Hi all, Long time lurker, first time ....... Just got back into the SF2 series and noticed that I can't see a ammunition counter for the aircrafts cannon. How did pilots know the remaining ammunition in real life? is there a mod out there that places an ammunition counter in all the stock aeroplane cockpits? My second question may ignite a few "use the search function" etc responses, but I've been searching and reading the proceedure for a few days and can't nail it; I've been able to get a few mods to work so know my way around the mods folder and file structure for a windows 7 install. I have a merged install for all of the SF2 titles and when I go into one of them and start a campaign it lists all the campaigns throughout all the titles. Is there a way to have the titles merged but play one of the titles as a standalone? i.e. when playing the Vietnam exe can I have the install so that it only shows the vietnam campaign and aircraft pertaining to that title only? thanks
