In regards to settings for PS1 games it depends on the emulator and game. If it's a plugin based emulator like epsxe then there's more of a chance you'd have to change settings. Again it depends on the game. You could end up playing 20 different games without having to tweak anything for both systems - if you do run into problems then that's the time to look stuff up for that specific game and change any settings that are needed.
