I'm in Germany but not German :) Couple of options which spring to mind.
Look for any shop which ends in KA - it's likely to be a second hand shop, they love second hand shops. Take it in there and offer it up.
Take it to Gamestop and ask if they will buy it from you. They probably won't take the PS1, but the PS2 possibly. But you might be lucky.
There is a chain called Feebay which will take your things and stick them on ebay for you and give you a percentage of the money back.
Look for a local facebook group or meetup.com page for english speaking people near you, and ask their advice/offer it for free. I've just asked on mine where to drop off electronics needing recycling and someone offered to pick it up and take it for me! :)
Keep an eye for when your nearest Kindergarten is having a flea market (flohmarkt) and donate it to sell.
Look for a refugee centre (Flüchtlingszentrum) and donate it there - lots of Syrian refugees in Germany at the moment, many of them teenagers/children. Usually refugee workers are skilled at communicating without any language, or you can just say "Für die Kinder" and it will be clear, anyway.
If you have an English Language library, give it to them. They often lease games and consoles.
When the weather forecast is dry, stick in the street with a note, defo. "Zu verschenken, ganz funktioniert" (To take, fully functioning)
Even better if you can find the Sperrmüll dates for your street, there will either be one every 6 months (you'll notice, because everyone will stick their old furniture on the street) or you'll have to call up and request one - in which case, wait until a neighbour does it, and piggyback theirs. This is accepted as a perfectly okay thing to do. Although it's probably more likely to be overlooked and end up in landfill this way than offering it randomly.
Lastly, go onto your city website and use Chrome to translate the page, find the page for waste and recycling, and find the electronics recycling centre and take them there.
Uhm, sorry, that ended up being quite a list!
