* Sound may not set volumes correctly. It is possible that volume of sound effects does not scale properly with distance from the sound source. It is also possible that sound effects are cut off at the wrong distance. This needs further investigation. * Music plays back differently. The DOS music code was not in the Doom source release as Doom used a proprietary sound library. The mus <-> mid conversion mostly works well but some patches are different. By closer examination of which MIDI instruments are used by doom.exe, it may be possible to get a closer conversion. * Savegames may be incompatible on some architectures. Savegames may not be compatible with DOS doom.exe on 64-bit or big-endian systems. On 64-bit systems savegames may be entirely nonfunctional. * Some music which works in Vanilla Doom does not work in Chocolate Doom An example is the music on the title screen of deca.wad. The music here does not seem to be in the .mus format, yet somehow plays in Vanilla Doom nonetheless. Attempting to convert it using the mmus2mid code used in Chocolate Doom results in a crash. * A small number of Doom bugs are almost impossible to emulate. An example of this can be seen in Ledmeister's "Blackbug" demo which shows a bug that relies on the memory layout of the Doom executable.
