The game will work if you create an ISO and mount the ISO but that requires extra space (to store the ISO) and it is a hassle to ensure that the ISO is mounted (even though DxWrapper can do this for you). Many modern computers (like my laptop) no longer have a CD drive. Instead I am using Dd7to9, which is able to convert the DirectDraw APIs to Direct3D 9. The current solution no longer requires DDrawCompat. However I found out that Diablo also worked fine with the DdrawCompat libraries. There are other patches for Diablo like this one here. The first problem I had with Diablo was that the colors looked messed up on Windows 10. Patch updated: October 13th, 2023 Problem I am using the retail CD version of Diablo, with the latest update v1.09.
