Nation-Specific Notes

  • Spain, Russia and England are designated as innately hostile towards France, which alters the outcomes of several functions.
  • In February each nation raises its aggression vs. France by an amount determined by the current scenario & their diplomacy status; England's aggression boost is doubled.
  • Every year a certain percentage of boats decay; England is immune from this.

Officer-Specific Notes

Personality Traits

The last byte of every officer's entry in ROM 0x3466A - 0x35758 encodes hidden personality traits which have multiple subtle effects on gameplay. These traits & their known effects are as follows:

  1. Simple, Calm, or none
  2. Coward, Courage, or none
  3. Charm or none
  4. Fortune or none
  5. Allegiance (Value from 0 to 3)
  • There are quotes that can randomly appear when viewing an Officer's page that are specific to his personality traits:
    • Simple: "Simplicity and clarity are two of my strong points"
    • Calm: "When I have my composure, I am always incredibly skillful"
    • Coward: "I want an end to this bloodshed!"
    • Courage: "I fear no one, and I will defeat all!"
    • Charm: "Charm is essential for a person who gives orders"
    • Fortune: "Good fortune smiles on me"
Simple (0x80)
  • When you deny an officer's request for an expedition, if that officer is Simple, there is a chance that he will disobey your orders and attack anyway. The chance of this is:
If that officer is also Courageous: 50%
Otherwise: (50-(floor(Loyalty/2)))%
Calm (0x40)
Coward (0x20)
  • Officers that are Cowardly will not lead attacks on other cities.
Courage (0x10)
  • Officers that are Courageous are more likely to launch attacks on adjacent cities, even when outnumbered.
Charm (0x08)
  • Officers that are Charming give a greater boost to their troops' Morale when giving a Speech.
Fortune (0x04)
  • Officers that are Fortunate cannot become war prisoners.
  • Officers that are Fortunate have a decreased chance of dying of old age each January.
Allegiance (0x03)
  • Officers with a max Allegiance value of 3 (Napoleon & his relatives) are playable in Scenario 4.
  • Officers with higher Allegiance values receive a larger Loyalty boost when Rewarded.
    • Possible officer quotes from being Rewarded are also affected by their Allegiance value.
  • Officers with higher Allegiance values are harder to recruit as POWs.
    • When an officer is successfully recruited, their starting Loyalty is randomly generated. The lower the officer's allegiance, the higher this number can be.
  • Officers with lower Allegiance values drop Loyalty at a faster rate & are more likely to defect.

Unused Code & Data

  • Italy is within the list of nations (ID 0x05), but does not exist as its own nation in the actual game.
  • The hidden 5th Scenario, Escape from Elba Island, was not included in the NES port, but several functions & data tables still reference its existence, presumably due to being ported directly from the original code.
