I just found something! While you cannot edit the ships in continue.sav directly, you can still put drones and weapons into cargo slots! Therefore, you can decipher the values of each weapon and drone by finding their values there!

Slight complaint: Since the Medbay and Hacking are in the same room, only one of them gets repaired (which happens to be the Medbay.)

Managed to kill the Rebel Flagship by waiting. That's how damn powerful the beam is.
