What DOSBox Optionals is

DOSBox Optionals is a Windows-targeted emulator forked from DOSBox for MS-DOS, Windows 95, and Windows 98 software. Its video options include Surface, OpenGL, and OpenGL3 backends with shader support. Extended 3Dfx graphics can reach resolutions up to 8K, depending on DOSBox resolution. It can start on another monitor, including a third, and can manage, mount, and create hard disk images up to 8 GB. Listed audio support includes MAME sound, FluidSynth, Munt MT-32, Nuked OPL3, and SSI-2001 reSID emulation; it also lists several audio formats for decoding in CDR-WIN cue sheets. For Windows 95 and 98, the README lists IDE support and virtual-mode CD-ROM emulation. Networking options include Novel NE2000 and IPX mode. Listed memory limits are 1 GB for Windows 98, 512 MB for Windows 95, and 256 MB for DOS. The libraries are integrated into a single DOSBox.exe file, and the archive includes Lite and Heavy Debug builds. The project is free, and source is available.
