Great! Thank goodness there wasn’t anything wrong with the image.
As to why you couldn’t see them to begin with, it could have been a variety of reasons. If using a command line (cp), it could have been a file transfer in progress without a progress bar, prematurely interrupted. Likewise with a drag and drop launcher.
Some file transfer programs initially get you to give input to move your selected files into place, then hit a “transfer” or “execute” button. This can be a good safe guard against accidentally dragging and dropping files while scrolling. This could have been forgotten.
At the end of the day, it’s probably best to just follow instructions perfectly, without taking any shortcuts. Pretty much all tutorials get you to transfer files via SSH. Sure, it’s faster to do a direct file transfer with HUGE batches of files, but hey! If it doesn’t work, try the recommended method before panicking.
On a side note, do you actually use your game shell as a music device on a daily basis? Like, seriously? I just find that the sound quality on the board is sub par. The only thing I use it for is streaming music/podcasts via air play while playing existing games. If only you could stream music from your game shell to airplay/sonos devices! Sure you can use bluetooth, but honestly, who has a 24/7 always on bluetooth speaker system? If you do, Great!
I have gotten MPD to play while playing existing games, but until I sort out some hooks to control MPD with shortcuts, similar to the volume shortcuts, it’s just too finicky and annoying. If you’ve got a machine SSHing into the GameShell, you might as well just use that machine to play music. I just prefer using my phone for music, like PSO, Final Fantasy etc.
One thing to consider using the MPD for is perusing the dumped music files from ROM images. Eg, SNES SPC files. The diminutive sound that comes from the GameShell is almost perfectly suited to this kind of music; just like the low res interpolated screen.
