Thats right. You only need to run the other options in the retropie script if you want to update the versions of the software, but they should work fine as is if you are using the ones in the 2.3 distribution.

There is a guide about setting your controller with Mame here:

[Floob]

RetroPie comes with mame4all, so you can use that ‘as is’ if you want

You can get the mame.cfg file here:
/opt/retropie/emulators/mame4all-pi

This is the scanlines option
display_effect=0

More info here:
https://code.google.com/p/mame4all-pi/

To remove the other emulators, just go into their directory here
/home/pi/RetroPie/roms

and delete any files in the directory – then it wont show in EmulationStation.

[Floob]

Try replacing your mame entry in that file with this:

    <system>
        <fullname>MAME</fullname>
        <name>mame</name>
        <path>~/RetroPie/roms/mame</path>
        <extension>.zip .ZIP</extension>
        <command>/opt/retropie/supplementary/runcommand/runcommand.sh 4 "/opt/retropie/emulators/mame4all-pi/mame %BASENAME%"</command>
        <platform>arcade</platform>
        <theme>mame</theme>
    </system>

That is the entry that relates to RetroPie 2.3 setup

and make sure your roms are in:
/home/pi/RetroPie/roms/mame

[Floob]

The mame rom path (for retropie 2.3) is /home/pi/RetroPie/roms/mame

That /home/pt/ directory is odd – it should be home/pi
That implies your user is wrong hence having permission issues.

Have you got a fairly clean install like this?

Actually – your path implies you are using an older version of RetroPie – I’d be tempted to run 2.3 instead?

[Floob]

It might be this value in the config.txt
overscan_scale=1

Check this post:

Using overscan in RetroPie to fit video to your display

[Floob]

Can you try some of the other numbers/settings to see if it comes out differently on the projector?

[Floob]

You could try changing the resolution here in es_systems file:
“COMMAND=/home/pi/RetroPie/supplementary/runcommand/runcommand.sh 1”

Try changing the 1 to a 4.

Details in this post

Using overscan in RetroPie to fit video to your display

[Floob]

You can find the retroarch.cfg files in
/opt/retropie/configs

This may also help

Please note the comment on that video about the directory – as the video is slightly out of date.

[Floob]

1. This should help

Using overscan in RetroPie to fit video to your display

2. Delete the txt (and any other) files you will see in those directories.

3. Try /etc/emulationstation/ directory

4. Should be ok – I’d be tempted to up the overclock, and check other snes roms.
Look at /boot/config.txt to confirm the overclock is set in there.

5. Neo Geo is fine for me:

Could be worth updating as well

sudo rpi-update
sudo reboot
sudo apt-get update && sudo apt-get upgrade -y

This has a tip at the top

Updated for 2.3: Step-by-Step Guide

[Floob]

You can add an exit emulator for MAME like this:

[Floob]

You can look at the es_systems.cfg file – usually in /etc/emulationstation

and change the runcommmand.sh value (between 1 and 8)
https://github.com/retropie/RetroPie-Setup/blob/master/supplementary/runcommand.sh

Otherwise it may be overscan

Video configuration

[Floob]

Have you set it up ok in Mame? With the tab button?
Check my mame video for that – once I did that, FBA worked fine as well for some reason.

[Floob]

Yes, as proxycell says, its most likely info from within a zip.
You can use ES built in scraper to get more details, or try something like this to populate the gamelist.xml files

[Floob]

A specific version seemed to help me:

This may also help you with save games

[Floob]

Here is a video showing the script in action

[Floob]

Here is some Neo Geo info:

[Floob]

Does this help with the Neo Geo side of things?

[Floob]

Thats its – check from 5 mins in on this video, just add the two lines into your controller file.
You would use “6” and “7” from your example.

[Floob]

But I cant see where you say you have run “sudo raspi-config” ?
This has the script all set up for you. If you run that and it gives an error let us know what the error is.
To be honest if you run that and it errors, I’d be tempted to re-install or check your sd card is known to be working.

http://elinux.org/RPi_SD_cards

[Floob]

Re-image the SD with the retropie .img then do this first:
http://elinux.org/RPi_raspi-config#expand_rootfs_-_Expand_root_partition_to_fill_SD_card

[Floob]

Dont forget to run “sudo raspi-config” first, as that has an option to expand your sd card for you.

[Floob]

Can you post your controller config here as a txt file?

Or have you tried exiting the game using the Escape key, as that should do it as well.

[Floob]

Have you tried keeping your controller config in the file created here:
/opt/retropie/emulators/RetroArch/configs

Then in your Retroarch.cfg file (in the /opt/retropie/configs/all directory) dont specify the buttons, just let it do it automatically with this

# Enable input auto-detection. Will attempt to autoconfigure
# joypads, Plug-and-Play style.
input_autodetect_enable = true

# Directory for joypad autoconfigs (PC).
# If a joypad is plugged in, that joypad will be autoconfigured if a config file
# corresponding to that joypad is present in joypad_autoconfig_dir.
# Input binds which are made explicit (input_playerN_*_btn/axis) will take priority over autoconfigs.
# Autoconfigs can be created with retroarch-joyconfig, manually, or with a frontend.
# Requires input_autodetect_enable to be enabled.
joypad_autoconfig_dir = /opt/retropie/emulators/RetroArch/configs/

Plus dont put any button configs in the retroarch system specific folders like
/opt/retropie/configs/megadrive

[Floob]

I just gave that a go and it seems to work fine – I created a game file as you do when starting for the first time, then when the game started I cleanly exited back to EmulationStation and the .srm appeared in the rom folder.

How are you exiting the game?

If its a permission issue check that your permissions allow user “pi” to write to the snes rom directory (unless you are saving your .srm files somewhere else)
See the attached pic.

If you need to update permissions, its probably easiest using a tool like Filezilla.

Have you tried this to get your controller working?

[Floob]

Video showing save states in RetroPie / RetroArch:

Video showing the internal / standard save feature:

[Floob]

I’ve deleted my ports so I cant check at the moment, but looking at the config, the ‘roms’ there are shell scripts themselves – so take a look in that directory and edit the file itself with nano.

/home/pi/RetroPie/roms/ports

[Floob]

In your /etc/emulationstation/es_systems.cfg file, are you running the roms with this entry, i.e. running it with RetroArch?

    <system>
        <fullname>Sega Mega Drive / Genesis</fullname>
        <name>megadrive</name>
        <path>~/RetroPie/roms/megadrive</path>
        <extension>.smd .SMD .bin .BIN .gen .GEN .md .MD .zip .ZIP</extension>
        <command>/opt/retropie/supplementary/runcommand/runcommand.sh 4 "/opt/retropie/emulators/RetroArch/installdir/bin/retroarch -L /$
        <!-- alternatively: <command>/opt/retropie/supplementary/runcommand/runcommand.sh 1 "/opt/retropie/emulators/dgen-sdl/installdir$
        <!-- alternatively: <command>export LD_LIBRARY_<path>"/opt/retropie/supplementary/dispmanx/SDL12-kms-dispmanx/build/.libs"; /opt$
        <platform>genesis,megadrive</platform>
        <theme>megadrive</theme>
    </system>

[Floob]

I think option 1 is the best default, although I would choose #2 to make sure I mean to escape the emulator.

[Floob]

If you are using retroarch, you set the hotkeys as above.

If you are talking about MAME, you can set it within the gui here:

[Floob]

If you need it, there is an overview of file locations here:

[Floob]

Maybe you could load a custom retroarch.cfg once you are in the game using the rgui with F1?
