Many of my old games require emulators or tools like VDMSound or DOSBOX. This is where I try to explain how they work and provide a link so you can download them.
This is really a venerable DOS emulator and runs so many games so well.
Whenever you launch DOSBOX, the first thing you’ll see is that you’re in a Z: directory. What you need to do is assign the C: drive to the place your game is located. In Windows it’s easiest if you just put your game somewhere easy to get to, like C:\GAMENAME. Then you would type
MOUNT C C:\GAMENAME
If you’re comfortable finding directories then go ahead and move the game wherever you like and use the correct pathname.
On a Mac in OS X you can put your game directory in your user account directory and type
MOUNT C ~/GAMENAME
I have a Games directory with other game directories under it. For me to run old school DOOM, I type MOUNT C ~/Games/DOOM.
After you’re done mounting the drive, type C:<enter> and you’ll be in the directory. Type DIR<enter> to see what’s in the directory. If you see an EXE file then you’re probably looking at the game executable. Type that name and press Enter and it should run. (Example: DOOM.EXE).
Sometimes there are SETUP.EXE programs in the directory that let you configure your controls and sound. As soon as DOSBOX starts up you’ll see a line that says “Z:\SET BLASTER=A220 I7 D1 H5 T6″. This means your sound port address is set to 220, your interrupt is set to 7 and the DMA is set to 1. If you don’t hear sound in the game, run the SETUP.EXE and set the game’s values to these.
This is a Windows-only sound emulator that runs under NT/2000. The reason most old DOS games don’t run is because of sound problems, not really many other reasons.
VDMSound installs as a context menu addon for Windows Explorer. When you want to run an old DOS game, find the game’s EXE file, right-click it and choose from the context menu “Run with VDMS”. It’s that simple.
