    Some basic offsets to let you play offline

    If someone wants to play D2R (build 62115) offline just patch this in memory:

    0xD4AD68 -> 90 90
    0xD4E25F -> 90 90 90 90 90 90
    0xCAFB9D -> 90 B0 01

    NOTE: This won't let you enter the game with saved chars! Only new character

    How to patch it? Well that's up to you

    "In memory"

    I might be dumb, but these offsets don't seem to be mapped in game's memory.

    Edit: memory is read/execute only anyway, i'm too dumb to work around that

    Thanks for sharing!

    I successfully unpacked/dumped from memory and also patched in memory - process still closes immediately though.

    Looking at the asm of the patched regions it seems I am offset. Could you share the original in memory hex bytes of the patched regions for verification?

    EDIT:

    Was a rebasing issue as expected.

    I see these offsets in debugger when I attach it to a running game.exe but I am not able to change the values there. Can anyone explain how to do this, please? I'd be much appreciated. I've been fighting with it since yesterday afternoon with just a short break for sleep.
    @king48488 are you actually able to get in the game? If so, would you mind explaining how you did that, please?

    I managed to unlock TCP/IP menu with join/host game options. Hosting turns on a loading screen but then goes back to main menu. Joining is just waiting with no error or anything happening. If I host a server in D2 (not D2R) and try to join to it from D2R, the game is loading at first and then crashes the application.

    Another interesting thing I noticed is that if I click 'join game' first in D2R, wait for a second, cancel and then try to host a game, the screen goes black and freezes. However, at that point D2 (not D2R) recognises there is a server open and tries to connect to it. However, I am getting 'unable to join' message after that.

    Could there be also some way to use local multiplayer based on that?

    Can confirm that crc32 bypass works for diablo, seems to be missing a few new offsets for it to work though.

    Feel free to share anything you find with the rest of the community, as I doubt Blizzard will care about improving their tech alpha demos security at this point.
