How to modify Temple Run 2 save game data

PoC

1. JSON Game Data:

var gamedata = {"hash":"52260a1b3dd69ed623b5fbb045bf2b06","data":{"version":7,"Players":[{"v":1,"pid":1,"bestScore":1981650,"bestScoreNoResurrection":456180,"bestCoinScore":3857,"bestSpecialCurrencyScore":2,"bestDistanceScore":10270,"lifetimePlays":109,"lifetimeCoins":57585,"lifetimeSpecialCurrency":23,"lifetimeDistance":224673,"coinCount":1085,"specialCurrencyCount":1,"activePlayerCharacter":0,"gameCenterNeedsUpdate":true,"artifactsPurchased":[0,1,5,6,2,3,10,25,7,4,11,8,35,36,30,26,20],"artifactsDiscovered":[],"objectives":[2,1,0,6,5,3,4,7,9,11,10,8,16,17,18,14,23,24,22,21],"powersPurchased":[0,4],"randomSeed":-1118273536,"numberResurectsUsed":0,"hashID":null,"Buffs":[],"objectivesActiveData":[{"Title":"9 Lives","IconNamePre":"","IconName":"","DescriptionPre":"Use 'Save Me' 9 times","Description":"Used 'Save Me' 9 times","Points":1,"Hidden":false,"CanEarnMoreThanOnce":false,"Difficulty":30,"T":"Resurrects","TT":"OverTime","FT":"None","SV":9,"EarnedSV":6,"PID":27,"GCID":"com.imangi.templerun2.saveme9overtime"},{"Title":"Power Collector","IconNamePre":"","IconName":"","DescriptionPre":"Unlock a 2nd powerup","Description":"Unlock a 2nd powerup","Points":0,"Hidden":false,"CanEarnMoreThanOnce":false,"Difficulty":15,"T":"UnlockPowerups","TT":"PerRun","FT":"None","SV":2,"EarnedSV":1,"PID":12,"GCID":"com.imangi.templerun2.unlockpowerup2"},{"Title":"Allergic to Gold","IconNamePre":"","IconName":"","DescriptionPre":"1,000m collecting no coins","Description":"1,000m collecting no coins","Points":1,"Hidden":false,"CanEarnMoreThanOnce":false,"Difficulty":20,"T":"Distance","TT":"PerRun","FT":"WithoutCoins","SV":1000,"EarnedSV":0,"PID":15,"GCID":"com.imangi.templerun2.distance1000nocoins"}]}],"Characters":[{"v":1,"displayname":"Guy Dangerous","cid":0,"gear":[0,-1,-1,-1],"u":true,"uc":1200,"ct":"Coin","pvi":0,"art":[-1,-1,-1],"pid":0},{"v":1,"displayname":"Scarlett Fox","cid":1,"gear":[0,-1,-1,-1],"u":false,"uc":5000,"ct":"Coin","pvi":1,"art":[-1,-1,-1],"pid":0},{"v":1,"displayname":"Barry Bones","cid":2,"gear":[0,-1,-1,-1],"u":false,"uc":15000,"ct":"Coin","pvi":2,"art":[-1,-1,-1],"pid":0},{"v":1,"displayname":"Karma Lee","cid":3,"gear":[0,-1,-1,-1],"u":false,"uc":25000,"ct":"Coin","pvi":3,"art":[-1,-1,-1],"pid":0},{"v":1,"displayname":"Montanna Smith","cid":4,"gear":[0,-1,-1,-1],"u":false,"uc":25000,"ct":"Coin","pvi":4,"art":[-1,-1,-1],"pid":0},{"v":1,"displayname":"Francisco Montoya","cid":5,"gear":[0,-1,-1,-1],"u":false,"uc":25000,"ct":"Coin","pvi":5,"art":[-1,-1,-1],"pid":0},{"v":1,"displayname":"Zack Wonder","cid":6,"gear":[0,-1,-1,-1],"u":false,"uc":25000,"ct":"Coin","pvi":6,"art":[-1,-1,-1],"pid":0}],"ShowTutorial":false,"SMT":false,"ShowFriendMarkers":false,"SoundVolume":0.5,"MusicVolume":0.5,"LikeFB":false,"LikeTw":false,"LastPromoNumber":0,"TwitterURL":"http://bit.ly/TempleRun2Android","TwitterMessage":"I got {0} points while escaping from a Giant Demon Monkey.

2. How to compute hash:

hash = MD5(gamedata["data"] + "BonusItemProtoData");

3. ^_^

Thanks!
Genius Work!

How in the world do you use this? Does the "data" var in the hash generation include the brackets, or... what am I missing? And what is the "BonusItemProtoData"?

This doesn't appear to be the right salt, any ideas? http://jsfiddle.net/XLYDe/

which language is this?..

Excellent. Works for TR:Oz as well.

For those that couldn't get it to work, try something like this:

1. back up your current "stats.sav" file (at least that's what it's named for TR:Oz)
2. open stats.sav using your favorite text editor
3. copy this portion of the file to a new file to hash: {"version":.......} (do not include the very last curly brace in the file.)
4. at the end of the file copy the text "BonusItemProtoData" (without quotes).
5. now your hash file looks like this: {"version":.......}BonusItemProtoData
6. make the changes you desire (i can confirm that modifying coinCount and specialCurrencyCount work for TR:Oz)
7. save the file and hash it using md5
8. copy your changes and the new md5 to your stats.sav file (but not the BonusItemProtoData text)
9. save the new stats.sav file
10. make sure that TR:Oz is killed (not running) (not 100% sure this is necessary)
11. clear data on TR:Oz (not 100% sure this is necessary) and copy the stats.sav file to correct directory

Hopefully this helps someone.

@roycef:

The way you use the gamedata variable it's an object, so you need to convert it to a string first (JSON.stringify())

This one is working: http://jsfiddle.net/XLYDe/74/
Just copy in your modified gamedata.txt content and run it!

If I would like to add coins and gems according to my requirement for e.g. 10000 coins and 2000 gems then what should I write in the hash and in the remaining coding. Please tell me..
And also what is MD5.

Thanks..
It Works..!
