Never mind ..figured out doom 2 tnt and plutonia are all 32 levels in size and share the music file names.

Searching the forum I found this: https://retropie.org.uk/forum/topic/9133/quick-and-easy-guide-for-adding-music-to-emulatonstation-on-retropie-noob-friendly I personally use it at home and it's easy to setup.

@hooperre dont know if it works with ports, my retropie version is latest 4.5.1 latest setup-script and runs on linux Xubuntu 18.04LTS. btw, this is exact how it worked on my linux pc its exact what i did to get music in the menus, maybe do not forget to install mpg123 from synaptic package manager

for me a project being 'commercial' in nature doesn't necessitate it making a profit. besides, eventually someone sells the bus...

@Addison good form, very good form! That is truly stunning. I wish I had a CNC machine even more now. I really like the aesthetic of the 70s one too. Something about the knobs I think. I'll bet you could even play pong on that.

@Becciboo81 Well, RetroPie doesn't include any BGM music scripts - so you must have installed 2 scripts that play at once. Check the usual places for startup scripts: /etc/rc.local (you'll need to use sudo to edit this file). /opt/retropie/configs/all/autostart.sh and remove one of the BGM scripts.

@Protocultor Protocultor for President :D Thank you very much, it works. Now the only thing left I need to know is, can you change the deadzone amount of the left analog stick somewhere? I know you can change it in the option for ingame movements but it doesen't apply for the menu navigation and when I move up and down it often register a left or right movement and messing up my settings. UPDATE: Nevermind I found the settings in the config folder inside zdoom.ini

@PJ7 Not really possible at the moment, because the music is not part of Emulationstation. In the future, it might be possible by adding a script for the 'sleep' /'screensaver-start' event in Emulationstation that would stop the music.

@thestarglider My pleasure mate, I'm glad I could help :)

@mitu Ahh, makes sense.

Hey guys, yes I like that one too thanks @Stuart2773 but it sounds too much like the snes classic menu as I have the original on my Nintendo build already. I do like the one @Clyde posted but only like the start of it, I might have a play and crop and loop before it all starts going crazy haha.

@drewjbx Isn't the script linked in the topic mentioned in the first post - https://retropie.org.uk/forum/topic/347/background-music-continued-from-help-support ?

This is not currently supported in our emulation station.

@thelostsoul Just a quick answer to that (and apologies to everyone for the off-topic posts): Until Minecraft 1.14, getting cats was very difficult, because you'd have to befriend a wild ocelot with raw fish in one of the jungle biomes; this would turn them into regular house cats (one of MC's many strange laws of nature). But now, cats are a separate species that spawns naturally around procedurally generated villages. They are still shy, but way more trusting than the extremely timid ocelots.

@bleckman Look at how the Ports scripts are created - for instance Kodi - and you can replicate it to start the media player. Install Kodi, look at the kodi.sh script that it creates in the ports folder, and copy it and replace the Kodi start sequence with the command to start the program - from the author's instructions.

Search on YouTube, easy hax background music. I am using his work, very simple script he made for background music.
