Ok i finaly did it
after making my own cable i decided to try the HD pack mod and it works great, my monitor suports sync on green and have 5 bnc inputs in the back of the monitor, so i got 3 adapters (bnc to rca male) and connected my HD pack (no soldering), now the only thing left to do was pin 11 to 9 switch from the avip to get true vga.
All woks fine but like many some apps and games are green in part, now yesterday i loaded xbmc-2003-10-21 (xbox media center) and from the apps menu i loaded Avalaunch en then tried MXM and they came out perfect (they used to be green)
So my question is what in xbox media center (xbmp from another post also did this) makes things perfect?
Anyways i thought i would share this info in case it actualy helps in the dev of a new bios.
