Should have asked before wasting all your credit lol.
Option 1.
Open GG, select the game, enter ur current credit value, change to Dword and scan. Spend some credits, open GG, enter the remaining credits, refine, at this point you should have just 1 or 2 values at best. if 2, just modify both to 99999. Visually your credits wont change, go to store, buy boosters, go back to your home page and your credits should now be 99999.
Option 2.
If you dont have enough credits to spend, first mod the manager experience with GG, which should also be Dword i believe, if not use Auto. Enter your current manager experience, play a match and gain more experience, enter new value, refine. Repeat until u get 1 or 2 values left, change value to 9999. VERY IMPORTANT; at this point dont play another match yet, save the experience value and do NEW SCAN for your current credits. Now you can play a match and level up to gain some credits. Refine for the new value and change to 99999 if you have only 1 or 2 left, otherwise, play another match to level up again and gain more credits.
PS: its better not to increase ur manager level to 10, cause its the maximum and you cant modify it in the future if you need to mod credits again., leave the manager level below 9 (thats why you save the experience value, so you can decrease it later.
Also dont forget that you need to buy boosters to see that the value has changed from 10 to 9999. After buying all the boosters and upgrading facilities and everything, close the game and reopen, otherwise the boosters wont show, but the sm credits will be back to 10, so make sure to buy as many boosters as you want
