OS is, or if it's even in a DLL, the filenames aren't helping. Let's find out.

ISSetupFile.SetupFile3 is detected as having the same file format as a g3a add-in, so it must be our OS.

There we go, we have our OS binary, so have fun ^_^

Well, you are wrong. This is the Geometry add-in version 1.01
It seems as if it is automatically updated when updating the OS; however, the OS is still encrypted inside the OSupdateDLL file... but no more: I asked Goplat to add support for newer DLL files, asked him to give me the source code, but he didn't respond. And that's why I called my friend the disassembler and we did it! ;D

So here we go...


+++ Overview of encrypted Casio setups and compatible extraction tools +++

Explanation: The legacy setups contained the two resources UpdateExe.bin and UpdateCode.bin

- UpdateExe.bin is the on-calc OS updater taking over control during the update process
- UpdateCode.bin is the calculator OS image without user flash storage area

UpdateExe.bin is only a few kilobytes large, whereas UpdateCode.bin is about 12 megabytes for Prizm OSes and 2.5 megabytes for fx-9860G/GII OSes.

To use these tools, copy the "OSupdateDLL.dll" file obtained from your %temp% directory while the Casio setup was running, to the same directory as the executable file.

Yeah, as mentionned on Cemetech, we came to the conclusion that file might not be that one, so it must be in the bigger DLL file.

Don't take it personnaly.

I don't get any reply either for Nspire-Ndless related stuff.

Goplat must be very busy.

Could it be possible that Goplat moved on from calculator-related stuff to new life stuff? The vast majority of calculator programmers, even some of the best ones, won't frequent calc forums nor do anything calculator-related for more than two or three years.

Why are there several (2-3) UpdateCode.bin files in the fx-9860G/fx-9860Gii 2.01 update files?
Which one is being used for the update?

Hmm that is strange, could this be due to how there is multiple FX-9860G models? For example, there is the FX-9860G SD (the one with SD card support), the FX-9860G AU (Australian version of the 9860G with half the user archive), the FX-9860G Slim and the regular models. The Slim model is no longer maintained since years ago so OS 2.x is not available for it, but the other models have 2.01 updates.

Quote from: Edu Casio download service
OS Update for fx-9860GII(SD) Ver.2.01
OS Update for GRAPH75(95) Ver.2.01
OS Update for fx-9860G AU PLUS Ver.2.01
OS Update for fx-9860G(SD) Ver.2.01
OS Update for GRAPH85(SD) Ver.2.01
OS Update for fx-9860G AU Ver.2.01
OS Update for fx-9860G Slim Ver.1.**

Btw I know the Graph 85 in France is the original FX-9860G, but which of the 75 and 95 are the FX-9860G SD and the FX-9860GII?

In the fx-9860G 2.01 update, there are 2 UpdateCode.bin files:
  • resource 3040 (OS datestamp is 2010.1227.0915) for fx-9860G, fx-9860G SD, Graph 85, Graph 85 SD
  • resource 3041 (OS datestamp is 2010.1015.1156) for fx-9860G AU
The difference being that fx-9860G AU OSes limit the archive (storage) space to 800KB instead of 1.5MB.


But in the fx-9860G II 2.01 update, there are 3 UpdateCode.bin files:
  • resource 3071 (OS datestamp is 2010.1115.1723)
  • resource 3073 (OS datestamp is 2010.1227.0935)
  • resource 3074 (OS datestamp is 2010.1227.0954)
But this time I don't understand what the differences are, as the fx-9860G AU+ no longer has the archive space limit.

Oh I didn't know about that. Could it be due to processor differences in the USB Power Graphic II models, an impending revival of the 9860 Slim or an upcoming new Fx-9860 model?

Actually, there are five images in the GII OS 2.01 setup included, but they are effectively the same. The only difference is at address 0x24FEE0 (being a copy of the boot code data at 0x300) and the checksum at 0x24FFF8. This is probably used to check whether the OS image runs on the correct hardware.

Those five images should correspond to:
fx-9860GII
fx-9860GII SD
fx-9860G AU PLUS

Btw are OS updates still provided for people with the original version of the 9860G AU or are they stuck with OS 1.xx like Slim models?

On edu.casio.com, fx-9860G AU users can download a 2.01 update exe.
The exe file is exactly the same as the one given to Graph 85 and fx-9860G owners.
(but remember the exe file does include several OSes)

I don't understand why the fx-9860G Slim stopped being updated.

According to Casio, the fx-9860G Slim is very popular in Asia (like the Casio dictionaries) and some OS 2.00 features are banned there.

Slim OS 2.00 is available here: https://edu.casio.com/data/fx0909/9860slim_osup_200.zip
Casio said they did not make a Slim OS 2.01 setup.
