Whenever I plug into the USB 3.0 it just writes non stop. I don't know what the problem is. Could it be the enclosure??? Is the lack of USB speed going to make a noticeable difference in gaming? Any ideas why this could be happening?
Try looking at the system's messages when you plug in the drive, by running dmesg -w (CTRL+C to interrupt) on the console and see if any errors are displayed.
Make sure you've updated your system (sudo apt update && sudo full-upgrade) to get the latest stable USB firmware and kernel/firmware release.
There's a sticky topic in the RPI forums here for troubleshooting problematic USB3 SSDs, you might want to take a look and see if your enclosure's USB SSD adapter could be one of the models reported with issues.
@koogelpotato Are the files listed when you ssh/SFTP to the snes rom directory on the pi? If so, check if they are all the accepted file extensions. If you've confirmed the files are indeed on the USB drive, you may want to check your freespace on the pi with df -h to see if you are out of space on the SD card.
@pandamkii You don't unzip MAME roms, this is the way they're distributed they'll not work otherwise. If you're considering adding MAME to your setup and you're a beginner, then please read the Quick Start and the topics linked on that page. It will answer most of your questions and will help you understand how MAME rom(set)s work.
Which system? When you post about a problem try to be specific. I think its the MAME games who don't work? You did update the emulator which requires a newer romset. You need to rebuild the romset to the required version for the emulator and it will work.
Well, the mistake was mine altogether!
As I said: I'm new to this. What I didn't know was, that I can't just create new folders in the ROM directory manually and than move ROMs into it. It needs the emulators to be installed FIRST. By doing that the folders will pop up automaticly.
Now everything works just fine.
Thanks for trying to help.
Mame is a beast not to be messed with. Mame will hurt you if you don't look after it and treat it well. It can affect you psychologically. Do a quick search on here and you'll see the pain that others have suffered at the hands of this behemoth. They all tried to tame it without following guidance.
