ᛞᚨᚱᚹᛟᚾᛞ: Don't forget they're targeting Windows 95, which was
not exactly the best for DOS. SimCity 2000 demanding VESA or better drivers, Wing Commander needing special memory tricks, System Shock controlling like a computer workstation on wheels...oh, and Hades help you if you want a joystick.
Hehe. Maybe I remember it being worse than it was, but yes, Windows was also fun with drivers and blue screen of death (I think I sneezed so hard once I shook the table just a tiny bit and the computer blue-screened itself out of the room). 98-ME and eventually XP was better an more stable, but yes, since Win95 was built upon DOS it would've been better to boot back into DOS mode again since it used up a lot of the remaining resources. Dune 2 f.ex. wouldn't run properly either otherwise.
Falcon 4 also needed to have a special memory boot-up sequence. And in those days we didn't have internet, let alone lots of magazines about this stuff. At least not here in Norway. All that time I spent getting the game to run (had to phone a friend) and the disk eventually had some troubles with a few sectors. Nothing lost actually because I remember the game to be excruciating boring. XD
Right, joysticks. Bought a complete package with Descent, 3D card, sound card + a joystick. I gave mine away eventually and haven't touched one since (outside of arcades that is). Wasn't worth the trouble. Nowadays I just plug in a controller via USB and it just sticks.
Speaking of Heretic HD, Hexen has something similar via GzDoom:
