Tested on Catan V 1.1 - rev; 17427 for steam, not sure will it work with other versions.
Basic table with number of cards.
This is my first trainer, so I hope it works for you.
Addresses usually need one turn to sync with game, so don't panic if you see value "?" when you attach process to table.
How to use this cheat table?
Install Cheat Engine
Double-click the .CT file in order to open it.
Click the PC icon in Cheat Engine in order to select the game process.
Keep the list.
Activate the trainer options by checking boxes or setting values from 0 to 1
It might work on other versions of game, but there is no guarantee.
If you find that table is working on other versions, please share here with others.
Thanks for this! Not sure if it's the table, but games crashes after completing a level - I'll see if it happens if I disable the pointers before advancing and let you know.
