Welcome to the software documentation part

I disassembled many syscalls, mainly for the sake of reverse-engineering drivers. You can find here many documentation from Simon Lothar, Lephenixnoir and me about Casio's OS operation.

But be careful, information of this part of the bible is not absolutely sure because some part has been documented with an "old" OS version.

Syscall

Monochrom:

  • [syscall list]({{ site.baseurl }}/software/syscall/index.html)
  • Bfile documentation (TODO)
  • Timer documentation (TODO)

File format

  • [Add-in "g1a" format]({{ site.baseurl }}/software/format/g1a.html)
  • [Add-in "g3a" format]({{ site.baseurl }}/software/format/g3a.html)

File system

  • Old File system (used by USB power Graphic 1/2) (TODO)
  • [Fugue File system]({{ site.baseurl }}/software/fs/fugue.html)

Hardware and software specifics note:

There is all file that I use frequently when I trace syscall and / or find information.
WARNING: Those files are simply note and suposition, so be careful with them !

OS disassembling note:

There is all file that I use frequently to trace syscall and / or find information.
WARNING: Those files are huge because those are a full OS image who have been "objdumped".
