Your welcome Garsh,
This is also available but I have not installed it.

It seems to be the newer project from Nokits or the team behind Diablo HD MOD, Belzebub and Tchernobog.
I am unsure if you or anyone needs to know that it should be possible to use a Virtual Machine of an older Windows version with Linux or a newer Windows version to install the older Diablo games without HD resoultions. Be careful with Linux and Wine as it is a security risk, it's a potential door that some people might leave unattended according to Linux security users.
I do not use Virtual Machines (paid or free), but have looked into them a little bit. There is a learning curve, but they have certain security benefits and should operate as the older OS. For example you might have some troubles with drivers or newer and certain hardware that think you have all of the older DirectX files but do not use them or will not install them, even with a virtual machine.
The Hell 2 is in beta and the designer said with each update be prepared to lose everything you have saved. Until version 1.x.
I cannot get the Diablo 1 or Hellfire expansion to recognize the ISO image, even on a CD-RW. That would be interesting.
https://www.moddb.com seems to have legitimate Blizzard patches. The 1.09 worked with Diablo 1.
Since you got it working do you have this old Diablo/Diablo Hellfire guide?
https://archive.org/details/Diablo_Hell ... f/page/n49 It helps to plan out the quests and automatic skill increases to get your maximum stats. I think at level 60 in those original releases you are able to move the stats around too, I do not remember. It is technical but helps understand the game.
