You must have DirectDrawRenderer in the registry set to "gdi" (which is the default) for Diablo to work. If you have changed it to "opengl" at any point then the game will crash after the Blizzard logos.

 for your convenience here is a reg file that will change it for you:

-------------start DDrawRender.reg-------------

REGEDIT4
[HKEY_CURRENT_USER\Software\Wine\AppDefaults\Diablo.exe\Direct3D] "DirectDrawRenderer"="gdi"

--------------end DDrawRender.reg--------------

just copy the date NOT including the dashed lines to DDrawRender.reg and then use

wine regedit DDrawRender.reg

to add it to the registry

First, put the CD in!
If you've already installed it, great. If not, go do that.
Then, do this on the command line:

dd if=/dev/cdrom of=~/Diablo.iso

To mount this image of the CD:

sudo mkdir /media/iso0

sudo mount -o loop ~/Diablo.iso /media/iso0

Using winecfg, add a new drive that points to /media/iso0, and give it the type CD-ROM.
Finally, run Diablo.exe in your program files and you're done!
Whenever you want to mount it again, just do:

sudo mount -o loop ~/Diablo.iso /media/iso0

When you're done and don't feel like keeping it mounted, just do:

sudo umount /media/iso0

If you have any issues still with Diablo complaining about no CD being inserted,
make sure the iso mount point you made is configured as a CD-ROM device in winecfg,
and make sure you have already mounted it
first!

~/wine/dosdevices should contain:

(D being the drive letter of the iso image)

d\: (link to /media/iso0)

d\:\: (link to ~/Diablo.iso)

 *ubuntu users can use the commands:

sudo apt-get install ipx

sudo modprobe ipx

sudo ipx_interface add -p eth0 802.2 0x12345678

(change eth0 for the name of your ethernet/wireless card)

The frame type (802.2) needs to be equal for everyone. It is recommended to use ethernet II instead of 802.2. If playing with computers with Windows, make sure their frame type is set to what you have, and not 'automatic'. It may cause issues if you forget it.

to use ipx multiplayer in this game it MUST be run as root

choose the archive for the version you need

inside the archive ddraw-1.x.tar.bz2 there are four folders

one for wine 1.0, one for wine 1.1.0, one for wine 1.1.1 and one for wine-1.1.2

inside each folder is a file called ddraw.dll

find out your version of wine with winecfg

put the correct version of ddraw.dll either in your wine's c:\windows\system32 directory or your games main directory (c:\diablo)

use regedit to import hack.reg with

regedit hack.reg

if you don't import the registry file then the hack will NOT be enabled

if the hack doesn't work consider compiling it yourself from source (see instructions in the archive)

the earliest version of diablo that will connect to battle.net is 1.07 most cd releases are 1.00/1.01

you will need to manually update to 1.07 to connect to battle.net

as battle.net will update you to the latest version anyway it makes sense to manually update to 1.09

this also applies to the spawned version
