How do i mount a .raw image?

Hello. I have installed Arch on a HP Pavillion x360 convertible. I have installed the Dolphin emulator (i am not asking for help with it). and would like to homebrew it. But it only accepts .raw images, so in order to Homebrew the emulator, I will need to mount the .raw image. I've tried mount, cant figure out how to do it. I've tried using poweriso to (maybe) mount it, but it doesn't start. How can i mount this .raw image? (i have used a special tool to make it have real storage.)

Re: How do i mount a .raw image?

Try adding the `-o loop` option to the mount command

# mount -o loop your-file.img /mnt

Also make sure that .img has a file system, it is supported (if not, install the appropriate package), as well as that the file system is not damaged.
P.S.: For example, amd-ucode.img cannot be mounted

Try adding the `-o loop` option to the mount command

The mount command automatically creates a loop device from a regular file if a filesystem type is not specified or the filesystem is known

@OP: I have no experience of emulator images for Dolphin but for raw disk images with partitions partx(8) can be used to find the starting sector of the target partition, which can be passed to `mount` with the offset option.

Here's an example:

~$ partx disk.img
NR   START      END SECTORS SIZE NAME                 UUID
 1    2048  1050623 1048576 512M EFI system partition 6a0625e3-23f0-42f0-8539-48a19c569214
 2 1050624 10483711 9433088 4.5G Linux filesystem     2aa90bdc-4a6c-470c-834a-1f69cbbf6e4d
~$ doas mount -o offset=$((1050624*512)) disk.img /mnt
~$ findmnt /mnt
TARGET SOURCE     FSTYPE OPTIONS
/mnt   /dev/loop0 btrfs  rw,relatime,ssd,discard=async,space_cache=v2,subvolid=5,subvol=/
~$

Additionally, if it contains a partition scheme that follows the Discoverable Partitions Specification, it should be possible to automatically mount it with systemd-dissect.

There's also

-P, --partscan
     Force the kernel to scan the partition table on a newly created loop device. Note that the partition table parsing depends on sector sizes. The default is sector size is 512 bytes, otherwise you need to use the option --sector-size together with --partscan.

If the image contains somewhat sensible data

file /path/to/image.raw

might get you an idea what you're dealing with.
