LouisCyphre: Did that, still crashes. I'm stumped. And I emailed the tech support at GOG and have talked to other Tech-heads too.
Yeah, I'm starting to get to the bottom of the barrel too.
So far, you have:
• Set DOSBox to run in XP mode
• Tried various graphic modes (ddraw, OpenGL, overlay, surface) with Overlay seeming to work the best
• Configured DOSBox so that it stops closing automatically when Blood crashes
• Gathered screenshots of the error
• Upgraded to DOSBox 0.74
• Disabled the Blood's audio
• Limited your CPU cycles
• Changed the amount of RAM
Am I missing anything else you have tried?
For clarification, after following Qbix' advice to limit your CPU cycles, you said it was choppy, but did it crash on you? If you just closed out, you might try just running around in game with godmode on to see if it still crashes on you.
Also, earlier you mentioned that it wasn't letting you configure your 2 mouse button as alt fire. Have you tried running Blood with no mouse at all? You can set this in the blood.cfg file by setting your controller type to 0 (keyboard only):
ControllerType = 0
Also for clarification, When you disabled sound, what method did you use? You can edit this directly in your blood.cfg file by setting the values of FXDevice, and MusicDevice to 13:
FXDevice = 13
MusicDevice = 13
