Thanks for your reply, I appreciate it. Yes I have NTSC mode enabled. Yes I have 720p on the Microsoft dash and yes I've been running my current dashboard in 1080i (xbmc) as well as other EMU's in 1080i using a component cable for almost 3 years. I look in advanced mode settings on CoinOPS IGNITE R5 and it does say that 720p is enabled yet it's running the SD skin and in 480i. Very puzzled! Just an update to this, I took the files over to a friends house who also has NTSC enabled XBOX running at 1080i through component and a 32" 1080p set, created a new directory and copied all his mameox roms into it with the CoinOPS IGNITE R5 files, again the same problem! Can only get it running in 480i. Maybe something is mising from my file list, can someone please PM me a link for CoinOPS IGNITE R5 as I got my copy elsewhere, which led me to this site.
