How do you really add/remove emulators from retropie?

[fr0zen]

Hello there Pi-Peeps! First of all, I would like to thank everyone here for contributing and answering questions for noobs like me.. *thumbs up!*

I know little to nothing about linux commands (more like nothing, lol) so please bear with me..

My question is, how do you add/remove/replace applications/emulators from retropie?

I have found some useful topics here but they are only useful at the start; I mean when people say “install them from the setup script within retropie_setup.sh”, that part is alright because I can get to it. The fun part starts next though, whenever the instructions tell me to go to a certain directory that does not exist. For example: ‘/home/pi/RetroPie/emulators’ the ’emulators’ folder does not exist anywhere..

If its hidden, how do I get to it?

Next problem is emulator specific.. the default SNES emulator is running fine but the sound is horrible.. Again, found some topics about overclocking and switching to a different emulator. Overclocking part is done, but I cant do the ‘switch emulator’ part…

This might be similar to other posts and I apologize if so.. I can follow instructions quite alright but if the folders/files do not exist, I simply cant.. I might be looking at the wrong place or doing something wrong, I don’t know.. Thanks in advanced!

Overclocking should fix the original emulator problems, it may not be necessary to switch emulators.

To switch you edit es_systems.cfg but I’m not sure of the dir. If you’re lazy you can

find / -print|grep es_systems.cfg

or maybe updatedb && locate es_systems.cfg if the fs supports it

[zsprawl]

The file is located at:

~/.emulationstation/es_systems.cfg

or

/etc/emulationstation/es_systems.cfg

Check out my other post on this forum for step-by-step setup directions for version 2.2.

Thank a bunch guys! will try it out when I get home from work and update this thread! :)

I’m interested to see if pisnes works for you. I haven’t had any luck yet in the new or old version.

[iam8up]

Does the one in ~ superceed everything the one in /etc/ ?

Yes I believe so. You may just wanna delete one or the other. I personally use the one in /etc/emulationstation/ and the one in ~/.emulationstation is non-existent.

I’ve heard of some people downloading the copy off the Internet and overwriting the copy in /opt/retropie/emulators/pisnes. This used to be needed in 1.X for me, at least some versions. However pisnes works great in 2.X for me.

Here are the steps:

cd /opt/retropie/emulators/pisnes
cp snes9x.cfg snes9x.cfg.bak
wget http://pisnes.googlecode.com/git/pisnes.zip
unzip pisnes.zip

[fr0zen]

Ok, so I managed to get to es_systems.cfg and found out that you really cant straight away switch to a folder within a folder.. I don’t know but cd /folder1/folder2/targetfolder does not work for me.. I had to cd /folder1 then cd /folder2 etc…

Anyway, I edited es_systems.cfg by using the “sudo nano” command (thanks google) and did these lines exactly as you see here (after installing pisnes though the source script in retropie_setup.sh):

<system>
<fullname>Super Nintendo</fullname>
<name>snes</name>
<path>~/RetroPie/roms/snes</path>
<extension>.smc .sfc .fig .swc .SMC .SFC .FIG .SWC</extension>
<command>/opt/retropie/emulators/pisnes/snes9x %ROM%</command>
<platform>snes</platform>
<theme>snes</theme>
</system>

I started emulationstation after a reboot and there seems to be no change at all with the performance of snes.. Am I supposed to see PISNES anywhere?? or I guess the question is, how do I know that I have changed emulators already?

I just wanted to understand this.. The steps you gave are actually commands that one should input in the command prompt prompt right (f4 while in the emulationstation)? I was just asking because there’s an ‘unzip’ entry there.. Sorry.. so noob of me..

This is what I did and it improved sound issues dramatically.

Yes, everything I tend to ask people to do is on the linux command prompt. Either SSH into the raspberrypi or, as you mention, exit out of emulation station and type said commands.

Yeah, go Turbo and it works fantastic. Just grab some heat sinks off Amazon first.

[smatticus]

I haven’t gone turbo yet. Need to get those heatsinks still. But I’m doing a modified 1ghz overclock that seriously fixes plenty of performance issues. I’ll need to tinker with pisnes more. I will say that certain games look MUCH sharper in pisnes with zsprawls settings, but super metroid runs poorly. And right now getting that game running PERFECT is my white whale.

I just installed a fresh copy of the retropie 2.2 image. Expanded the disk space, shared mem set to 384, and went turbo. Never made any changes with es_systems.cfg then launched emulationstation. The problem with the ‘crackling’ sound is still there… Later, I’m going to again try switching to a different emulator..

[fr0zen]

sound problem is still there.. If anyone has snes working fine on an hdmi without the annoying cracking sound, please post your settings.. #frustrated

[InsecureSpike]

a couple of posts back I posted my SNES retroarch.cfg file, it features a Mario Allstars work around!

Don’t know if you are still having this problem @fr0zen, but in the snes9x.cfg file make sure that AutoFrameskip=1 . When I set that to 0 the audio was broken, but when i changed it back to 1 the audio was fine.

Do you have linux on any other pc?If so I use the drag and drop method using my linux machine its so much easier than using the terminal.I find the commands you people post then look for the folders on the card in my linux mint machine.You can edit remove delete add whatever.Take your sd card out of the pi and put it in the linux pc and go from there.I don’t know why any of you use the terminal.I bought my pi2 a month ago and only have used the terminal to set up the pi.After that I use my linux machine for adding roms and for adjusting arch.No terminal needed.Not even for the controllers.All the config files can be found with out the terminal.
