How to reproduce the issue:

Launch the core with a 7z compressed ISO.

Last known version to work:

none

PC specifications:

see log

[Sanaki]

Looks like you attempted to load the 7z directly, presumably via command line. 7z isn't a supported extension of the core, so this is somewhat expected from any unsupported random data. The only real improvement possible would be gracefully exiting rather than crashing. There's a reason the frontend wouldn't allow this by default. The only supported compressed formats for the core (in order of general preference) are chd, cso, and gz. Of those, gz will have to produce an index on run to allow direct seeking, and it'll run slower than the other two.

While retroarch theoretically could load the file via browse by extracting it to cache to be run, in practice this isn't advisable (or often even functional) for any optical images, especially with ones the size of PS2's DVDs. I recommend converting to chd if you want to use compressed files.
