I am having some trouble with starting the game.
All the files are unzipped and ready, executing the nw.exe file opens what I believe to be the game. It is, however, a non-stop black screen with the program header "Karryn's Prison - Loading"
I have two tips how you can fix your error
1st tip is close all browsers so goggel Crome, Internet Explorer, Opera and so on.
2nd tip is download RPG Maker VX Ace from the site: "https://www.rpgmakerweb.com/run-time-package" this is the engine where the game runs.
these two things can help.
