I don’t know if anyone else, other than your editor, is more than a little wary of the superlatives regularly used to describe add-ons these days, but here’s the latest one… We’ll leave you to decide whether the description is warranted or not.
TDFI Design have upgraded their 737 Ultra Sound pack to become the 737 Extreme Sound pack, promising “one of the most accurate audio representations ever made of the Boeing 737 NG series“. Amongst the features is something that most packs of this type do not include – a 2d pop-up panel that allows control over air con, crew notifications and similar. The package, which can be found here, is only for Windows Vista and later operating systems. It will not work on Windows XP.
