i managed to change number of packs, so basically price of the packs are 2000 less than the actual price. for instance, special packs cost 150000, so you need to search 148000 as dword. you will get several numbers, what you need to do is increment every value by 1 and then check which value overlaps with pack price. after that save the value and change it to -2000 (this will make pack cost 0 coins). following that click on that value in gameguardian then click "go to". search the d value that is the same number as number of special packs. voila now you have unlimited special packs. i will try to post a video on it
