Modding Civ I - Default Game settings

[darkpanda]

Tired of manually disabling the "Instant Advice" or enabling "End Of Turn" when you start a new Civ game ?

Here is how to hack your CIV.EXE to modify the default game settings when Civ starts a new game:

• The default game settings are stored a single byte, where each bit is an ON/OFF flag for one of the 8 game settings (see the SVE reference data for the meaning of each flag)
• this byte is located at offset 0x2FAF2 in version EN 474.01 of Civ, and offset 0x2FAF7 in version EN 474.05:

  0002FAF2h:   C7 06 C0 19 [B][COLOR="Red"]FA[/COLOR][/B] 00

• As you can see, the default value is 0xFA, written as 11111010 in binary notation; change it to your liking and play!

Note: if you chose to play without Sound, Civ will automatically disable the Sound flag later on...

Quite useful!

For quicker reference (hope you don't mind darkpanda)

The value is a sum of the following flags:

0x01 Instant advice
0x02 Auto-save
0x04 End of turn
0x08 Animations
0x10 Sound
0x20 Enemy moves
0x40 Civilopedia text
0x80 Palace

e.g. 0x02+0x04+0x10 = 0x16 for Auto-save, End of turn, Sound on, and everything else off.

(mind you, 0x02+0x08 = 0x0A, 0x04+0x08=0x0C etc.)

Note: Selecting "Chieftain" difficulty will enable Instant advice, regardless of the set value.

PS: EN v474.05 - the byte (itself) is at 0x2FAFB

No problem Renergy

Thanks for adding pointers! I sometimes rush to post things and don't/cannot take the time to explain them properly... So it's all good
