If you don't mind me resurrecting this old post, I finally managed to get this game working.
Problems are the following:
- SETUP.EXE installs regular EF2000 under Windows or DOS, but not EF2000 optimized for Rendition or 3Dfx.
- EF2000 optimized for Rendition or 3Dfx won't install under modern 64-bit Windows.
The solution is simple, use a program such as Virtual PC, VMWare or VirtualBox and Windows XP to install both regular EF2000 and / or EF2000 optimized for Rendition or 3Dfx. They're both for DOS, so you only have to move the installation folders outside the virtual drive afterwards.
Now, to run EF2000 v2.0 from DOSBox:
- Regular version: Mount the installation folder and mount the ISO or CD-ROM, run EF2000.EXE from your install folder.
- 3Dfx version: Just the same thing, but you'll also need to set up Taewoong's build of DOSBox, version Jan. 3. 2015 or newer and these two options: glide=true and memsize=63.
And that's it.
