2 Pi4 questions

mitu

When I enter mount -a I get an error

Use sudo mount -a and then just run mount to see the mounted filesystems.

How do I download?

Enable SSH on the Pi and then use WinSCP to access the full file system from your PC, just like you do with the file manager.

I see the drive. Not sure what it all means.
`/dev/sda2 on edia/usb0 type fuseblk (rw,nodev,noexe,noatime,sync,suer_id=0,goup_id=0,defaul_permissions,allow_other,blksize-4096)
log can be found here

From the log file, it looks like none of the ROMs folders are found. Your drive is not mounted under /home/pi/RetroPie/, but under /media/usb0, so it's normal that Emulationstation doesn't find them.
Did you disable the usbmount service before adding your drive to /etc/fstab ? Do you see the ROM folders under /home/pi/RetroPie/roms ?

bc320

Yes, usbmountservice is disabled.
no, /home/pi/RetroPie folder is empty. I believe the contents of this folder was moved to the USB drive when I did
sudo mv -v /home/pi/RetroPie/* /media/usb0/

I looked at the HDD and noticed that there are 4 folders in the root directory. One I created called retropie-mount and then the three copied over from the Pi. Should those 3 be in the retropie-mount folder? Could that folder be part of the issue? This is from when I tried to do the automatic method setting the usb hdd to store the roms.

bc320

think I got it
changed the ect/fstab from what the directions said to
UUID=0A8C7E228C7E0889 /home/pi/RetroPie ntfs-3g nofail,user,uid=pi,gid=pi,umask=0000 0 2

Not sure the difference but found this on a redit thread. now to try read/write.

Another question now that I have this set up (I hope)
To add roms can I do the following?

Power off Pi4 using the ES system shut down
Turn power off at switch
remove HDD and attach to PC
load other roms, bios, etc
plug hdd back in
power system on

Or is there another method I should be using? I like this for large files compared to Samba or WinSCP

@bc320 Sure, you can use the disk on your PC, as long as it's properly un-mounted from the Pi (shutdown will do that).

@bc320 In addition to @mitu's advice, you should also safely remove the drive from your PC to avoid data loss and keep the NTFS in a consistant state (Linux won't mount it if its inconsistant).

That said, on a current Windows 10, the above may not be necessary anymore, but you should check if that option is enabled on your system.

Ran into a bit of an issue last night. After I got the USB drive working I tried all the systems I have on it. NES, SNES, GEN, and Atari all seem to work well. N64 doesn't. It is slow everything is slow and audio sucks. Could it be because it is coming off the USB or is it the Pi4? I will admit I failed to try it before I set up the USB hdd.

Clyde

N64 roms are only 5-30 MB each, which can be loaded in a blaze even from a slow usb device. I also suspect that RetroArch loads a rom completely and not only parts of it, so it should not matter after the game starts.

The N64 doesn't run well on a Pi 3 and the support of the Pi 4 is preliminary at best. So, I think that RetroArch and/or the underlying operating system is to blame for your problems, especially since older systems do run without difficulty.

If I were you, I would wait until the Pi 4 is properly supported by RetroPie. With NES, SNES, GEN, and Atari you have many systems to pass the time, after all. ;)

@Clyde
That's what I was thinking. N64 seems to be a bugger on everything. Just making sure I wasn't missing something obvious.

Sort of hijacking this thread but seemed appropriate as it was a question about the raspberry pi 4 and thiers already enough threads asking questions .mostly out of curiosity will the 1gb 2gb and 4gb versions require separate builds or will it end up being an all encompassing image

@gorgar19 RAM size won't make a difference.

bc320

I have no idea but have always subscribed to the idea that you get the most you can afford. it can't hurt.

Clyde

@bc320 I'm with you on this. With such a versatile machine like the Pi (any model) you don't know what you'll be using it some years into the future. Furthermore, Retropie runs on Linux which uses free memory to buffer I/O operations to speed up file access etc. You can see the memory allocation with the command free -h.
