great to hear that you are still working at the USAF Win7 Fix!!! Did you also have made something new for the good old IAF? I love this old sim too. Have downloaded your fixes for it at GulfKnights forum long time ago, but couldn't find them anymore on my HD. Many thanks for your outstanding work to keep those flightsim icons alive!!
The old Janes series is still one of my favorite. Sadly there are no good solutions for the Longbow Anthology to get it running with W7 64.
I have extra made a second PC with Win98 SE for my homepit to play those old sims, too. This machine has a dualcore AMD 3Ghz and an Geforce GT 6800 AGP in conjunction with an old Voodoo SLI. It's the biggest system I could get W98 SE running on. It's also possible to use nGlide on W98 SE (it's not meant to run on it, but it does perfectly), this way you could benefit from the higher resolutions nGlide makes possible for eg. in Janes F-15 or Longbow. Looks really nice this way. For dogged simulations like the old Digital Integration Front Line Fighters or the Novalogic F-22 Lightning 3, F-16 and Mig-29, which did'nt like nGlide as much (graphical glitches) I use the old voodoo system. For the good old Comanche Gold, thankfully a lot of Graphic Mods exist.
Hope someone, someday could make something like a Win98Box for running those old sims. But I think Microsoft didn't like this idea, otherwise such a solution would certainly exist.
