DOOM DOSBox Setup Tutorial

GETTING STARTED:
First off, you'll need to download dosbox (duh).
http://www.dosbox.com/download.php?main=1

Once you've set that up, you'll probably want the DOOM executables. We'll get to that in a moment.

SETTING UP YOUR DOSBOX:
[if you already have DOSBox set up, skip this part]
Next, you'll want to get a good configuration going.

First thing you'll want to do once you have dosbox set up is to allocate a folder to it.
Go to your main C:\ drive, and make a folder there named whatever you want. For example, we'll be using C:\dosgames\
Now, once you've made that folder, open up DOSBox Options. It should be in the start menu OR in the main dosbox folder.

Now that the options are open, go to [autoexec] and put this under it:
mount C C:\dosgames\
C:
cls
dir

This will make it so that, automatically, whenever DOSBox is launched, it will run these lines.
Let's break that down, though, since I'm assuming you have never used DOSBox before.

mount C C:\dosgames\

Should be obvious enough. Mounts the VM's C: drive to C:\dosgames\.

C:

Changes to the C: drive.

cls
dir

Clears the screen, then shows the directory listing. Ez stuff, eh?

Mess around with settings as you please, but here's (some parts of) my config.
[sdl]
fullscreen=true
fulldouble=true
fullresolution=1280x800
windowresolution=1280x800
output=overlay
autolock=true
sensitivity=100
waitonerror=true
priority=higher,normal

[dosbox]
language=
machine=vesa_nolfb
captures=capture
memsize=64

[render]
frameskip=0
aspect=false
scaler=none

[cpu]
core=auto
cputype=auto
cycles=max
cycleup=1000
cycledown=1000

Just tinker with 'em. See what works. It's what everyone does.

SETTING UP DOOM:
Now that you've messed with that and set up DOSBox, it's time to play doom!
Of course, you need to download DOOM:
Since I'm a fucking nerd who likes old versions maybe a bit too much, this download includes the original v1.0,  v1.9, and Ultimate versions of DOOM.

And finally, put it in C:\dosgames\doom\, then run DOSBox, and you're good to go!

For navigation, use cd directory
example:
cd doom
cd 1_9

You can use cd .. to go backward.

For listing the files in the current directory, use dir

For running any executable, just type in its name.

So, to run DOOM 1.0, you'd do
cd doom
cd 1_0s
doom.exe

Use the SETUP executables to set up controls and such.

If there are any problems, please report them to me in the thread/via email/via IRC.
