Vhex disassembler
Vhex is a GUI, Vim based, disassembler for fx9860g. The Casio's OS code is not open-source but we can read the binary for understand his working. There are in particular the syscalls, OS's functions that can be called as a library since the add-ins, which are a gold mine of clues about the functioning of the material.

Building
Before compiling for the first time, There are a few dependencies:
- A suitable GCC toolchain in the
PATH
. You can absolutely not build Vhex with your system compiler!sh3eb-elf
is strongly advised. - g1a wrapper to generate the Casio header.
- P7 communication utilities.
To compile the project, you just plug the calculator and execute:
% make
% make install
