Quick and easy guide for adding music to Emulatonstation on RetroPie. Noob friendly!

Naprosnia

@cyperghost Thanks for your feedback. Im rewriting all the code and applying your fade method (works like a charm, thanks), and add new settings (enable / disable fade; enable / disable "BGM stop" on emulator start [some people want their music playing while they play games] ). Now im using a settings file to save user choices, and reduce the number of files used, for a clear environment.
Im trying to finish this today.

If anyone has more ideas of new options that can be added please say.

Hi,
I install your script, but I don't have the Background Music Settings option on RetroPie settings menu.
Otherwise, how uninstalling your script.

My config:
pi3B
Retropie 4.4.7
Emulationstation 2.8.1rp

Naprosnia

Hello @WarC0zes, when RetroPie and EmulationStation loads, press F4 to access command line, then,
execute this code:

sudo ls RetroPie/retropiemenu/

next, a list of files will appear, check if there is one called "Background Music Settings.sh"
- if yes, execute the following code to open Emulation Station again emulationstation press Enter
  - next, inside Emulation Station press the button ("start") to access Main Menu, go to "OTHER SETTINGS" and check if "PARSE GAMELISTS ONLY" is set to ON, if it is, please put it to OFF and restart your system, and check if the Background Music Settings appear.
- If no, you can execute the following command on command line to disable BGM touch /home/pi/.bgmstop

Please leave some feedback.

@Naprosnia

You have solved my problem, I had the option "PARSE GAMELISTS ONLY" set to ON.
I put it to OFF and restart my system and I have the option now.
Thanks

sorry for my english.

@cyperghost Thanks for your feedback. Im rewriting all the code and applying your fade method (works like a charm, thanks),

You're welcome, please add the link to the original code into your modification if you make heavy use of these scripts.

new settings (enable / disable fade; enable / disable "BGM stop" on emulator start [some people want their music playing while they play games] )

I would avoid such settings. Therefore we have the User Menu from runcommand. There you can select to enable BGM again and with exit 2 you finsh runcommand and load your ROM. I think this makes more sense.

Read here about the Runcommand menu

sudo ls RetroPie/retropiemenu/

There is really no need to execute scripts with root level. Your scripts need heavy code review to avoid right privilege errors.

Then make the code more lightweight. If there is a action you are doing again and again then use functions and loops.
A good example the the dowload of the config files -- Use an array with a loop
Or the download of the example music use the expression {1..7} to count from 1 till 7

Hello @cyperghost , has I said, I'm rewriting everything from scratch. I'm trying to follow some of your tip, such as reduce sudo a lot.
I will certainly put your name and git link in the description of the scripts.

cyperghost

@Naprosnia You are welcome
I will comment on your github account.

EDIT: Added my first comment as "issue"

cyperghost

@Naprosnia Added annother "Issue" for code cleanup ;) the second regards the volume control. This is a real interesting feature ;)
As long as your coding works for you it is okay. But look if you might change a path or a call you've to edit it 10x in your scripting. With my solution it's just one edit.
Issue #2
Issue #1

Naprosnia

New version released, now with fade effect , and possibility of listen your musics while playing games.
Special thanks to @cyperghost for the fade script!

@Naprosnia A nice set of scripts that will surly help less advanced users to quick install a mp3 BGM player. There is still room for improvements to the code but this looks much better now. You are heavily mixing shell and bash expressions together ... try to use one style.

Btw: for variables it is not needed to seperate them
like BGM=$PATH1"/more/pathes/"$PATH2
just use BGM="$PATH1/more/pathes/$PATH2" so you will avoid globbing even if it's very uncommon in every other programming language I know but you will appreciate this behaviour.

Thank you for this nice tutorial. Have followed all instructions and i will be glad now playing my favourite music in background.

WarC0zes

@Naprosnia Nice update, I love it.

WarC0zes

@Naprosnia After testing, when I start a game the music is cut and when I leave the game the music doesn't come back.

My setting in emulationstation / Sound setting:
Audio card = Default
Audio device = PCM
Enable navigation sounds = On
Enable video audio = On
Omx player audio device = Both

Brigane

@WarC0zes Are you using any kind of USB Sound card?

I cannot elaborate what my problem is at the moment because I'm in school, but I have a similar problem with my setup and I think it has to do with the fact that I'm using a USB Sound card.

WarC0zes

@Brigane No, I don't use a USB sound card. I use that of the pi.

@WarC0zes hello, i did a fresh installation on my system to check if it throw me the same problem, but no, it work normally.

- First, i need you to install RetroPie BGM Player again, you can install it over the current installation (dont need to uninstall).
[ Q. Why install again? A. Because, i have updated some code, and it could correct your problem. ]
-- And check if you got the same problem.

--- If yes:
---- I need to know if this occurs with fade effect, without fade effect or both.
---- I need you to check configs/all/ folder and check if you got this file-> runcommand-onend.sh
----- if yes, send me the code you find inside [if any] (you can open this file with any text editor).

--- If no:
---- Nice.

WarC0zes

@Naprosnia I install again, but same problem with fade effect or without fade effect.
My file runcommand-onend.sh is empty (0 Ko), no error code.

Naprosnia

@WarC0zes thank for your reply, i think i found the problem.
Install again, i updated the online version to correct this problem, but i need someone to test.

If the problem persists, uninstall with uninstall.sh file that you found on github (https://github.com/Naprosnia/RetroPie_BGM_Player)
and install again.

leave some feedback please.

WarC0zes

@Naprosnia
Install again = not works.
Uninstall with uninstall.sh and install again = Not works.

weird all works before your new update.
The only change I made since your update, is to steam link installed.

Naprosnia

@WarC0zes i found the problem. im writing a new fix. wait a sec. when done i tell you.
The problem is, sed cannot add new line to the beginning of a empty file.
