This is a harder to find basketball game published in 1990 by Virgin Mastertronic. The disk does not have any copy protection, but after the boot up screen the program goes to the “User Verification Sequence” screen see the image below.
I could find a list of codes online, BUT it is not complete, it only contains about 1/2 the codes used in this program.
Again thanks to: Craig A. Ernster we now have a complete list of codes used. Download the PDF HERE:MAGIC MVP Johnson Sheet
