I saw that 960 was greater than 900, but how would I change the resolution of it if I can't open the program? I am not used to working with program files (except for Minecraft lol) so I am not too sure how to change the resolution by files.
First find out the location of your NullpoMino main folder. If you use a shortcut, then right-click on it and choose properties and you should see the location. Then go to the NullpoMino main folder, and go further into the following subfolder: config -> setting. There you should see a file called slick.cfg. Open it with a text editor (e.g. right-click -> edit) and edit the line:
option.screenheight=...
Then save the file in the text editor. If you can't modify the file, then move it to the desktop, and use the text editor there, and move the file back to its original location after saving.
