I think George can convert a registered game into an unregistered game, so you can load it in debug mode. You can send him your save file by PM or email

But you may not need to cheat. For one thing, it's difficult, if not impossible, to sell IDs, so you probably jettisoned it in a wreck, destroyed station, or container. If you know you had it recently, you could go back and look for it. Also, it's possible to beat the game without one. If you have a Black Market ID, and haven't made them angry, Black Market shipyards will install military items without military ID. Ringer shipyards (and maybe Taikon Ventures) will too, but you need to pay with rin, a separate currency you can obtain by selling items to Ringer or Teraton stations. You could try exploring ahead, avoiding enemies as much as possible, until you find some of these stations.
