Emulator:Demul

**** THIS PAGE IS A WORK IN PROGRESS ****

Demul is not available natively for linux; it is also the only accelerated NAOMI // ATOMISWAVE emulator currently available, therefore we will look at the requirements for running the emulator under WINE

64 Bit Systems - FGLRX Configuration

err:winediag:X11DRV_WineGL_InitOpenglInfo Direct rendering is disabled, most likely your OpenGL drivers haven't been installed correctly

Method 1

To avoid the emulator wiping out the xserver when using either of the directx plugins, you need to load the correct 32bit libs. If they are not loaded you will receive feedback from wine stating direct rendering in not enabled.

You can check if the program is going to run correctly by loading it manual through the commandline

1. Start a Terminal
2. Type: wine C:\\emulators\demul\demu.exe
3. Select Config->Plugins from the menus
4. Check the terminal screen, if you dont see the above error the prefix is configured correctly

If you see the above error in your terminal window you will need to set the LIBGL_DRIVERS_PATH variable before execution.

This script will load the emulator correctly for fglrx users

#!/bin/sh
LIBGL_DRIVERS_PATH=/usr/lib32/fglrx/dri/
wine C:\\emulators\\demul\\demul.exe $@

Method 2

Create a symbolic link for the fglrx dri module to the location WINE requires. Doing so, negates the need for the above script

sudo ln -s /usr/lib32/fglrx/dri/fglrx.so /usr/lib32/dri

Demul // Wah!Cade

With the release of Demul 0.5.6, comes a new command line interface. There is the requirement for the system name to be passed to emulator before the romname.

Configuration

To use this emulator with Wah!Cade , 64bit fglrx users must use the Method 2 fix.

Platform	Version	Device	Exec	Type	commandline_format
Linux	0.5.6	ROM	wine	D	<path_to_demul.exe> -run=<systemname> -rom=[name]
Linux	0.5.5	ROM	wine	L	See Below

Demul versions before 0.5.6

Requirements

• Demul Installed, Configured & Running games manually
• AutoHotkey installed under wine winetricks autohotkey
• Demul WINE Loader installed to demul directory
• Demul Launcher INI file installed to demul directory

To have this emulator work with Wah!Cade you will need to ensure the requirements above are met and you have configured the Demul WINE Loader as listed on the Demul WINE Loader page.

Wah!Cade ini settings below

emulator_executable                     /usr/bin/wine
commandline_format                      "C:\\Program Files\\AutoHotkey\\AutoHotkey.exe" "C:\\emulators\\demul\\demul_launcher.ahk launch "[name]"

An example bash script is available on the Demul WINE Loader page
