Ok so Im testing stuff in Single player and Im running into a problem Codes are not exactly "unlimited" on Sp so if anyone knows how to say "Spawn in" Codes it would be helpful Id like to test the cores on some ships with them and such.
Use IONCROSS Freelancer Character Editor or edit data file - sell Codes at the base you want ( but beware, return modified data to original before go to server or you will get kicked because of bad installation)
