tszcheetah: To use the browser work-around with the current version of the plugin (0.34):
1. Quit GOG Galaxy completely.
2. In your browser log in at store.playstation.com, then go to
https://ca.account.sony.com/api/v1/ssocookie and copy the npsso value.
3. Open C:\Users\<username\AppData\Local\GOG.com\Galaxy\plugins\installed\psn_<guid>\plugin.py in a text editor.
4. Replace line 52 ("return NextStep("web_session", AUTH_PARAMS)" with the following line (make sure to get the indentation correct: there's 12 spaces in front of the line):
stored_cookies = {"npsso": "<paste npsso value from browser here>"}
This line follows the "if not stored_cookies:" line on line 51
5. Save the file, restart Galaxy
6. Go to the settings and reconnect the PSN plugin
Just tried this and it still works, you just need to disconnect an re-connect once or twice to get it to work.
This is the full block of code in plugin.py i am using now with Galaxy 2.0.64 latest version as of 23/05/2023 with plugin version 0.35.0.0
