I am trying to mod Avatar Adventures Online. Yes I know you can mod the Credits/money, rank and the amount of Items. What I am trying to do is mod the Proficiency Points. Every time I try to mod my Proficiency Points the whole gamesaves resets, back to level 1. I have met someone about 6 months ago and he was able to mod this. He told me I had to figure out the Checksum within the gamesave. My question is how do you bypass the checksum or how to calculate the checksums? I would like to learn how to do this NOT just doing it for me. Thanks for your time. My Game Save Download: http://www.mediafire.com/download/clxzemkkae4jcj0/SuperJumps117.xml This Part of the gamesave code I believe is the checksum: <IBN5100FileArray> <int>8877</int> <int>6989</int> <int>6294</int> <int>4357</int> </IBN5100FileArray> </tutorialLessonDisplayed> <proficiencyCredits>0</proficiencyCredits> <proficiencyTotalBP>10035</proficiencyTotalBP> <proficiencyHPBoostUpgrades>65</proficiencyHPBoostUpgrades> <proficiencyAPBoostUpgrades>65</proficiencyAPBoostUpgrades> <proficiencyHealingUpgrades>0</proficiencyHealingUpgrades> <proficiencyMovementSpeedUpgrades>20</proficiencyMovementSpeedUpgrades> <proficiencyItemSpeedUpgrades>2</proficiencyItemSpeedUpgrades> <proficiencyItemStrengthUpgrades>0</proficiencyItemStrengthUpgrades> <proficiencyEnhanceDurationUpgrades>20</proficiencyEnhanceDurationUpgrades> <proficiencyEnfeebleResistUpgrades>20</proficiencyEnfeebleResistUpgrades> <proficiencyMoneyDropUpgrades>18</proficiencyMoneyDropUpgrades> <proficiencyItemDropUpgrades>3</proficiencyItemDropUpgrades> <WorldLineDivergenceMeter>0.077953</WorldLineDivergenceMeter> <IBN5100FileArray> <int>8877</int> <int>6989</int> <int>6294</int> <int>4357</int> </IBN5100FileArray> <trialsPreviouslyCompleted> Willing to Pay $20.00 (PayPal) to teach me how to bypass this.
