Sharp PC-G850VS Reflashing?

[toml_12953]

The ROM of the VS model (not the V model) is in Flash memory which means it can be changed through software. Does anyone know how? My goal is to translate the STAT and BASE-N menus to English. This should be doable as long as the computer doesn't do a checksum calculation on the ROM. I just need to know how to get the code out of ROM and rewrite it after I change it. If I can do it, I'll make the ROM image available to anyone who wants it.
