Playing from mounted ISO image

jimbohaha

Hi,

Is it copy protection that prevents me from playing the Doom2/UltimateDoom by mounting an ISO image on my HDD with the loopback device in Linux or some other unfathomable problem? I get 0 playable games using this method but it works fine if I use the actual CD.

Can't seem to find the answer via google or searching on this forum or the wiki.

Thanks.

Please elaborate a little. How are you starting the game? Could you paste here your command line, for example, if that's what you're using.

I'm starting the games using Snowberry, it says version 1.5, and it was some time ago I built it... Arch Linux 64bit.

I'm just experimenting a bit, there's something peculiar going on...

3 partitons: / (ext3), /home (ext3), /mnt/Data (ext4). I put the ISO in /mnt/Data/ISO/Doom2.iso. I made the /mnt/Data/Doom/Doom2 mountpoint and mounted the Doom2.iso to it. My user had read permissions to access it. Doomsday would not detect DOOM2.WAD in that folder when selecting it. It wasn't a permissions problem: I copied preserving permissions to my home directory and then Doomsday would detect. Not sure if it didn't like it because it was a mount on a mount on a mount? But mounting it on a MP in my home folder worked so why not? I tried various permutations of permissions and copies under /mnt/Data and Doomsday wouldn't have any of it but would successfully detect a DOOM2.WAD on a NAS drive mounted via NFS. Doomsday didn't detect a WAD copied to /mnt either, but would happily detect a WAD copied under /Doom2.

Making a new mountpoint for the ISO under /mnt/ISO-mounts/Doom2 and mounting the ISO there and the WAD is detected so I'm happy now. Not sure why I don't just copy the WAD though rather than mess about with mounts and stuff.

if you set up doosday correctly AND pointed it to the main wad file it should work
