[Nomad1-dev] freenomad news, 2002.01.02

[Valters V. <va...@in...>]

Hello folks.

The Freenomad now compiles cleanly under Windows 2000 (using Visual C++ 6)!

Sadly, DeviceIoControl() calls failed on the machine I tested, so I can't say 
it's actually working.  If someone could download the code from CVS, compile 
in Windows and give it a try. You would need to set breakpoints in 
ecp_win32.cpp file and step through the DeviceIoControl() calls, maybe you 
will be able to tell what's going on and what need to be corrected...

Other news - I spend quite some time reverse-engineering Creative's software 
for Windows 98, and well, I did not find any commad it would send to player 
to send file larger than 512kb !

On reversing: the playload file is nomad.ocx. It then loads nomad.dll when 
needed, which internal name actually is 'YEPP'. The nomad.dll will do 
low-level port writes, and nomad.ocx does command/data perparing and has 
these two routines that run "send data" / "receive data" buffer to nomad.dll 
(which does actual port code). I monitored the buffer contents and did see 
nomad commands and data being passed, but I did not see if it would do 
something different after first initial 32 blocks (of 16kb). I did not see it 
sending special command or anyting. 

So, no luck. It would seem that we should be able to just keep send data 
chunks for whole file and player should just accept it. I guess I will keep 
digging.

I am really looking forward trying to run freenomad code on Windows - if 
suddenly it works?
