Hash not found just means I can’t find that particular rom in my hash DB. It is either from a system I haven’t added, isn’t in no-intro DB, or is slightly different from the version no-intro has.

If there were permission issues you’d see ERR: error processing resident evil 3.bin: open resident evil 3.bin: permission denied.

If I had to guess from the rom name this is PSX which I’m in the process of adding support for. The script tries .bin because that is the extension for several other systems but I’ll be adding bin/cue support for PSX.
