LeapFrog Pollux Platform: sdlDoom
This is a quick tutorial on getting sdlDoom up and running.
You will also need the SDL libs/headers on your host PC
sdlDoom Preconfigured (git repo) Just compile.
Configure and Compile
Download and extract the source files.
You'll need to fix some button mappings edit doomdef.h
#define KEY_ESCAPE 109 // 'home button' #define KEY_ENTER 120 // 'brightness button'
To get sound working a bit better as there is a possible sample rate issue, edit i_sound.c and change line 56:
#define SAMPLERATE 44100
Make sure your Build Environment is set up and run the configure program then make. Change -j5 to reflect the number of cores on your cpu +1:
./configure make -j5
Copy the doom file to /usr/bin on your device
Copy the wad file to a folder on your device, somewhere like /LF/Bulk/doom on the Explorers or /Didj/doom on the Didj.
This will allow control for all things but shooting, to configure we need to make a config file.
Browse to the folder where you put the wad file and make a blank text file called doomconfig:
# echo > doomconfig
Run doom, using the following on the command line:
doom -config doomconfig
Load a new game, run around and pick up something (not sure if this is entirely necessary), go to the menu and save the game, doomconfig should now be populated.
Edit doomconfig, change these 2 lines to the following:
key_fire 97 key_use 98
Alternatively you can copy and paste the following into your doomconfig file replacing anything that's in there, A= fire, B=use, R should = strafe right, weapon switching doesn't currently work, nor does strafe left or backwards:
mouse_sensitivity 5 sfx_volume 15 music_volume 15 show_messages 1 key_right 174 key_left 172 key_up 173 key_down 175 key_strafeleft 99 key_straferight 114 key_fire 97 key_use 98 key_strafe 184 key_speed 999 use_mouse 1 mouseb_fire 0 mouseb_strafe 1 mouseb_forward 2 use_joystick 0 joyb_fire 0 joyb_strafe 1 joyb_use 3 joyb_speed 2 screenblocks 10 detaillevel 0 snd_channels 3 usegamma 0 chatmacro0 "No" chatmacro1 "I'm ready to kick butt!" chatmacro2 "I'm OK." chatmacro3 "I'm not looking too good!" chatmacro4 "Help!" chatmacro5 "You suck!" chatmacro6 "Next time, scumbag..." chatmacro7 "Come here!" chatmacro8 "I'll take care of it." chatmacro9 "Yes"
This will give you 'fire' on the A button and 'use' on the B button
Other buttons either don't work or don't work as expected if you try and change them via doomconfig, doomdef.h or m_misc.c (defaults get defined here if the config file isn't found), not sure why its behaving like this.
