This is all very interesting! I will PM you in relation to your community server - it would be great to engage with other like-minded individuals.

You're very correct in respect of the non-standard sector copy protection SubLOGIC used, but they can be made to work with DosBox. I have them all working with MSFS 2 in DosBox (except SD12), including the very tricky Disk 9 (the one floating around the internet 'works' but has serious problems).

There are other faithful emulators like PCE and 86Box that will run images of the disks including the non-standard sector copy protection so these are a bit easier but like on my actual hardware (physical 5.25" disk, floppy drive, MS-DOS 6.22 etc), an image of my physical Scenery Disk 12 won't work on these. I assume there are two possibilities - I have a bad SD12 disk or it was never made to work with MSFS 2.

I've replied to your PM with all of the details, if anyone else is interested also let me know. The physical version we have is for IBM and is requires either 'Microsoft Flight Simulator or SubLogic Flight Simulator Program' so its safe to assume it will work. I also have an ADF file for disc 12 which appears to be different in origin than the link you posted. Maybe it'll be of some help?

All the best

Scenery Disk 12 was one of the last, if not the last scenery disk to be released, around 1988, after MSFS 3 had been released. It includes renderings of New York City, Boston, Halifax, Montreal, Philadelphia, and Hartford.

It wasn't released for many of the platforms that had received scenery disks in the past, but I do know it was released for DOS and the Amiga. This makes the DOS platform (IBM and compatibles) one of the few (if not the only) platforms to be able to run every scenery disk released.

I ran FS-II on the Apple //e and it's possible that SD12 was never released for the Apple (?) Anyway, by 1988 I was getting less interested in flight sim and more interested in girls, so it might have been released for the Apple and I just didn't know about it.

I started with FS-II in 1985 at the age of 12 and I'd say I flew it...and WW1 flying ace subgame...pretty regularly from 1985-88. Then I picked up FS4 and ran it on my 386SX/20 back in circa 1991. Later I got a 486DX2/66 and ran FS5.0/5.0a/5.1

I never had FSW95. Went from FS4--->FS5---->FS98 and on to today.

Yeah it was a neat scene then, AMD came out with their 386DX/40 which was considered strange in my circle at the time. A 40mhz clone of a 386, made by AMD.
