Hi,

i want to turn on lcd and send debug messages from eboot on ce6.
which files are necessary for mainstone. any sample ?

Thanks

Orko,

Are you talking about sending the messages to the LCD? That's going to
be hard to do....
But if you want to enable LCD and put something there like a BMP or
color, you will have to enable a small LCD driver and send data
directly to the frame buffer. So you will need to strip all WinCE and
GWES specific functions from the WinCE driver and port it to EBOOT.

Hi Orko,

Sample for you. We also have shown BMP file / image loading process bar
/ and debug message into screen......If any more problems, feel free to
discuss.
