Xbox VGA Bios modification help needed!

Hi,

Thanks for the results.

Sorry about the focus part. I mixed up the hex string from a 100% stock kernel image and the one from Frosty's mod. I corrected both strings in my previous post. You should be able to find the first one in a Frosty modded kernel image just as originally intended.

And finally, was there ever a hacked BIOS based on 5038 kernel? In any case, the hex strings above should always be present in all kernel images (except maybe those related to focus in very early kernel revisions).

 

The Hex editor found the string this time! Replaced it, repackaged the Bios and flashed it.
The result is a green tint in 480p mode and a purple tint in 720p mode. Strange thing is the red and blue signals are present without sync and the green signal isn't present at all! On the green line there's just the sync pulses present.
But why does it show a green tint when there's no green signal?
And why does the behavior change to a purple tint in 720p when there still is no green signal.
