I know you would need a ROM image, can we get that?
i think that martin had a thing for rom dumping on his site.

2. It is not possible to write an emulator that uses that casio programs until we know ALL features of the hardware EXACTLY. else they won't work. so you'll still have to discover a LOT of things. In my mind it is
NOT possible till now.

We don't know what methods the cas OS uses we don't know.
We don't know bugs of the calc that may be used by the OS. etc ...
You should be an excelent hacker to figure this out in order to make an emu 100% compatible with the casio OS.

I know about uP, because I study electronic engineer, i hope that this information help to this topic. If you have any doubt, i will investigate about that topic and tell you by this forum.

The problem are the hardware interrupts that are made by the bios. In fact all you do writing an emulator
is to rewrite the bios and its interrupts but we know to few of those to do so. THis is the problem. I believe
,and have also tested it for some, that the AFX has interrupts for basic file use, com-port etc ...
The problem is that if these interrupts are set up by the bios you MUST rewrite them in order to make the
System work with the casio programs. For the comport you would have to use a Pipe through which another com programm will comunicate and so on. Thats pretty difficult.

Whyp is dooing an emulator, he arrived to launch code but not booting the calc, mastermage arrived to same point.
I found on the internet a machine emulator : MESS (mame version for machine) but i don't know how to add a machine...
Yea it is complicated because we must emulate RAM and processor (quite easy) but after you have the screen, the flash, the ROM, Interuptions and I/O ports to control !
The screen is esay to emulate, the flash and rom is ok aswell but eh I/O ports are difficult to emulate because we don't really know how they work lik ethe interuptions to execute and when !
So i think I answered to your question...

I think that they must give tools for the calculator use, I dont know very well if other companies like TI or HP do it.
