I think if that could be done it would be great. I don't know the national cricket broadcasters for most countries, but I know Australia, England and Wales, and New Zealand's. I've written them below.
Australia: Channel Nine Network
England and Wales: Channel Four
New Zealand: Sky Sport New Zealand
aussie1st has already made a Channel Nine Network patch, DANNY79 has already made a Channel Four patch but someone needs to make one for Sky Sport New Zealand, plus the other countries.
Sam would need to edit the .exe to allow this, so if anyone could give him a nudge that would be great. I haven't a clue about this sort of thing. Sorry!
Oh, guys, please post in my pitch mats thread! I will be releasing the first version of a pitch mat pack soon!
Nice idea, I can't wait for the Sky Sports 2006 graphics though.
