According to the YouTube video at https://www.youtube.com/watch?v=x7Hi5UMhkuQ
1. Do not use Windows compatibility settings when you install.
2. Install the patch from 1998.
If you download it from Patches-Scrolls, it will be called bdpatch.zip.
It will unzip to BDPATCH.EXE
Copy the BDPATCH.EXE file to the game folder before running it.
Don't use the Windows 10 compatibility mode.
Only use the compatibility in DxWnd.
Follow the YouTube uploader's instructions for setting up DxWnd.
DXWnd settings below, sorted by tab:
Pos & Size = 0,0 - 1280 x 960
Hide multi-monitor config - ON
Cursor Visibility - Hide
Slow down mouse polling - ON
Version Hook - DirectX1~6
Emulation - Automatic
Fake Version - Windows 95
Set single core process affinity - ON
No compat settings on installer or game executable
If a setting is not specified, assume it uses default values
Also tried within VirtualBox running XP-nada.)
1. This was not an XP game. Even Inferno had to tweak settings when she ran it on XP, and that was an early version of XP on a real computer, not VirtualBox which doesn't fully emulate every aspect of a computer -- especially not an older one. ***Inferno's XP Setup for Black Dahlia***
If you're trying to use a virtual machine, be sure to disable virtualization technology (VT) in the computer's BIOS/Setup if possible. https://en.wikipedia.org/wiki/Intel_VT
VT is to make the virtual machine run faster, which is absolutely not what you want with a game from 1998.
You may want to try Inferno's suggestions for XP if you're using an XP Virtual Machine.
Virtual Machines used to work great, especially with Windows 98, but not so much anymore. Unlike DOSBox, VirtualBox and VMware don't control for speed.
3) have seen board comments elsewhere where after install, you change compatibility setting (uncheck something)...any thoughts?
If you want to use Windows compatibility, don't use DxWnd.
If you want to use DxWnd, don't use Windows compatibility.
You may have to "Run As Administrator" on Windows 10 to get the game to install at all. Best not to if possible.
You may want to install to a location other than C:\Program Files or C:\Program Files (x86)
You find a lot of "solutions" online. They won't all work for everyone's computer. What worked on a computer 5 years ago may not work now. You have to experiment and see what works for your computer.
