I don’t know if this is allowed (or even legal, actually. Best look it up before attempting) but as BMS still uses a lot of the old Falcon 4.0 core (e.g. TrackIR software still recognizes Falcon BMS as Falcon 4.0), wouldn’t you be able to somehow trick Steam into thinking your playing Falcon 4, while you’re actually flying in BMS?
Nope. Steam is just looking for the exe name. You would need BMS exe to be renamed and also in the directory. Actually, the directory part you could trick it into doing, with junction links (SteamMover app does this automatically for you in fact). The renamed exe not so much. If you desperately wanted steam to track the hours the sim was running, and the built in logbook was not good enough at doing that (seeing as it ‘only’ tracks 3D time), you could create a script which starts BMS up, and then stays running until BMS is closed, and make it an exe file - and rename it to falcon4.exe, so that steam thinks that its running the game.
But as above, its a bit pointless, really. You want a logbook that tracks less time, not more.
just my two cents about this topic: I think it would be the time to create a team to work on this project just as it deserves to.
I want to clarify that this is not an original point of view of mine, but I’m reporting it here because I believe it’s a very good point to start from to make such kind of matters become real.
My apologies in advance in case I bothered anyone with this mine.
add -ef switch to your BMS launcher shortcut command line, launcher.exe -ef
In the setup/controlers/advandced tab, enable external mouselook.
In 3d world press CTRL+Z ( if Ctrl-Z does not work, try Ctrl-i) then F, then press (3) and you have free floating cam view. Move camera view with mouse move. There are couple of threads on forum on this topic. Hopefuly it will work. Just in case, Forum Search is your best friend if above does not work.
