Thanks for the link, but I already found a different tutorial from this thread - [Tutorial]Use the archive tool to uncompile *.arz and *.arc how to do it and now am extracting the files, now I’ll need to add them to the database manually though…
Anyway your link is really helpful, so thanks again for your help 
. Now hopefully I can mod everything I want to my liking and finally figured out how to unpack ARZ and ARC files 
EDIT:
I just noticed I already had everything already extracted, yet I didn’t know what the Gdx1 and Gdx2 folders were for, now thanks to you guys I know and I found the pet bonuses, so I’m happy.
Thank you all who replied for your help.
