Please don't!
A snapshot (such as Z80) is a terrible format to preserve programs. We should avoid it whenever possible, except only as last resort, when an actual tape preservation cannot be obtained.
In a snapshot, you are basically cutting out the program initialization. Sometimes it's obvious what you be missing (such as losing the loading screen). Other times, problems can be more subtle. For instance, a game that generates scenarios with random elements, usually choose a random seed right at the beginning. If you load it from a tape image, it will generate a different scenario every time. But if you load it from a Z80 snapshot, the random seed was probably already chosen, so it will probably always generate exactly the same scenario.
Snapshots made sense a couple decades ago, when emulators couldn't handle custom loaders, or they took too long to load programs from tape. Nowadays, snapshots still make sense to save a game you are playing for instance, but not for software preservation.
