Here is a fix for the random crashes caused by fast computers :
As mentionnend by Swordfishbone ( http://www.gog.com/en/forum/sanitarium/random_crashes/perm=15/#p_b_15 ), you can download the MS DirectShow SDK CPU Grabber at this link : http://www.reocities.com/kulhain/cpugrab.zip
It is a little app to slowdown the computer, but if you don't want to open it each time you play the game, you can use a bat file and a vbs file :
Start.bat file (optionnal name) :
START cpugrab.exe
Enter.vbs
Start.exe Sntrm.exe /WAIT
taskkill /im cpugrab.exe
Enter.vbs file (optionnal name) :
Dim oShell
Set oShell = WScript.CreateObject ("WScript.Shell")
oshell.sendkeys "~"
So, you put the Start.bat, Enter.vbs and cpugrab.exe in the game folder and make a shorcut to the bat file (example : D:\Jeux\Sanitarium\Start.bat)
What the bat file does is to open the programs and close them. The vbs file is used to hit the enter key to start the cpugrab.exe
It may be used for other games as well.
And thanks GOG for your wonderful games !
