Game data - WADs
----------------
(This section is aimed at people not familiar with Doom and the
data files it uses.)
DS Doom is a game engine - it provides a program to play Doom levels, but
it doesn't include any levels itself. More importantly, you need all the
sounds, sprites, and other graphics that make up the Doom environment.
So to play dsdoom, you need one of the main Doom date files from id
Software - either doom.wad, doom2.wad, tnt.wad or plutonia.wad from one
of the commercial Doom games, or the shareware doom1.wad. This file
is called the IWAD.
If you don't own any of the Doom games, get the doom1.wad from shareware
version of doom on The Dos Games Archive. You won't be able to play most
add-ons.

Now included in this archive
Installation
------------
Simply extract the zip to your favourite media device, dsdoom will now read
files from the directory where you put dsdoom.nds when the launcher supports
the argv protocol. For a launcher that supports argv and works on many devices
see http://devkitpro.org/hbmenu. Select Standard Game from the initial menu to
start a single player game.
Using the latest hbmenu you can use .argv files to pass arguments to DS Doom
which gives you the ability to use any PrBoom compatible PWADs and DEHs.
DS Doom will accept most arguments you can pass to PrBoom but we offer no
guarantees that all of them will work as expected. Here are a few of the
PrBoom arguments you can pass.
WAD Options
-iwad iwadname
Specifies the location of the IWAD file, typically doom.wad or
doom2.wad (or doom2f.wad). This tells prboom where the main .wad
file that came with the version of Doom that you own is.
-file wad1 ...
Specifies a list of PWAD files to load in addition to the IWAD
file. PWAD files modify the existing Doom game, by adding levels
or new sounds or graphics. PWAD files are widely available for
download; try ftp.cdrom.com/pub/idgames for starters.
-deh deh_file
Tells PrBoom to load the dehacked patch deh_file.
Game Options
-loadgame {0,1,2,3,4,5,6,7}
Instructs PrBoom to load the specified saved game immediately.
-warp { map | epis level }
Tells PrBoom to begin a new game immediately. For Doom 1 or
Ultimate Doom, you must specify the episode and level number to
begin at (epis is 1 for Knee-Deep in the Dead, 2 for Shores of
Hell, 3 for Inferno, 4 for Ultimate Doom; level is between 1 and
9). For Doom ][ or Final Doom, you must specify the map to begin
at, which is between 1 and 2 (0 for German Doom ][).
-skill n
Tells PrBoom to begin the game at skill level n (1 for ITYTD, 2
for Not Too Rough, 3 for Hurt Me Plenty, 4 for Ultraviolent, 5
for Nightmare).
-respawn
Tells PrBoom that monsters that die should respawn (come back to
life) after a while. Not for the inexperienced.
-fast Tells PrBoom to make all the monsters move react faster. Not
for the inexperienced.
-nomonsters
Tells PrBoom to include no monsters in the game.
Controls are simple.
Use the directional pad for movement.
Hold the X button to sprint.
The Y button toggles through your weapon inventory.
The A button fires.
The B button is the "use" key for opening doors, etc.
The R and L buttons allow you to strafe.
The Start button brings up the main menu.
The Select button chooses options in the menus.
Hold B and press L or R to zoom in and out on the automap.
Press Start and Select at once to alter console mode.
Configuration
-------------
DS Doom automatically creates a PRDOOM.CFG configuration file, using default
values. Options set in the setup screen will be saved automatically.
A couple of DS specific variables can be manually edited:
gen_screen_swap (0/1) - Setting this to 1 swaps both DS screens
gen_console_enable (0/1) - Disables automap and shows console window
gen_cheat_enable (0/1) - Enables Cheats (god, all ammo/keys).
As for now, there are a lot of 'garbage' options which can be altered
but will not be used in the main game. These are originally used in PrBoom.
WARNING - don't try to delete one of those entries, dsdoom won't start!
Wifi connection
---------------
To play online using wifi, you're going to want to have a PC with port 5030
opened/forwarded. Run prboom_server.exe with the number of players specified
using the -N command line parameter. There are other parameters for such
things as maps and coop; check out the prboom_server documentation. The
server waits until the given number of players connect and then the game
begins.
Now that you have the server running, you will want to set up the DSes. Make
sure that WFC data is set in firmware on the DSes. Next, edit the prboom.cfg
file on the card and change the server "name:port" line under misc. You are
ready to start. Launch dsdoom.nds and choose the network game option in the
initial menu.
