First things first this only works on the old Bomberman head looking box monitors mostly known as CRT's. (Does not work on modern LCD or OLED monitors. (as far as I know.)

So I will make this as straight forward as I can without any videos or images. But if I do need to make videos because it is not clear enough I will happily do that.

#1. So first things first right click on the Backyard Baseball games name in your library selection.

#2. Click on Properties.

#3. Click on the Installed Files Tab in the new window.

#4. Click on the Browse button.

#5. Right Click on Baseball exe or also known as a application file. (the file that is a picture of a kid in a hat)

#6. click on properties.

#7. In the new window click on the compatibility tab.

#8. Click on Run in 640x 480 screen resolution box and make sure it is checked.

#9. Click apply on the lower right of the window.

#10. go back to your steam library and start the game from there.

If you follow all these steps and on a CRT monitor it will work.
