i used gizmo, loading the game's .iso file, works every time.
Gizmo's home page. Note that I use the sims 3, not 4.

I'll try to explain with my limited knowledge about emulators and such
When you run the game it might only play in one corner of your screen, I couldn't figure out a way to fix this so I just rolled with it and got used to it after a while.
PS: After you've closed the game it might not have your character saved if you try to run it from Gizmo. If this happens simply go into the drive you mounted Diablo to and run AUTORUN.
If I was unclear please tell me and I'll try to explain better
if you use YUMI there is an option in there to try and add any random ISO to a USB multibootable stick (it's at the bottom labelled as "Try an unlisted ISO"). no guarantees, but I have had some success with random ones
first you'll need to create an ISO from the CD. there are several applications that can do that, I personally use gizmo drive
let us know if it works out!
Second that. Great app. Can I randomly plug a new favorite, gizmo drive. Doesn't cover as many image types but allows for far more active vdrives.
