Hi all,

I've noticed that there are many implementations of English WM6.0 and (working on) WM6.1...

I would like to create or modify the language and beginning to study the structure, to make an ITALIAN rom.
The roms linked on NEWPLOWE site are in english

[email protected]@p://fsc.newplowe.com/download.htm

and the extension of those files are .nbf
So just to understand the beginnings...

1 - How can I open, disassemble or simply view that rom, I've tried with htc64.exe but returned a message like that:

the ROM is for an unknown device, be carefull", then if I insist: "unable to decode ROM file".

2 - Can someone help me please to discover how to cooking rom, linking
some document to read?

Thanks in Advance...
