NOTE: You should enable string representation (in the memory editor). You should also have atleast some basic knowledge of GG, otherwise you might not understand somethings that are discussed below.
Ever wondered how you could get any pack that you wanted? Well now you can and for that follow the method given below.
For this you must go to the VIP LOYALTY PACKS tab (as shown in the picture below) and search for the pack's loyalty points. I used Oviraptor's pack as an example so I searched for 50000 (which is the amount of loyalty points to obtain this pack) as DWORD. (For good reasons I chose this pack as to not complicate things). If you are not a VIP (or don't have a VIP subscription), then, you can try this on the Henodus pack (pictured below), could be a different pack in your game.
You will end up with 130 or more results. Then use increment by 1 and close and re-open the loyalty packs screen. See what your new value of your pack is and save it, then revert other values and delete them. Change your saved value to either 0 or 1, then, go to it's memory address and scroll 30 to 31 addresses above your value to find your pack id (as can be seen in the picture below). There will be six addresses that look something like the picture below, you can also see that we have the string .Ovirapt present here. You need to change these 6 addresses to the pack that you want, let's find out how we can do that.
Now you will have to look for the pack that you want, I am going to go for Indominus Rex Gen 2 pack (for some strong reasons). So now you will need to search using the UTF-8 search. You need to search the string HIndom2 and you will end up with a lot of results. Check in these results if you find the string .HIndom2 and some values that look similar to the values as shown in the picture below in TYPE 1. If you find these values, then, select these 6 values and copy them, then, paste these values on your Oviraptor pack id that you found before (as shown in the picture above).
Remember that pack id's should look exactly like how they are shown in the picture below in TYPE 1 and TYPE 2 (values could be different but the presentation should look exactly the same). TYPE 1 is Indominus Rex Gen 2 pack (with string .HIndom2) and TYPE 2 is a different pack.
Once successfully done, then, close and re-open your VIP LOYALTY PACKS tab and you will see the change for yourself (as shown in the picture below), buy it and enjoy!
IMPORTANT INFORMATION: There is no specific way to find all pack id's (since some pack id's do not have strings but have numbers instead of strings as can be seen in the first two addresses of TYPE 2 of the 3rd photo). The one easy way to find them is to first find the Indominus Rex Gen 2 id from string HIndom2 and then look above and below this id to find other pack id's. Hope this helps. Enjoy!
