How do you mean? You can export cheats from gamehacking and then use the import functionality of Duckstation.
If you mean for me to add all the cheats from Gamehacking into the DS cheat collection there are MANY problems with that but primarily I don't have their full PS1 database or permission from gamehacking to use it (and that's a showstopper as far as I'm concerned).
Manually adding & cleaning up cheats for individual games is doable (and the cleaning alone can be a lot of work) but it's not something I'm actively pursuing - people of course are free to add cheats and raise a PR on github.
