Cannot mount ISO in KDE Dolphin

Help
1

I want to use a game that comes in an ISO file. In Dolphin there normally is a context menu entry to mount the ISO.

This happens with fuseiso afaik, which I added to my package list.

Do I need to change kernel modules or anything?

Using Plasma 6.x, NixOS unstable.

There seem to be 2 issues.

  1. Some .iso files are not recognized as such. Something with weird formats maybe?
  2. When trying to mount a correct ISO, i get

Error xxxx, filesysten type iso9660 not configured in kernel.

So I will see how I do that

Turns out Ark can view and extract ISOs, fine for me. Still would be nice to solve this
