ADDITION: As Kekko helpfully posted below, full Voodoo2 emulation is not implemented in the current code. However, the list of DOS Voodoo2 games does not include any which are Voodoo2-specific:
Voodoo 2 DOS Glide compatibility matrix

In fact, apart from performance, the list includes just two games which take advantage of the Voodoo2 device: GTA and Shadow Warrior. Both will function at a higher resolution using this device. My hope is that the attached test build can enable the higher resolution in these two games, and therefore provide all the major benefits of DOS gaming with a Voodoo2 (excluding performance). When testing, it may help to try a copy of glide2x.ovl from the Voodoo2 driver set, in addition to the one already included with Daum's build.

[IGNORE THIS PARAGRAPH] It appears that Kekko has kindly provided a virtual Voodoo2 (edit: Voodoo1) device for DosBox. It has been activated in the attached test build, which is a modified Daum build. However, I have no games to test whether it is truly functioning as a Voodoo2. Please verify, and if it is, then it may be possible to expand the video memory further. [\IGNORE THIS PARAGRAPH]

It is strongly recommended to newly install Daum's build into a directory and then overwrite with the files contained in the attached ZIP. The executable may be renamed to DosBox.exe. The five DLL files are required. Note that the fluidsynth and SDL_sound libraries are not active. I would mainly test with this configuration: fullresolution=original, output=openglnb, voodoo=opengl, glide=emu. The fullscreen option may be set to true or false.
