Sortie OS 3.20 Graph 90+E avec Python

I swapped resource data 3069 and 3070 order by exporting then deleting and importing the same but in oposite order and saved the dll while it still was in temp folder - I wonder if it will be enough to fool the update... however another problem is the emergency os update key combination does not seem to put my cg50 into update mode - has no affect whatsoever - can someone confirm the old key combo still works please? Also if someone know that the dll i modded above will be rubbish please let me know to spare me the trouble

Yes, the "OS error" key combo is the same.
It's very tricky because of the timings :
  • press and hold the
    restart
    button on the back
  • without releasing it, press and hold the
    F2
    4
    AC
    keys
  • without releasing these 3 keys, release the
    restart
    button
  • now only release the
    F2
    4
    keys together
  • wait a second
  • now finally release the
    AC
    key
  • press and hold the
    9
    key
  • wait a second
  • release the
    9
    key
  • press and hold the
    ×
    key
    You should now get the OS ERROR screen.
  • release the
    ×
    key

Petit test de performances en calcul avec un algo de seuil par ici :
viewtopic.php?f=49&t=20341&p=234770#p234766

La Casio Graph 90+E est à peu près 3,5 fois plus lente que la NumWorks, ce qui n'est pas mal du tout quand on précise que c'est l'un des modèles les plus rapides. :)

3,5 ça reste impressionnant ! Heureusement que pour le cours de maths, l'impact sera minim.

Thanks, critor. Managed to push my update. All went fine besides clear memory pop up but in exam mode program and python are still disabled. One thing I noticed is os version became 03.20.1202 instead of normal update giving 03.20.0202

Thanks for the information.

About the end of the displayed version string :
MM.mm.ABCD (MM being the major, mm being the minor)

A: Zone (0=None, 1=Australia, 2=France, 3=North America, 4=China, 5=Singapour)
B: various math input/output features: 0 (n/a), 1 (slim), 2 (all), 3 (reduced), 7 (none)
C: build option: 0 (standard), 1 (development/special)
D: Hardware (0=SH3/SH7355, 1=SH4/SH7305, 2=SH4+color)

Since A=1, it seems you flashed the firmware image for Australia.
Either you missed a third firmware image in the .dll for France...
Either it's the same firmware for France and non-australian countries, with lots of hardware checks for the exam mode then.
It's this case you'll need to find and patch them.

Got you. Thanks. Judging by resources size there are just firmwares (Australian and not) plus a bootloader of much smaller size. Following the links you posted about patching firmware - do you know what decompilng software i can use instead of IDA FOR SH4 processor please?

Le python est pas mal mais il y a des manques surtout pour la gestion graphisme qui n'existe pas :(
(là la numworks a sa place d'honneur :)

Oui, mieux vaut alors utiliser Khicas qui propose des instructions graphiques pixelisees (point, segment, polygone, arc/cercle).
