The first game in the series is particularly notable for its "bomb" feature, where neglected, infrequently-dated girls would eventually become angry and gossip to their friends, severely reducing love meters across the board. In the middle of the game, when the number of known girls was high, these "bombs" became the primary concern of the player, forcing careful planning and strategies like round-robin dating. Although the feature was still present in the later games, it was considerably reduced in importance and the difficulty in avoiding it.
Tokimeki Memorial was first released for the PC Engine on May 27, 1994. It was remade as Tokimeki Memorial: Forever With You on the PlayStation (1995), Sega Saturn (1996) and PC (1997) with a new opening video, improved graphics and sound, and new minigames.
In 1996, it was ported to the Super Famicom as Tokimeki Memorial: Densetsu no Ki no Shita de, and although drastically reduced in graphic and sound quality (the only voice clips were available during loading), included an exclusive CD with a radio drama and new arrangement of the ending theme, "Futari no Toki", this time sung by the majority of the girls, instead of just Shiori Fujisaki (the heroine of the first game).
In 1999 the game was ported again to the Game Boy Color in two versions, Tokimeki Memorial Sports Version: Kotei no Photograph and Tokimeki Memorial Culture Version: Komorebi no Melody, dividing 10 of the characters between the two games and adding three new winnable characters, Patricia McGrath, Naomi Munakata, and Kyoko Izumi. The Game Boy Color versions also featured a Beatmania mini-game, compatibility with the Super Game Boy, a screen saver mode, and a two-player versus minigame.
In 2004, the game was ported to mobile phones in Japan, and in 2006, was ported to the PlayStation Portable portable system, which is virtually identical to the PlayStation version. In 2009, the PlayStation version of Tokimeki Memorial was released in Japan on the PlayStation Store to celebrate the franchise's 15th anniversary.

- Often seen around school usually with other girls, Yoshio provides the player with information on the available girls, including their phone numbers, blood type, and various things they like earning him the nickname "Info Otaku". Yoshio's phone number is one of the three phone numbers the player receives in the beginning of the game. If certain conditions are met, Yoshio will become a rival to the player at the end of the third year, attempting to win the heart of one of the girls. The girl he ends up with are limited only to those the player has met and will depend on the player's own success with the girl he has chosen; however, he does not directly fight for any girl the player has chosen. In the spin-off gameTokimeki no Houkago ~Ne Quiz Shiyo~, Yoshio is a winnable character although the player does not actually end up with him; instead, the player and Yoshio make a pact to both find girlfriends. This makes him the only male character (prior to Tokimeki Memorial Girl's Side, in which the main objective to end up with are male characters) where the main character can end up with him.
