→Ultimate Doom and Doom II: reduced player bob (check the source)
* Four new menu graphics lump are present: M_ACPT ("accept"), M_CAN ("cancel"), M_EXITO ("Are you sure?"), and M_CHG ("change game"). They have been inserted in between the DEMO2 and DEMO3 lumps in doom.wad, and placed at the very end of the file in doom2.wad.
* The engine seems to ignore the [[sound]]s' sample rate, and instead use a fixed 11025 Hz rate. The "item respawn" sound(<tt>DSITMBK</tt>) and some [[super shotgun]] sounds (<tt>DSDBOPN</tt>, <tt>DSDBCLS</tt>, <tt>DSDBLOAD</tt>), however, are still sampled at 22050 Hz; therefore when they are played back they are slower than they should be.
* The player's bob is reduced by 25%.
