My guess is it’s just super slow. Some of my roms are on a USB HDD attached to my pi. That HDD is formatted in such a way that windows can’t see it. Since all my PCs are windows machines, I have to transfer roms to the HDD via SSH to the pi. The USB transfer speed is snail-like. lol
I’ve spent many hours on google looking for a way to speed it up, but nothing has worked.
^^ my other hobby
It’s hit or miss for me. It loaded ~1,110 roms in less then an hour, but that is only 50% of the library on my USB. Now it has spent +14 hours and it has transferred less than 10 roms. I’ve rebooted and it doesn’t help. I agree; it gets hung for some reason. the slow rom transfer isn’t a function of it moving bigger files, and I still have plenty of free space on the sd card… I think it is a bug. I might report the issue on the GetHub page if others have noticed this too. Godspeed and happy gaming.
It is nothing to do with retropie itself but perhaps an issue with the underlying OS (Raspbian). Might be worth rolling back the RPI kernel to see if it is a kernel related problem (and things like trying the old sdcard driver – dtoverlay=mmc to /boot/config.txt)
It worked fine with just a small handful of tiny NES/SNES/Genesis roms, but when I tried large PSX isos it failed every time. The USB stick would blink for less than a minute or so and then transfer would stop.
I disabled the USB rom service using the setup script and just manually copied them over from the USB stick using terminal commands and the transfer speed was normal.
