Initial searches for strings related to 'Diablo II was unable to detect a Disc in your CD-ROM drive' and MessageBoxes with the title 'CD-ROM drive error' with Olly and W32Dasm revealed that the address is around the following block:Ĭode: Select all 0040122D |. When I opened the Diablo II.exe with File -> Open in OllyDbg, the base address is the usual 00400000, and Entry address is: 004014E3. I'm not a beginner, but not pro either.įirst I scanned the exe with PEiD to see if it was packed, and PEiD just said 'Microsoft Visual C++ 6.0', which from some research means that it doesn't have any packing, it was just built with MSVC6. I've been working and digging around the Diablo II.exe for 1.09b for about 10 hours now, also learning more about reverse engineering along the way.

So hopefully this post doesn't get locked or deleted.Īnyways, on to the content. Onyx and other mods said in other posts that since Blizzard introduced the 'no-cd patch' in 1.12+, that basically means that we can also make our own no-cd modifications for previous versions. I've been trying to make modifications to Diablo II.exe for 1.09b in order for it not to use the CD.
