motivating purpose being that of capturing in-game MIDI music through software while taking advantage of Windows NT's 16-bit subsystem virtualization. It became open-source and moved to SourceForge after a full rewrite in the early spring of 2001. It was discontinued in early 2004 (last checkin occurred on 2004-02-14), when additional improvements in emulation were no longer possible due to limitations in the Windows 16-bit subsystem. The sound emulation code from VDMSound has since been integrated into DOSBox. VDMSound was not compatible with Windows Vista, making the project obsolete. The current version, 2.1.0 beta, will remain the final version. References External links Windows emulation software
