You could use the famous PxlOff 1,1 trick to force a screen refresh. ;-)
Actually, lots of those refresh issues were fixed with the fx-9860G series; however, a few are still there...

Maybe this is because the program execution stops after RclPict 1?
Try putting it into a loop or append the small triangle command after RclPict to pause the interpreter (until you press [EXE]).

Does special characters actually take more space than the regular ones?

As long as they're non-ASCII.

Does this allow copying individual programs to the RAM? Being forced to copy entire packages might not be something I want, especially when each program is 15 KB large.

As far as I know, this copies any program within a *.g1m/*.g2m file into the user RAM.
You may ask Simon to obtain the source code.

Nope, no luck. Here's my code (Casio Prizm OS 01.01.0200):

Code: [Select]

Cls
Vertical -3
StoPict 1
Cls
BG-None
RclPict 1

And if you go to RUN|MAT and enter "Cls:RclPict 1"? This will display the coordinate system with an additional vertical line on my fx-9750GII.
Inside RUN|MAT you can press [Shift]+[F3] and reset the view window with [F1] - just in case the vertical line is not within the display area...

-One question I have is can we omit quotes at the end of Locate? In TI-BASIC you can do things such as Output(1,1,"HELLO WORLD instead of Output(1,1,"HELLO WORLD") as long as the next code is on a different line, but I was wondering if it was the same on Casio? That usually saved us some bytes of RAM.

"Locate" and "Text" seem to allow this, but it's bad practice and does not seem to work with the ":" command either. Actually, I have never used this. The few bytes you save get lost by using special characters.

-Also are there any assembly tools that allow us to run programs directly from the Storage memory

Maybe this is what you are looking for?

-Also how would we recall a picture from a program on the Prizm? I tried RecallPict 1 (after storing a pic with StorePict 1) and it does nothing...

You could try clearing the screen first using "cls" and you should disable any background image with "BG-None". Unfortunately, there is no way to test if a picture exists - causing a memory error sometimes.

Ah ok, thanks for the clarification. Strange that french models requires such additional step, though.

This is mainly because on an fx-7400GII/fx-9750GII starting the OS update procedure via LINK/Receive has to be hard-coded (due to missing syscall support on these devices) and this beta version of pfxrecover does not know the checksums of French models yet. However, Simon Lothar - who wrote the update utility - is already working on an improved version.

You can work around this problem by starting the OS updater via the calc's BIOS when it boots up. This can be achieved on all GII models by a special key combination. On older models you have to close P104 (which is the OS update contact) on the PCB while pressing the reset button.

One question: Why aren't you using IDA Pro Advanced for this?
Simply open the add-in file and select SH3B as the processor type.

A cracked version is available here (v5.5): no.links2piratedprograms.plz
