OK, one of the item duping bugs was my fault. What a beautiful consequence of the simplicity of writing games in C. I believe mods are written by disassembling the original game, extending this with your own, custom assembler code, and reassembling it. If anyone feels nostalgic, there's a really good Diablo I mod called The Hell out there. I can't find a good archaeological overview online - perhaps this isn't as well-documented as I assumed. Some of that storyline ended up in Diablo II. I recall that they shipped the game prematurely and simply dropped a large chunk of the storyline full characters, dialogues, items, plot triggers. > is there a hidden cow level in the Diablo 1 source?!ĭiablo I has a ton of lost treasure hidden in diabdat.mpq. I gave it to my brother who eventually made thousands selling those items. And I wrote an IRC bot for keeping track of item trades for some dudes who gave me several accounts full of characters full of really good items. We used IRC for announcing whenever a 'run' turned out to be buggy for a single player. I also never understood what would trigger a bugged game. The mule character could even join another game where it would save, stock up on good items and drop those. This meant they could go back in the game, drop all their items, leave the game, and repeat this while the characters that did save could pick it up, creating copies of good items. I never understood why some games were 'bugged': Certain characters would leave a game and find that their inventory would not save.

I was a programmer on Diablo 2 and used the Diablo 1 source codeĭid you ever work on the problems of item duping on Closed Battle.Net?
