Final NeoDoom version 1.5, compatible with LZDoom 3.8.5, Zandronum 3.0 and GZDoom 2.4.0 - improved multiplayer.
Final NeoDoom version 1.5 recommended engine: LZDoom 3.8.5, which have support for splitscreeen multiplay (it also runs in GZDoom 2.4.0 and newer versions). It also rus with Zandronum 3.0.
To run spliscreen multiplay in LZDoom, you'll need to run two instances of LZDoom 3.8.5 simultaneously, and also reset XINPUT controllers (each controller must have its bindings only on one executable instance). Here follows the CVARs to enable multiple LZDoom instances:
vid_activeinbackground = 1
i_soundinbackground = 1
joy_background = 1
Fake splitscreen works as a multiplayer game, so you must connect each LZDoom instance with one game administrator while the other executables will join the same game. Here follows command line parameters to be added for each instance:
LZDOOM -host 2 (for the administrator)
LZDOOM -join %COMPUTERNAME% (for all other executables)
It is also recommended to set a config file for each instance, using something as "-config %dir%\LZDoom_1.ini", "-config %dir%\LZDoom_2.ini" and so on.
Last information: Final NeoDoom does NOT support gameplay mods such as Brutal Doom or weapon mods; it must be run separately.
