Well...a long time ago, I was thinking about writing some games for DOS, and my PCGPE docs indicated that the VGA card had a feature that lets the system use 128k VRAM at a time. Maybe the game uses that feature. Does the game work on other systems that use that config?

For the longest time I couldn't figure out why the orignal game would work fine but Special Edition wouldn't run the installer or the game on my K6-2+ 98SE/DOS machine. After a bunch of experiementation, I narrowed it down to the game not working if I=B000-B7FF is is set as an included memory range for EMM386.

I'm curious if this is a quirk in my system or if this is more generalised, has this happened to anyone else?

Yes, this sometimes happens on some computers. Usually, installing B100 (B200/B300/B400) instead of B000 helps.

Yep. I've been using B400 on my K6-2+ system and it has far fewer compatibility problems. Most likely B100/B200 would also be OK, but I already have enough UMBs as it is.
