1. Requirements
|
|
* libsdl1.2 - It is strongly recommended that you upgrade to the latest
|
|
version of sdl (1.2.14).
|
|
* scons - Required to build fceux.
|
|
* libgtk2.0 (optional) - recomended that you install version >= 2.18
|
|
* libgtk3.0 (optional) - this compiles as of fceux 2.1.6. it has seemed stable in initial testing, but expect bugs as this is new.
|
|
|
|
2. Installation
|
|
Fceux is installed with the scons utility. To compile, run:
|
|
|
|
scons
|
|
|
|
After a sucessful compilation, the fceux binary will be generated to
|
|
./src/fceux . You can install fceux to your system with the following command:
|
|
|
|
scons install
|
|
|
|
You can optionally define a prefix:
|
|
|
|
scons --prefix=/usr/local install
|
|
|
|
You can choose to install the lua scripts (located in output/luaScripts) to a directory of your choosing:
|
|
|
|
cp -R output/luaScripts /usr/local/some/directory/that/i/will/find/later
|
|
|
|
3. Compile-time options
|
|
You can enable and disable certain features of fceux at build time.
|
|
To edit these options, edit the "BoolOptions" following the "opts.AddVariables" method
|
|
at the head of the "SConstruct" file in this source directory. The
|
|
default options will be fine for most users, but power users may want to
|
|
tweak some of these options.
|
|
|
|
4. GUI
|
|
You can enable the GTK GUI by setting GTK to 1 in the SConstruct build file.
|
|
Gfceux is deprecatiated in favor of the new GTK GUI. You can disable it at
|
|
run-time by passing the --nogui option, or disable it build time by setting
|
|
GTK to 0 in the SConstruct file. If you prefer GTK3 to GTK2, you can set the
|
|
GTK3 BoolVariable to 1 in the SConstruct.
|
|
5. LUA Scripting
|
|
FCEUX comes equipped with a LUA scripting engine that opens up endless in-game scripting capabilities. You can enable LUA at build time by enabling the "LUA" BoolVariable in the SConstruct file.
|
|
|
|
The LUA scripts that are shipped with fceux are located in:
|
|
|
|
$source_directory/output/luaScripts
|
|
|
|
You should be able to run most of the scripts in this directory out of the box. However, some of the the lua scripts require functionality from the "auxlib.lua" library. This file can be found in "./bin/auxlib.lua" or "./src/auxlib.lua". You will need to place this file in the LUA library search path if a script bombs out looking for auxlib.lua, it will let you know where it looking for it (/usr/local/lib/lua/5.1/ on my particular system). You can simply copy the auxlib to a preferred location to utilize the functions in the auxiliary lua library.
|
|
|
|
In addition, some of the lua scripts require functionality from the "iup" GUI library. You can obtain binaries and source for "iup" upstream (http://www.tecgraf.puc-rio.br/iup/), but I would recommend obtaining packages from your Linux distribution if you are able, as it can be difficult to compile or get the binaries working correctly on a given system.
|
|
|
|
You will need to add the location that the libiup*.so files to the LUA_CPATH. This can be done with the following command (please note that the location where iup is installed with vary based on how you installed iup):
|
|
|
|
export LUA_CPATH="/path/to/iup/lib/lib?51.so;"
|
|
|
|
On my Arch Linux system, it turned out to be the following:
|
|
|
|
export LUA_CPATH="/usr/local/lib/lua/5.1/lib?51.so;"
|
|
|
|
Finally, if any scripts complaints about "attempt to index global 'iup' (a nil value)", this means that "iup" needs to be explicitly loaded into the script. You can add the following line to the head of script to manually load "iup":
|
|
|
|
require("iuplua")
|
|
|
|
The "iup" libraries are admittedly time-consuming, difficult, and an overall pain-in-the-ass to install and configure on a Linux system. However, if you follow the above steps you should be able to achieve iup functionality (GUI elements) in fceux lua scripts if you so desire.

6. FAQ
|
|
|
|
Q. I'm having issues with my sound!
|
|
A. First of all, for the best sound quality be sure you are using SDL 1.2.14 or later. Versions 1.2.13 and earlier are known to have problems with fceux! Next, try different SDL audio drivers to see if this makes any difference. You can do this by using this command before running fceux:
|
|
|
|
export SDL_AUDIODRIVER=driver
|
|
|
|
where driver is either:
|
|
'pulse' for pulseaudio
|
|
'alsa' for ALSA
|
|
'dsp' for OSS
|
|
'esd' for ESD
|
|
|
|
There are sound options that you can tweak at runtime through command line switches:
|
|
|
|
-soundq x internal sound quality hack value (0 off)
|
|
-soundrate x sound rate (sane values: 28000 48000
|
|
-soundbuffersize x (in ms) sane values (30, 50, 100, 120)
|
|
|
|
* Running fceux through esddsp is known to fix some audio issues with pulseaudio on some older Ubuntu versions.
