El disco
It was the third game compatible with the Disk Fax network of the Disk System, and uses a blue floppy disk instead of the regular yellow disk. In 1987 Square wanted to make a Disk Fax adventure game, and Nintendo suggested that the game include an idol, as it would interest players. Though most compatible games used the Disk Fax network to upload high scores or time trials onto the official rankings system, "Nakayama Miho no Tokimeki High School" was the only game where players used the network to register that they had completed the game to receive prizes. The game also contained a phone number which players could call to hear hints concerning the gameplay or listen to a personal message voiced by Miho Nakayama herself. This phone service ended shortly after the release of the game, and the messages and hints are displayed in text form in subsequent versions of the game. The Disk Fax service was used for a contest from December 19, 1987 to February 29, 1988 in which 8000 winners received an autographed phonecard (for those who finished the game with the "normal" ending) and 8000 received a special VHS tape (for those who finished with the "best" ending.)
