I just stumbled upon this topic last night and now have several of my games working on my VGA monitor that didn't before. Thanks for all the great info.
I took a stab at
Dakar 2 and didn't find any of the usual patterns. However, I DID find the same pattern that's in Scooby Doo and Winback 2:
CODE
8B 48 28 52 8B 50 2C 51
>>
90 90 52 8B 50 2C 6A 00
This gave 480p in the opening videos, but once the videos finish it switches back to 480i... so that was a no-go.
I know it's been a while since there was much activity, but is anyone still interested in this thread?
