Not $200, worse.
It's a subscription now - you have to go on paying forever

So it's great if the same build is working on all models - thanks !

Ok, thanks you very much.

Are they supposed to still work on the fx-CG10/20 ?
(I don't have it anymore)

Quote from: gbl08ma on July 04, 2017, 11:58:13 AMCan you check if my image viewer still runs fine on real hardware for both JPEG and PNG?

JPEG/PNG images seem to be working perfectly. The scrolling is so fast compared to the fx-CG10/20 !

The file browser though has the same kind of graphic glitches as eigenmath :

Quote from: gbl08ma on July 04, 2017, 11:46:44 AMIt appears that the Graph 90+E uses a different VRAM address than the fx-CG50 (since on the emulator for the latter at least, the add-in doesn't show any problems).

I'd advise you not to trust the Casio emulator. Even in Graph 90+E mode apps are working, although most of them don't on real hardware.

From what I could read on http://www.casiopeia.net/forum/viewtopic.php?f=2&t=1783 , the real fx-CG50 is sharing the same problem as the real Graph 90+E.

Quote from: gbl08ma on July 04, 2017, 11:46:44 AM@critor, how do you prefer I send you builds for testing?

Email to [email protected] would be better - since I might not get the PM notification.


Thank you very much for your very prompt reply.

@gbl08ma  It's now summer, and back to school in some weeks.
May we have some fx-CG50/Graph 90+E compatible update of your eigenmath app ?

I'll gladly test it on real hardware if it can help.

Thanks for reading.

Thanks for your quick reply anyway.

Yes, we know about the VRAM incompatibilities and have started communicating about it and fixing things :

@gbl08ma Do you have the possibility to check the eigenmath app, please ?

I'm using the http://tny.im/dl/casioprizm/eigenmath.g3a download link.


It seems to be working but I'm still running into minor problems on the Graph 90+E, when I use the SHIFT+MENU menu.

The display doesn't get cleaned correctly in several situations :


And in the list-menus, the last selected item gets erased in black instead of white, making it invisible :


Wide fractions aren't drawn correctly :


And display cleaning problems too, when the history scrolls up :


No such problems with the same file sent to my fx-CG20.


Thank you very much for reading.

It would be interesting to see a comparison of the 2010-13 fx-CG10/20 PCB's, the 2014-17 one and the fx-CG50 side by side.

Here you are :

fx-CG20 V04


Graph 90+E

(for the fx-CG50, just remove the exam LED beside the mini-USB port in the bottom right-hand corner, and switch the position of one port Q resistor at the right of the ASIC)

Is the hardware based on 2010-13 Prizms? I hope not, because overclocking those could brick them D:

I don't remember which component you have to check on the PCB to determine this.

If you remember :

I've remade the video by adding a TI-84 Plus SE :


1st : Casio Graph 90+E (french fx-CG50), SH4 @118MHz, 8MiB SDRAM
2nd : TI-Nspire CX, ARM @132MHz, 64MiB SDRAM
3rd : TI-Nspire, ARM @120MHz, 32MiB SDRAM
4th : Casio fx-CG20, SH4 @59Mhz, 2MiB SDRAM
5th : TI-84 Plus SE, z80 @15MHz, 48KiB RAM

Check the Game Boy emulation performances :


The Graph 90+E appears to be a little faster than the TI-Nspire CX, although it doesn't prove the hardware is faster since it's not the same emulator.


Same ROM used on 4 models, although the Casio version of the emulator does colorize monochrome games.
No overclocking - original CPU settings :
1st : Casio Graph 90+E (french fx-CG50), SH4 @118MHz, 8MiB SDRAM
2nd : TI-Nspire CX, ARM @132MHz, 64MiB SDRAM
3rd : TI-Nspire, ARM @120MHz, 32MiB SDRAM
4th : Casio fx-CG20, SH4 @59Mhz, 2MiB SDRAM

Too bad the TI-84 Plus CE is missing on this video, we need TI-Boy CE, it's been 2 years...

My guess is that overclocking is not going to help the TI-Nspire CX at all.
Since the fx-CG10/20 could be significantly overclocked, and the TI-Nspire CX just a little before it started crashing.

As far as I know, the problem was with Pover which performs a bad overclock.
No problem with Ptune2.

The Graph 90+E / fx-CG50 CPU runs at 118 MHz (so twice faster than the fx-CG10/20 CPU running at 59 MHz).

In some heavier memory-consuming situations, the new model is even more than twice faster.
Check the huge difference with the new 3D app :

(original CPU settings - no overclock)

You can already overclock with the new Ptune3 beta.
We've reached 236 MHz without any poblem so far.

FlappyBird Color is now working too, thanks to Nemhardy once again.

Originally, you were only getting a completely white screen.
