before activating debug script,
Check out wiki page : https://wiki.cheatengine.org/index.php?title=Mono,
alternatively should be "[$Lua] Activate Mono Features" script which activates features for you.
PS. Game can only run only in x64 bit environment, double-checked that. (If release & update for 32 bit os would come, I will try to update this)
Used this in the past, so I can confidently say I didn't miss anything stupid in trying to open it now. Attached game, activated mono features, opened the cheat table, and then opened the side menu. I remember it working before, and sometimes you'd even have to go switch from Main Sim to either the dino or space one, or vice versa, but nothing worked for getting the menu to open. They've been doing some pretty significant overhauls of the in game menus lately, so that's probably why.
Hopefully this gets fixed! They added options that costs you hundreds and hundreds of Darwinium cubes, so, combined with how many cubes I've used in the past, you'd easily have to buy the $70 worth of cubes to get most things in the game. Even then, I think you could burn through them quickly. Definitely need this table to work now more than ever!
So, script timer keeps on spinning?
While In Primary simulation ( actually it doesn't matter in what simulation you are in ) :
...While script activation timer is running press once menu button (or ESC key) and wait for a while, once you hear beep from cheat engine then re-press pause button or ESC menu. ( in short, why : mono-2.0-bdwgc.mono_breakpoint_clean_code ).
If you still have issues regardless after that :
