Final Fantasy I & II: Dawn of Souls: Critical Hit Rate Fix

Final Fantasy 1 on Famicom/NES was a pretty buggy game. Spells didn't work. Weapon traits didn't work. So on and so on.

One of the bugs that had a variable effect on the game was that the critical hit table for the game was looked for in the wrong place. Instead of looking at the critical hit rate for the weapon, the game would look at the index number of the weapon to determine actual critical hit rate.

So the Masamune gets 40 points into critical hits instead of 10. Thor Hammer should have had 1 point into critical hits, but instead got 36.

Unfortunately the people at Square-Enix only knew of a few bugs of the game to fix and never changed this in any later version. Or they did know about this bug and decided to leave it as is. Either way, the GBA version of the game retains this bug.

The first patch included fixes the original 40 weapons to their intended critical hit rates. The second uses the intended critical hit rates for the original 40 weapons to approximate what was intended for the new 24 weapons.

Final Fantasy 1 Critical Hit Rate Fix

Ever since the original Famicom version of Final Fantasy 1 there has existed a bug with regards to
critical hit rates for weapons. Instead of using the intended crit hit rate the game would refer
to the weapon's index number.

This patch fixes this with the weapon's intended crit hit rate from the Famicom/NES version.

This makes no attempt to balance anything nor does it do anything to the equipment new to Dawn of
Souls. You can apply both patches to the same ROM without any issue however.

The table below shows the index numbers versus the intended rate (which is what this patch
changes them to).

01 Nunchaku - 10
02 Knife - 5
03 Staff - 1
04 Rapier - 10
05 Hammer - 1
06 Broadsword - 5
07 Battle Axe - 3
08 Scimitar - 5
09 Iron Nunchaku - 10
10 Dagger - 5
11 Crosier - 1
12 Saber - 10
13 Longsword - 5
14 Great Axe - 3
15 Falchion - 5
16 Mythril Knife - 5
17 Mythril Sword - 5
18 Mythril Hammer - 1
19 Mythril Axe - 4
20 Flame Sword - 5
21 Ice Brand - 5
22 Wyrmkiller - 10
23 Great Sword - 5
24 Sun Blade - 5
25 Coral Sword - 10
26 Werebuster - 5
27 Rune Blade - 5
28 Power Staff - 1
29 Light Axe - 3
30 Healing Staff - 1
31 Mage's Staff - 1
32 Defender - 5
33 Wizard's Staff - 1
34 Vorpal Sword - 30
35 Cat Claws - 5
36 Thor's Hammer - 1
37 Razer - 10
38 Sasuke's Blade - 30
39 Excalibur - 5
40 Masamune - 10

As you can see, this is a signficant nerf to many of the late game weapons and ALL the hammers
and staves.
