Will it work or should I wait for the remaster?
I'm running win 10 1909 ( Havent had any trouble yet with older games)
If you are asking about the MH Kingpin patch https://www.gog.com/forum/kingpin_life_of_crime/ws_1080p_with_the_listed_mods_patch
then yes it works. Most ppl in the Kingpin community are using it.
It allows custom resolutions, fixes most problems that cause Kingpin not to work, has lots of tweaks and fixes, adds new options to the visuals menu, adds all the current Kingpin online servers to the Gangbang menu etc etc.
It worked great. I have yet to install more SP maps. I will after the main game .
