FS2004, in regards to that question there are thousands of downloads for that platform. Most FS2004 if created within the last 4 months or so do function in the FSC AND FSX ACCELERATION platform of course realizing that that graphics and applications may not function perfectly as intended. I have approximately 5700 aircraft and 2450 are in my sim for use. In you want them when you do a search insert fsx downloads fs 2004. Most sites will have them and if so they can be found on each sites search engine. If there's a hello or fixed wing that I want I'll check it out, if it isn't quite what I expect I'll note the aircraft and keep checking. There's a few sites that have nothing but fs2004. I'd identify them for you but that would take the thrill out of the hunt.
