Is it possible to transform Prizm add ins in fx9860gII ones

Hi,
Is it possible to transform a "Prizm add" in a "fx9860gII one" ?
If yes how ?
thanks a lot !

If you mean a G3A to G1A binary converter, I'd say no.

What I mean is :
If you have the source code (c. or h. file) from a "Casio Prizm add in" can you transform it into an add in for the fx9860gII ?
If yes how and is it difficult ?
thanks a lot

If the G3A does not strictly depend on special capabilities of the Prizm (color, display resolution), a transformation could be possible.
If not already done, you have to separate hardware-dependent code from the independent parts. F. i. fx9860-NOTEVIEW and fxCG-NOTEVIEW use a common source with appropriate conditional defines here and there. You need two different syscall-libraries with identical interfaces. As the Prizm incorporates much more syscalls compared to the fx-9860s, it could be possible to have to emulate some. Some syscalls have similar but not identical interfaces. They have to be emulated, too.

...is it difficult?

That depends greatly on the G3A source. If hardware-dependent code parts are not well separated, the job will be a particularly tiresome one. But laboriousness shouldn't be an obstacle.

hey,
thank you very much for your fast and precise anwser !
I don't know the C language at all, do you think that
you would be capable to do it ??
I realy appreciate your help !
thanks a lot

At least I can take a look.

I don't ave the codes yet, I would like someone to port the " eigenmath CAS for prizm" to the fx9860gII because everything is totaly working on this version(integrals, derivaties are not correct on the port by diameter) and because it has a lot of functions that are not on the add in by diameter !
gbl08ma is going to publish the codes of his add in soon, and it looks great !!
I hope you will try to port it to the fx9860gII so that we will have a complete CAS on it !
Thanks a lot

I think it should be pretty simple to port eigenmath to 9860, as the only thing that would be different (as far as i know) would be the input routine. I would assume that all the math routines would pretty much identical.

hey !!
So you mean that the add in is going to work perfectly on the fx9860gII after the port and that all the functions ( diff, intgr, factor) are going to work ?

gbl08ma told me that if these conditions are met (this is what he wrote me):
- GCC is used in place of the Hitachi compiler/Casio SDK (which doesn't seem to have support for big numbers/has some other kind of incompatibility);
- The memory leak bugs in Eigenmath are patched (George Weigt sent me files through email specifically for this purpose; it's in fact just a matter of adding a couple of lines to free memory where he forgot).

his eigenmath add in would be portable to the fx9860gII

Do you think that gbl08ma's eigenmath add in is going to be portable to the fx9860gII ?
thanks for your help !
