Never_Again Posted March 27, 2015 This feature was introduced following my bug report on OTTAWAU E1M1. This is one of the many WADs that have two-sided linedefs without second (back) sidedefs, e.g. FOREST30 E2M5 (an early version of the above map), INDYJONE, FEZ1 and even Speed of Doom MAP23 that crashed Prboom-plus' software renderer before this emulation was implemented. PROBLEM Recording on such maps with Prboom-plus with Missedbackside Overflow emulation set to YES* and default memory emulation** setup will produce demos that will desync in vanilla (and Choco). SOLUTION · Add -setmem dosbox to the command line OR · turn off Missedbackside Overflow emulation Two demos demonstrating the above are attached. --- * - corresponds to "-set overrun_missedbackside_emulate=1" in the demo footer ** - "-setmem dos622", implied if you don't specify "-setmem"for25des.zip 0 Share this post Link to post
