Most likely the USB stick is not 'mounted' (therefore inaccessible) when the splashscreen starts, so the video cannot be read and the splashscreen fails. Copying it to /opt/retropi.. will copy the splashscreen on the SD card, which is immediately available on boot.

Couple comments: When using a USB drive through the auto-move capability of RetroPie, the entire RetroPie folder is read from the USB drive; i.e. it "replaces" the RetroPie folder on the boot sdcard. The videos you place in the USB folder of RetroPie/splashscreen (which becomes "/home/pi/RetroPie/splashscreen") can be read by the Splashscreen functionality, and even randomized - with some caveats I'll note below. You can always move the video splash screens to the sdcard folder of "opt/retropie/supplementary/splashscreen" and use them from there as well. You can do that in a number of ways: from the command line (F4) then copy or move the files from the "/home/pi/RetroPie/splashscreen" folder to the "opt/retropie/supplementary/splashscreen" or do the same through SSH or through the built-in File Manager application from the RetroPie settings subfolder. Hint: sudo cp "/home/pi/RetroPie/splashscreen/whatever your video.mp4" "/opt/retropie/supplementary/splashscreen/whatever your video.mp4" wil copy the file. Replace cp with mv if you want to move the file. You must do this as SU (sudo) because the opt folder allows only root read/write access Caveat 1 for randomizing: Best to append the video files to the splashscreen list, and then randomize off that list Caveat 2 for randomizing: Frequently the very first file name on the splashscreen list will be multiple files all in one long line. Recommend deleting that entire line and manually typing in the first line. Editing the splashscreen list is fairly easy. A. In the Splashscreen settings, go to "Append splashscreen to list" B. Choose Own/Extra splashscreens (if your files are in the home/pi/RetroPie/splashscreen folder) or RetroPie splashscreens (if you moved them to the opt/retropie/supplementary/splashscreen folder) C. Select the line you want to append (add to) the list and hit OK. D. Hit Ok again to confirm the appended line E. Repeat B-E for all the files you want to add to the list. Again - I recommend after you're done appending the files that you go back to "Manually edit splashscreen list" and make sure that first line has ONLY the one file on it. I also again recommend you manually type that one in. It might be easier to do this after you've appended a few files because you can just copy one of the lines you appended as the first line, and then delete the original (now duplicated line.) Once your splashscreen list has all the videos you want in it, one vide per line, go back to Disable splashscreen randomizer and enable it (or disable and then re-enable it.) You'll want to select the "Randomize /etc/splashscreen.list" selection.

@herb_fargus Possibly. But the display settings are correct and the aspect ratio of the splash video matches the vertical screen exactly.

@pokeengineer Thanks Man!

This is pretty funny and weird at the same time, but basically on the RetroPie-Extra splash screens, something that I noticed was that someone already created a LEGO Pi splashscreen. This is completely unrelated, but I noticed it very easily.

@mitu Presumably Ruby's referring to the video links (which I decided to upload to either mixtape.moe or pomf.cat at the time). Of course, since neither of those sites operate anymore, I decided to reupload it to something that's (hopefully) more reliable. And just for the sake of prosperity, here's the video from the original post and the first update (complete with the never-before-seen original file names!).

can't wait to see the finished product, Looks beautiful

@allanbuzzy Unfortunately, no; the sound effects were manually edited in post since ES doesn't support custom sounds when scrolling on systems. :(

Nice idea. "Parody" splash screen are fun and look cool, a you're right, RetroPie should have it's own unique flavor. Thanks for sharing!

@Yourdrunkendad nice :)

@Dr-Ocelot I dig these a lot, very nice work!

Me too, I like the idea. Shutdown splashscreen sounds great.

@jdrassa This method seems to work great if the UI modes are not in use but if it's set into Kiosk mode the es_settings.cfg reverts to an unmodified state after reboot. Does enabling the Kiosk mode overwrite the es_settings.cfg file? If so can I modify the Kiosk mode to include the splash screen setting?

@Freakadude Thanks for the feedback but I didn't make the shorter version of the song. I got the shorter version from some youtuber but the visuals I did make so I can't really do anything about the song transition. Sorry.

@mikeh1982 you can also use sites that you out in the YouTube URL and it will download a mp4

Cool idea. Love all the classic Lucasfilm/Lucasarts adventure games and for me Maniac Mansion was the first one that got me into adventure gaming so this is an instalike from me :)

@mikeh1982 Transferring the ROMs via USB is done automatically so there is no need to look at the directories, you don't need to manually move anything. If you use samba share over the network then the 4 directories are automatically shared to allow you to edit, transfer, delete, manage etc... Just as a tip, you can add extra folders / directories to be shared over the network. If you go to /etc/samba and open smb.conf you can add entries, eg [home] comment = home path = "/home/pi" writeable = yes guest ok = yes create mask = 0644 directory mask = 0755 force user = pi Or add any other path you want to access...
