Breeding A Gold With Maxed Stats (No Racing)

To begin with, a shout out to BrutalAl who originally discovered the use of RNG manipulation[gamefaqs.gamespot.com] for Chocobo breeding back in 2010 (along with Terence Fergusson and a few others).
Click this link[thelifestream.net] for the original post for this guide, made in August 2017.

Throughout this guide, you will be maxing out all stats for all five colours of Chocobos, without using hacks (you can optionally just max out the Gold Chocobo if you wish). You will exploit the broken RNG mechanics to breed precisely 12 times (8 times if just maxing out the Gold), and by the end you will have a set of Chocobos that all share the following internal stats:

MDash = 6000 (Top Sprint = 176 KPH)
MRun = 5900 (Normal Running Speed = 173 KPH)
Stamina = 9999 (Stamina = 999)
Intelligence = 100
Coop = 100
Acceleration = 80
Type = Wonderful
Personality = 2 (Dashing while in the lobby screen at the races).

Unlike most other areas in FFVII, the field RNG marker does not increment when standing in the "Stables" screen, which means the "randomness" isn't actually random, and the internal RNG can be manipulated to produce a Chocobo with predetermined results.

When you perform a hard reset, the Field RNG Marker will reset to 0. The highest value it can reach is 255, after which it will reset back to 0 again. This means that there are 256 different possible outcomes when breeding two specific Chocobos, and the purpose of this guide is to pinpoint the RNG value needed to produce the "best" possible outcome for each stage of the breeding process.

We can perform set actions which increase the Field RNG by a determined value:

Entering the Pen Area ------ +2
Feeding Krakka Greens ----- +1
Feeding Tantal Greens ------ +3
Feeding Reagan Greens ----- +6
Feeding Sylkis Greens ------- +7

Other greens also affect the Field RNG; however, the above list cites only the ones that we will be using for RNG manipulations. Releasing a Chocobo does not affect the RNG, although moving and breeding do, and the amount that the RNG increases by varies depending on certain factors (primarily the RNG value at the time of breeding/moving).

Bear in mind that this method is fairly extensive, and getting a maxed out Chocobo is more of a novelty than anything; mainly for those looking to extend their 'Perfect Save File'.
If you're looking for a "No Race Gold Chocobo Guide" that takes significantly less time, then check out this link[pastebin.com] (the Gold Chocobo will have 158 kph Sprint, and 125 kph Run).

Also, just for fun, I created another RNG method whereby a Terrible Chocobo's running speed (which will be close to max run speed) is considerably faster than its sprinting speed, achieved by exploiting an oversight in the coding - check this link[pastebin.com] if you're interested (105 kph Sprint, 168 kph Run). Normally there are safeguards in place to prevent a Chocobo's running speed being greater than it's sprinting speed.

Note that this is the 2nd version of this guide. In the first version[gamefaqs.gamespot.com], racing was required, none of the Chocobos were personality 2 (dashing while in the race lobby screen), and most of them were "Great". In this current version, no racing is needed, all Chocobos are Wonderful, all Personality 2, and also fewer Greens were used (although one more breed was required).

Lastly, the stats we are focusing on maxing are MDash and MRun, as these are the only stats that cannot be boosted by feeding Greens; all other stats are easy to max out. For more info on Chocobo stats, visit this topic[forums.qhimm.com] by Terence Fergusson.

• All 6 stables purchased (and empty)
  
• 1 x Captured Wonderful Chocobo in the pen - Icicle Area alongside 1x or 2x Jumping (rabbit enemy)
  
• 1 x Captured Great Chocobos in the pen - Mideel alongside 1x or 2x Spiral
  
• 1 x Captured Chocobo of any type in the pen
  
• 99 Sylkis Greens in inventory (287 needed in total). Bought from the Chocobo Sage
  
• 5 Reagan Greens. Bought from the Chocobo Sage
  
• 99 Mimett Greens in inventory (103 needed in total). Bought from Chocobo Billy
  
• 4 Tantal Greens. Bought from Chocobo Billy
  
• 25 Krakka Greens. Bought from Chocobo Billy
  
• 3 Carob Nuts. Stolen from Vlakorados near Bone Village
  
• 9 Zeio Nuts. Stolen from the Goblins on Goblin Island
  
• 976,000 reserve gil for the remaining Greens

In total, you'll need 1,611,850 gil to cover the cost of all the Greens. One x Mastered All sells for 1,400,000 (as if you didn't already know)!

To my knowledge, this method should work on every release of FFVII. I haven't tested this on each version, but my understanding is that the field scripts pertaining to Chocobo breeding mechanics are identical across all releases of the game.

YOU MUST perform a hard reset (as opposed to a soft reset) when instructed to do so, which means completely resetting your PS1 (as opposed to holding the shoulder buttons + start + select), or, closing down the app you are using and rebooting it. This way the RNG will reset to 0 each time.

Battling on the World Map will not affect the field RNG, nor will purchasing Greens from Billy. It is important to note, however, that you must not linger around in the 'Pen' area (screen where you store your caught Chocobos prior to moving them into the Stables); this is due to the fact that after about 4 seconds or so, the RNG will begin to advance by two roughly every 2 seconds while on this screen.
ALWAYS run into the Stables (2nd screen) as quickly as you can from the Pen area (1st screen). You do have a bit of leeway; it doesn't need to be a perfect sprint, just don't hang around. Note that you do not need to save as close as possible to the Chocobo Farm from the World Map (as some RNG manip guides mistakenly advise), as the field RNG will not increment while on the World Map.

Additionally, we do not need to race using this method, which means you can start and finish this as soon as you obtain the Highwind (before the Gold Saucer reopens), if you wish. The only downside to this is the fact that you won't be able to check your stats as you go along, which is a necessary step. I suggest only getting to step 12 until the Gold Saucer opens. When you test your Chocobos in the races to confirm stats, be sure not to actually race them as it will affect the RNG dice roll when breeding.

So, you have all the items as listed above, and you're ready to go? Excellent. Make a fresh save on the World Map outside the Chocobo Farm and let's go!

You should have a Wonderful, Great and "spare" Chocobo of any type waiting in the pen area. It is important to note that you must have an empty barn at this point, as the stable positions that the Chocobos are moved/bred into matter. You must follow these instructions exactly, i.e. when instructed to release a Chocobo, make sure to do so. Any deviation from these steps will likely cause inconsistent results.

Also, I shall be instructing you on how to name your Chocobos for the sake of reference. Once you get to the final breeds, you'll be free to label them as you wish. Pay no mind to the RNG values cited, these are listed to allow me to error check my work.

1 -- Hard reset and run into the barn (without hanging around in the "Pen" area). RNG @ 002
2 -- Move the Chocobo of any type in (will be female, call this "Choco"). RNG @ 014
3 -- Feed "Choco" 21 Sylkis Greens. RNG @ 161
4 -- @ 161 Move the Wonderful Chocobo (will be female, Call "WF"). RNG @ 173
5 -- Release "Choco". RNG @ 173
6 -- Feed "WF" 3 Sylkis Greens. RNG @ 194
7 -- Feed "WF" 2 Krakka Greens. RNG @ 196
8 -- @ 196 Move the Great Chocobo (male - "GM"). RNG @ 208

Before doing anything else, we'll need to max out Acceleration using Mimett Greens. Buying Greens from Chocobo Billy will not have any effect on the RNG. Make sure to continue without having left the Stables screen, with the RNG still @ 208.

9 -- Feed "WF" 33 Mimett Greens. RNG @ 051
10 -- Buy 4 Mimmet Greens, then feed "GM" 70 Mimett Greens. RNG @ 005

Note that when feeding Mimett Greens you have a 75% chance it'll increase Acceleration by 0, and a 25% chance it'll increase it by 1, which is why we need to feed them so many. When you breed, the offspring will have an Acceleration stat equal to the average Accel value of its parents, so if both parents have maxed Accel at this stage then every subsequent offspring will also have maxed Accel.

Now to quickly max Dash and Run. Carrying on from RNG @ 005:

11 -- Feed "WF" 1 Sylkis Green. RNG @ 012
12 -- Feed "GM" 1 Sylkis Green. RNG @ 019

Here are our current stats:

MDash = 4011, MRun = 3811, Stam = 3814, INT = 59, Acc = 80, Coop = 84, (P2)
Sprint Speed = 117 KPH | Normal Speed = 112 KPH | Stamina = 381 MDash = 3554, MRun = 3254, Stam = 3041, INT = 51, Acc = 80, Coop = 100, (P1)
Sprint Speed = 104 KPH | Normal Speed = 95 KPH | Stamina = 304

Now it's time to check your stats at the races to make sure they match up (you won't be able to verify your Normal Running Speed, just Sprint Speed and Stamina). To play it safe, save before heading to the Gold Saucer then reload your save after verifying your Chocobo's stats. This way you'll keep the race count at 0 for each Chocobo.

Note that (P1) and (P2) stand for Personality Type - Personality Types 0 and 1 will give a normal running Chocobo animation on the lobby screen at the races, and Personality Type 2 will give a sprinting (or 'dashing') animation. This is the only thing that Personality Type affects - for the most part, it is a dummied out feature and doesn't have any affect at all on the performance of the Chocobo whatsoever (it does have a slight affect on the breeding RNG dice roll, but not in a way that really matters).

If for some reason the Sprint Speed / Stamina / Personality Type does not match up with the stats as shown, then it means you have made a mistake somewhere and will need to reset from your most recent save. I suggest saving into a new save slot each time you save to avoid having to restart the whole process.

An error will likely have come from standing in the 'Pen Area' (1st screen) for too long, or from having fed the incorrect amount of greens. Note that running into the Pen Area will always advance the RNG by 2, so do not leave the Stables (2nd screen) until instructed to do so. Releasing a Chocobo when not instructed to, or selecting the wrong parent first when mating will also cause inconsistencies.

Sidenote - If you are wandering why we are able to produce a coloured chocobo without needing to race, it is due to the fact that normally you would need a combined win of 4 races between the parents to have a 100% (256/256) chance of getting a coloured chocobo at the first mating stage when using a Carob Nut.
If the parents have won less than 4 races, then you will still have a 35% (90/256) chance to get a coloured chocobo with a Carob Nut - 17.6% (45/256) chance for it to be Green, and 17.6% (45/256) chance for it to be Blue. This ONLY applies when breeding either 2x Great chocobos, 2x Good chocobos, or 1x Great with 1x Good.

If breeding a Great or Good chocobo with a chocobo that isn't a Great or Good (such as a Wonderful chocobo as we will be doing), then the above chances will only occur following a preliminary 25% (64/256) dice roll, so long as the Great or Good chocobo is selected first (if the 25% chance fails, or the Great/Good chocobo is selected 2nd, then the offspring will always be Yellow). This means that there are only 23 (approx) RNG values out of the available 256 that produce a coloured Chocobo when breeding a Great with a Wonderful (less than 4 races won, using a Carob Nut, and selecting the Great chocobo first).

Through testing via Cheat Engine, I have found all RNG values that produce a Green chocobo, and chosen the one that gives the best stats possible. I have then gone through all remaining RNG values that produces a Blue chocobo, selecting one that is the opposite sex to the Green and also having the best stats available.

13 -- Save outside the Ranch, hard reset and run into the barn (without hanging around in the "Pen" area). RNG @ 002
14 -- Feed "WF" 10 Sylkis Greens. RNG @ 072
15 -- Feed "WF" 2 Krakka Greens. RNG @ 074
16 -- @ 074 Mate two Chocobos selecting "WF" first using a Zeio Nut. RNG @ 086 (Great Male - "GM2")
17 -- Release "GM" in stable 2 (not the newborn "GM2" in stable 3)
18 -- Feed "GM2" 3 Sylkis Greens. RNG @ 107

Here are the stats of the newborn Great male:

MDash = 4412, MRun = 4287, Stam = 5188, INT = 82, Acc = 80, Coop = 12, (P2)
Sprint Speed = 129 KPH | Normal Speed = 126 KPH | Stamina = 518

"WF" ----- 10 battles
"GM2" ---- 17 battles

Now run outside and fight 17 battles, then save. Before resetting, check "GM2"s stats at the races.

Note - You only need to fight 17 battles as a minimum, meaning, you can fight more if you wish. You are okay to carry on with the story and come back to breeding later on, as there will be 10 intervals in which you must leave to battle.

19 -- Hard reset and run into the barn (without hanging around in the "Pen" area). RNG @ 002
20 -- Feed "GM2" 18 Sylkis Greens. RNG @ 128
21 -- Feed "GM2" 1 Reagan Green. RNG @ 134
22 -- @ 134 Mate two Chocobos selecting "GM2" first using a Carob Nut. RNG @ 147 (Green female - "GNF")
23 -- Feed "GNF" 2 Sylkis Greens. RNG @ 161

Here are the stats of the Green female.

MDash = 5753, MRun = 3149, Stam = 6350, INT = 100, Acc = 80, Coop = 8, (P2)
Sprint Speed = 169 KPH | Normal Speed = 92 KPH | Stamina = 635

"WF" ----- 7 battles
"GM2" ---- 5 battles
"GNF" ---- 17 battles

Now run outside and fight 17 battles, then save. Before resetting, check "GNF"s stats at the races.

24 -- Hard reset and run into the barn (without hanging around in the "Pen" area). RNG @ 002
25 -- Feed "GNF" 11 Sylkis Green. RNG @ 079
26 -- Feed "GNF" 5 Krakka Greens. RNG @ 084
27 -- @ 084 Mate "GNF" and "GM2" using a Carob Nut. RNG @ 095 (Blue male - "Blu M") (it doesn't matter which one you select first)
28 -- Release "GM2". RNG @ 095
29 -- Feed "Blu M" 3 Sylkis Greens. RNG @ 116
30 -- Head over to the Chocobo Sage and refill on Sylkis Greens (leave with 99).

Here are the stats of the Blue male:

MDash = 5082, MRun = 4715, Stam = 8807, INT = 100, Acc = 80, Coop = 12, (P2)
Sprint Speed = 149 KPH | Normal Speed = 138 KPH | Stamina = 880

"GNF" ---- 3 battles
"Blu M" ---- 9 battles

Now run outside and fight 9 battles, then save. Before resetting, check "Blu M"s stats at the races.

Sidenote - If mating a Green and Blue chocobo using a Carob Nut, then you would normally need 9 combined races to have a 100% (256/256) chance to produce a Black chocobo.

If the parents have won less than 9 races, then you will have a 3.9% (10/256) chance to get a Black when using a Carob Nut. Again, I have looked at all 10 RNG values that produce a Black chocobo at this stage, and chosen the one that gives the best stats available.

31 -- Hard reset and run into the barn (without hanging around in the "Pen" area). RNG @ 002
32 -- Feed "Blu M" 30 Sylkis Green. RNG @ 212
33 -- Feed "Blu M" 1 Krakka Green. RNG @ 213
34 -- @ 213 Mate "Blu M" and "GNF" using a Carob Nut. RNG @ 225 (Black female - "Blk F") (It doesn't matter which one you select first)
35 -- Feed "Blk F" 3 Sylkis Greens. RNG @ 246

Here are the stats of the Black female:

MDash = 5417, MRun = 5186, Stam = 9505, INT = 100, Acc = 80, Coop = 12, (P2)
Sprint Speed = 159 KPH | Normal Speed = 152 KPH | Stamina = 950

"GNF" ---- 6 battles
"Blu M" ---- 7 battles
"Blk F" ---- 9 battles

Now run outside and fight 9 battles, then save. Before resetting, check "Blk F"s stats at the races.

36 -- Hard reset and run into the barn (without hanging around in the "Pen" area). RNG @ 002
37 -- Feed "Blk F" 6 Sylkis Green. RNG @ 044
38 -- Feed "Blk F" 1 Reagan Green. RNG @ 050
39 -- @ 050 Mate "Blk F" and "Blu M" selecting "Blk F" first using a Zeio Nut. RNG @ 062 (Black male - "Blk M")
40 -- Release "Blk F". RNG @ 062
41 -- Feed "Blk M" 2 Sylkis Greens. RNG @ 076

Here are the stats of the Black male:

MDash = 5958, MRun = 5834, Stam = 9999, INT = 100, Acc = 80, Coop = 8, (P2)
Sprint Speed = 175 KPH | Normal Speed = 171 KPH | Stamina = 999

"Blu M" ---- 3 battles
"Blk M" ---- 16 battles

Now run outside and fight 16 battles, then save. Before resetting, check "Blk M"s stats at the races.

Sidenote - When mating a Black and Wonderful chocobo with a Zeio Nut, you would need 12 combined races between the parents to have a 100% (256/256) chance to get a Gold. If less than 12 races have been won, then you will have a 3.1% (8/256) chance to get a Gold.

42 -- Hard reset and run into the barn (without hanging around in the "Pen" area). RNG @ 002
43 -- Feed "Blk M" 25 Sylkis Greens. RNG @ 177
44 -- Feed "Blk M" 5 Krakka Greens. RNG @ 182
45 -- @182 Mate "Blk M" and "WF" selecting "Blk M" first using a Zeio Nut. RNG @ 194 (Gold male - "GDM")
46 -- Feed "GDM" 1 Sylkis Green. RNG @ 201

Here are the stats of the Gold male:

MDash = 5013, MRun = 5000, Stam = 9999, INT = 100, Acc = 80, Coop = 4, (P2)
Sprint Speed = 147 KPH | Normal Speed = 147 KPH | Stamina = 999

"WF" ---- 5 battles
"Blk M" ---- 7 battles
"GDM" ---- 11 battles

Now run outside and fight 11 battles, then save. Before resetting, check "GDM"s stats at the races.

47 -- Hard reset and run into the barn (without hanging around in the "Pen" area). RNG @ 002
48 -- Feed "GDM" 5 Krakka Greens. RNG @ 007
49 -- @ 007 Mate "GDM" and "WF" selecting "WF" first using a Zeio Nut. RNG @ 021 (Gold female - "GDF")
50 -- Release "GDM". RNG @ 021
51 -- Feed "GDF" 2 Sylkis Greens. RNG @ 035
52 -- Head over to the Chocobo Sage and refill on Sylkis Greens (leave with 99).

Here are the stats of the Gold female:

MDash = 5386, MRun = 4405, Stam = 9999, INT = 99, Acc = 80, Coop = 8, (P1)
Sprint Speed = 158 KPH | Normal Speed = 129 KPH | Stamina = 999

"WF" ---- 10 battles
"GDF" ---- 13 battles

Now run outside and fight 13 battles, then save. Before resetting, check "GDF"s stats at the races.

This time when we breed, our Gold will be the keeper, so make sure to name it correctly (as with all breeds from this point on).

53 -- Hard reset and run into the barn (without hanging around in the "Pen" area). RNG @ 002
54 -- Feed "GDF" 6 Sylkis Greens. RNG @ 044
55 -- Feed "GDF" 1 Reagan Green. RNG @ 050
56 -- @ 050 Mate "Blk M" and "GDF" selecting "Blk M" first using a Zeio Nut. RNG @ 062 (Gold Male - name it whatever you wish)
57 -- Release "GDF". RNG @ 062
58 -- Feed the Gold Male 25 Sylkis Greens. RNG @ 195

Here are the stats of the Gold male:

MDash = 6000, MRun = 5900, Stam = 9999, INT = 100, Acc = 80, Coop = 100, (P2)
Sprint Speed = 176 KPH | Normal Speed = 173 KPH | Stamina = 999

"Blk M" ---- 5 battles
"Gold M" --- 16 battles

Congratulations! You now have a completely maxed out Gold Chocobo!! Now we must max out the other four Chocobos (so no racing just yet, unless you're not bothered about the four other birds). Note that they will all have the same stats as above.

Run outside and fight 5 battles, then save (if you fight more than 5 battles, keep note of how many additional battles you fought). Before resetting, check the Gold Male's stats at the races.

59 -- Hard reset and run into the barn (without hanging around in the "Pen" area). RNG @ 002
60 -- Feed the Gold Male 6 Sylkis Greens. RNG @ 044
61 -- Feed the Gold Male 1 Reagan Green. RNG @ 050
62 -- @ 050 Mate "Blk M" and "WF" selecting "Blk M" first using a Zeio Nut. RNG @ 062 (Black Male - name it whatever you wish)
63 -- Release "Blk M". RNG @ 062
64 -- Feed the new Black Male 14 Sylkis Greens to begin maxing Coop. RNG @ 160

"WF" ---- 3 battles
"Black M" ---- 16 battles

Run outside and fight 11 battles, then save. If you fought more than 5 battles earlier, then deduct the number of additional battles you fought from 11. Before resetting, check the Black Male's stats at the races.

65 -- Hard reset and run into the barn (without hanging around in the "Pen" area). RNG @ 002
66 -- Feed the Black Male 11 Sylkis Greens. RNG @ 079

68 -- @ 084 Mate the Gold Male and "GNF" selecting the Gold first using a Zeio Nut. RNG @ 097 (Green Female - name it whatever you wish)
69 -- Release "GNF". RNG @ 097
70 -- Feed the new Green Female 19 Sylkis Greens to begin maxing Coop. RNG @ 230
71 -- Head over to the Chocobo Sage for the last time and refill on Sylkis Greens (leave with 69).

"Gold M" ---- 6 battles
"Green F" -- 17 battles

Now run outside and fight 17 battles, then save. Before resetting, check the Green Female's stats at the races. We won't need to battle any more after this.

72 -- Hard reset and run into the barn (without hanging around in the "Pen" area). RNG @ 002
73 -- Feed the Green Female 6 Sylkis Greens. RNG @ 044
74 -- Feed the Green Female 1 Reagan Greens. RNG @ 050

76 -- Release "Blu M". RNG @ 062

For the final mate, we don't need to leave the barn this time. With the RNG still @ 062:

77 -- Feed the Blue Male 38 Sylkis Greens. RNG @ 072
78 -- Feed the Blue Male 4 Tantal Greens. RNG @ 084
79 -- @ 084 Mate "WF" and the Black Male selecting "WF" first using a Zeio Nut. RNG @ 097 (Wonderful Female - name it whatever you wish)
80 -- Release "WF". RNG @ 097
81 -- Feed the new Wonderful Female 25 Sylkis Greens. RNG @ 016

You now have a barn of maxed out Chocobos. Congrats! Now all that's left is to check Blue Male and Wonderful Female's stats, then race them all to S Class :)
