Recently I have been trying to play my old games (Worms, Sims, Black & White, etc..) on my Steam Deck.

I created an ISO of the various CD's via the dd command, but I have noticed Crossover doesn't support ISO. I needed to mount the ISO to a location.

This worked to install the game but fails copy protection. If I connect a USB DVD drive it detects the disc and works but this isn't particularly helpful.

Does anyone know what I should be setting or doing so the game sees the ISO or ISO mount as the disc?

A lot of the games I want to play simply don't have a steam version to buy
