Diablo 2, and like most computer programs have only a limited amount of possibilites that can happen. You probably know you cannot find a Ber Rune in Normal Act 1, but it's not so obvious that you also can't ever find an Ohm Rune and a Ber Rune from the same chest. When loot drops in the game, a series of calculations occur that involve the documented odds that drop calculators use, but also some intricate inner workings of the software code. This emulator includes both those odds, and the inner workings. Drop calculators ignore the very inner workings of Diablo 2. d2emu also let's you see what the actual drops will look like, which is pretty fun.
