thanks guys will look at the Bryan's UAV mod. I know what your saying about being pure, that's why I wasn't keen on the RGB mod. ive already done one 2600 and done the same trick with the external box approach. the reason I'm asking is that I'm selling the first 2600 to a friend and just wondered if things had moved on from the Longhorn mod and the fact the guy selling the Pal mod here in the UK doesn't seem to be about anymore.
