1. get any AIM client (aim 1.x-5.x)
2. once you open the client go to setup
3. go to connection and enter oscarzie.1337.cx as server name.
4. now enter any screenname and username and you'll be able to use oscarzie!
NOTE: if you are on windows 10/11 delete aimapi.dll and aim will open.
use this custom installer that has the patches and has oscarzie as default server!
