[maemo-developers] [maemo-developers] Nokia SDL color format for pixels

Well, there is a open source system for home automation - Plutohome (
www.plutohome.com). This system can use Nokia770/800 as a control panel -
Orbiter. The Orbiter is based on SDL. So, after some hack it started work on
Nokia (os2005/os2006) but there is a problem. Icons on the Orbiter should
change their color according to some events. Initially they are pink. Using
SDL functionality their color can be changed. It works fine for Debian but
it didn't work for Nokia (either scratchbox emulator or real device). All
icons are pink every time.
I'm not developer. I'm integrator. So, it's difficult for me to understand
where is the problem. Have a look attached files. Maybe you can help me.

Thanks in advanced.
