The DOS Demo both new version (1.1.0.5/WDOSX097) and old (1.0.0.5/CWSDPMI) hangs (almost always with video corruption) and/or exits DOSBox (74/74-3), DOSBox SVN (4483), DOSBox Staging (0.81.1), and DOSBox-X (2024.03.01) when DOSBox is configured for SoundBlaster 2.0 (sbtype = sb2) when the location is selected (or prior) - all other sbtypes play without issue.
Don't know if it behaves the same on a real SB2.0 (don't currently have a SB2.0 configured PC), so this may/may not be a DOSBox SB emulation code bug, but considering many/most folks will likely try this (first) with DOSBox they may run into this...
