HOWTO: Install (G)FCEUX 2.0 NES emulator

[rifter]

I'm on a Debian Lenny system. And I'm not getting sound. I used the first post's instructions in this thread. Maybe things have changed?

Either way, I'd really like sound.
Yes, sound on my box works (not with the FCEU, though).
I believe I'm using an ALSA setup at the moment.

00:10.1 Audio device: nVidia Corporation MCP51 High Definition Audio (rev a2)

What kind of sound mixer are you using? (pulseaudio, esd, etc)?
If you don't know chances are the man pages will give a hint (did for me) try
apropos esd
apropos pulseaudio

and see what you get. You can force an application to use your mixer in those two cases with the

esddsp

and

padsp

commands, respectively. Just put either one before the program you are launching like:

esddsp gfceux

note that if you have pulseaudio it has a wrapper for esd. For some reason on my system even though I have pulseaudio some programs will not work with the padsp command but will with the esddsp command (which is a wrapper to pulseaudio that takes esd style input). Your mileage may vary.

I just checked out version 1753. Sound doesn't work very well. Tried with padsp wrapper as well. My system doesn't have pulseaudio problems in general.

Also, can't get any of the OpenGL scaling modes to work. It's probably related to the OpenGL bug 2740043 on Sourceforge. If I enable any of the scaling modes I just get a seg fault like this:

I was wondering , how can I remove fceux , if installed with the method mentioned in the first post?

Has anyone here ever gotten fceu to work with an XBox controller? I have almost gotten it, but just can't quite get there. I have everything working except for the d-pad, which fceu just won't recognize. It's weird because SuperTux will recognize it, and fceu actually works with the joystick. It's just that playing NES games with a joystick is awkward.

If anyone can offer any advice at all, I'd appreciate it.

Like the dev said earlier, it seems the input configuration in FCEUX isn't up to par yet.

In the meantime you should use a joystick->keyboard mapper to make your joystick create keypresses instead of button presses. Personally I use QJoyPad which has profiles, can map axises as well as buttons, and has a very user friendly dialog to set everything up. You can even set up one of your analog sticks to act as a mouse, if you like!

Other alternatives that I've heard of but not tried include xjoypad and rejoystick (which I've heard good things about).

Unfortunately I don't think any of them come with a ubuntu package at this time. QJoypad wasn't difficult to compile. All I did was download the source and make sure that I had the needed libraries before running "./configure" then "make".

If configure complains about missing libraries, try running the following apt-get:

sudo apt-get install build-essential libqt4-dev qt4-qmake libqtgui4 libqtcore4 libxtst6 libxtst-dev

That should get more or less everything you need to compile programs, including this one specifically.

Thanks for that post. I'll give it a try. I tried jkeys once, but it didn't seem to map axis, just buttons, and for some reason the d-pad on the Xbox controller is an axis, not 4 buttons.

I'll try out some of those and post here about how it worked out.

Thanks,
Derrick

I followed the method mostly but I had already downloaded the current version so I just followed the method from my download folder. If I'm not mistaken I'm supposed to just move the folder elsewhere right? If so what folder would you suggest (Single User-Ubuntu 9.1)

QJoyPad works great. I'm running GNOME and so I tried the others first (since QJoyPad uses QT) but they weren't anywhere near as good as QJoyPad. I tried Jojsticken, which is the newer rewrite of Rejoystick, but it just didn't recognise the d-pad. Then I tried xjoypad, but it just wasn't very user friendly to set up. QJoyPad ended up working great, and it was easy to compile and install.

OK Going to try this ? what about system requirement ?

I didn't install FCEUX, but I installed the older version, FCEU, that is in the repositories. I have a little, underpowered netbook, and it works fine, so I'd say the system requirements are pretty low.

The only problem I encountered was that the graphics were a little choppy on my cheap integrated video card. Disabling OpenGL fixed that though. I think the option I had to specify was -opengl 0. After that, and after using QJoyPad to set up the controller, it works great for me.
