Add NeoGeo

[williambout]

You should add NeoGeo emulator : http://blog.sheasilverman.com/2012/06/neo-geo-emulation-on-the-raspberry-pi/

Are you running the NeoGeo emulator successfully?

[williambout]

Yep. Here is a video I've made http://www.youtube.com/watch?v=oeUTnLhOhww

Ok, that IS working fine. I will add it with the next commit ;-)

Great. You'll find all you need here : http://blog.sheasilverman.com/raspberry-pi-emulation/

I just tried out the pre-compiled binaries and the tutorial from the Sheas blog, but they are not working. I will try to compile GnGeo on my own and add the script for that to the RetroPie script.

[elpendor]

Works fine here. What's the error?

[petrockblog]

It does not generate the .gngeo directory when calling it with gngeo -i ...
Hmmm, seems that I need to spend some more time. Are you using the latest firmware with all upgrades?

[elpendor]

Yeah.

Now that I think about it, it happened the same thing to me the first time. Hmm, I can't remember what I did.

Did you run it using sudo? How about running it with no extra parameters?

[petrockblog]

I tried it both, as admin and as user pi. But I have to admit that I did not spent too much time trying. Job-related I am away for a week now. I can have another look at it when I come back.

[elpendor]

I'd say just run ./gngeo. I think that's what I did when it didn't create it.

[williambout]

Oh and Playstation One Emulator looks pretty cool also, check it out : http://youtu.be/XDBWODvWSkY

[petrockblog]

With which command line parameters are you starting gngeo? Currently, I just got a black screen when I try to start, e.g., Metal Slug. Do I need to use a certain BIOS?

[petrockblog]

Ok, following the instructions from "blc" (http://www.raspberrypi.org/phpBB3/viewtopic.php?p=148248#p148248) I managed to compile gngeo and to start gngeo with Metal Slug 1. However, I can only see the first seconds of the splash video and get a segmentation fault afterwards. I included the installation script for gngeo in the recent commit - if someone has an idea how to solve this problem the gngeo emulator would be a nice addition to the RetroPie collection.

[petrockblog]

@elpendor: I really would like to close this issue with gngeo. As written above I managed to compile it and make it run for a few seconds.
Could you maybe answer me a few questions in the hope that these will lead me to a solution?

• From where did you download the sources of gngeo?
• Which version are you using?
• Did you use the Universe BIOS or something else?
• Where exactly did you put the BIOS? ToadKing wrote this: (http://www.raspberrypi.org/phpBB3/viewtopic.php?p=189697#p189697), but I only managed to make gngeo run by extracting the BIOS zip file, putting it some place and pointing gngeo to it via command line parameters.
• With which ROM did you test your installation?

Thanks a lot!

[elpendor]

• I got the compiled binaries from the blog mentioned a few posts earlier (http://sheasilverman.com/rpi/gneogeo.zip)
• Check first answer.
• The BIOS file I used does contain the Universe BIOS (several versions) and some other.
• Same folder as the ROMS. File is called neogeo.zip, did not extract it.
• Metal Slug 3 and 5

[petrockblog]

Thanks for that!

[petrockblog]

Are these steps working for someone?

hi petrock, did you resouled the segmentation fault issue? I have tried some roms like street hoop or kabuki klash but all i get is choopy gfx glitches, sound is working well.

Any suggestion?

[petrockblog]

I had it successfully running ONCE. Then I tested the RetroPie script with another installation and I got these segmentation faults again. I used Metal Slug for testing ...

[aguirrech]

Have you constasted gfx issues, like background missing or sprites flickering in some games, Street Hoop, Kabuki Klash, neodrift, and other ones? Otherwise sound is working well. I can't get neogeo roms listed in emulation station after installing it by your retropie_setup source mode. Any ideas?

[aguirrech]

may be with an older gngeo version?

[petrockblog]

I run Metal Slug without any graphic glitches and with perfect sound (even via analog audio out).
Could you provide the link to the sources that you used for compiling GnGeo? Also, it would help me a lot if you could point me to

• the content of your ~/.gngeo/gngeorc
• the command line that you use for starting a game
• the BIOS version that you are using,

[petrockblog]

In order to have ES showing NeoGeo roms, you need to add some lines to ~/.emulationstation/es_systems.cfg:

NAME=NeoGeo
PATH=$rootdir/roms/neogeo
EXTENSION=.zip .ZIP
COMMAND=hereTheCommandToStartA %ROM%
PLATFORMID=24

Hi, i compiled myslef lastest gngeo version 0.7 with this tutorial.

Bios mode is set to Arcade it is the only that i can'get running. Other bios modes, Home and Unibios, boots but nothing is displayed. What bios version have you installed?

[petrockblog]

Thanks for that!

I just put the whole code from above into a code environment.

I did not play around with the system type settings yet - good point!

[ReliCWeb]

I'll have to try the above config, but I did a fresh source compile of gngeo using RetroPie-Setup and I can't seem to get it working quite right. I've copied my bios and roms to their locations referred to by the es_systems.cfg COMMAND. I can get the gamelist to appear in ES no problem, and when I select a game it launches the bios (NeoGeo Max Spec screen, at least I think that's the bios) but immediately crashes when it tries to load the game.

If I write a custom launcher script it works great. It launches from ES with no issues. The script is similar to below (paths might be off, don't have Pi handy):

#!/bin/bash
/home/pi/RetroPie/emulators/gngeo-0.7/src/gngeo mslug
exit 0

Note how it's just passing in 'mslug'. GnGeo has games setup with shortcodes so you can just pass the shortcode to launch the game. 'gngeo -l' will list the games it's setup with I believe. It's odd that if I pass the whole rom path it doesn't work. I don't have everything handy in front of me, but I recall it appending an extra '.zip' to the end, resulting in it not being able to find the file. Is that a GnGeo issue?

[petrockblog]

I finally managed to come up with a reproducible way for installing GnGeo. There was an error in setting up gngeorc in the home directory of the current user.
