《小川範子》(No・Ri・Ko)是由Alfa System開發、Hudson發行的約會模擬遊戲，於1988年12月4日在PC Engine CD-ROM上市。當時是與《快打旋風/街頭霸王》(Fighting Street)最早期在PC Engine CD-ROM/TurboGrafx-CD推出的兩款遊戲，也是首款將對話語音化的作品。

故事描述於1987年出道的日本青春偶像小川範子（Noriko Okawa）。玩家找到她遺失的火車月票後，為表達感謝，經紀人特別送上演唱會門票並安排兩人的約會。

遊戲中，透過十字鍵移動浮標，按I確認指令，按II取消，同時按R+S即可重新開始。

約會的地點可自由選擇。來到服裝店就可以幫範子挑衣服，還能挑戰一些小遊戲，每次闖關約30分鐘，有不同的選擇路線和結局。遊戲內包含範子的音樂曲及三首單曲，每個影片以動畫方式呈現，是戀愛模擬遊戲的始祖。

秘技：

1.從開機開始到小川範子的標題畫面出現為止，連續按Ⅰ、Ⅱ兩鈕，就會進入測試狀態，按左就會聽到範子說「碰」。

2.在姓名登錄輸入「でもんすとれえしょん」(展示表演)，就可邊看畫面邊聽喜歡的歌曲。總共有四種模式：1. Visual：可以看到所有視覺畫面；2. CD：聆聽所有歌曲；3. PSG：全部的BGM音效；4. 開啟「おしやべり」(瞎聊)模式，範子會說出讚美的話。

3.從範子的房間回來後會出現流星殞落的場景。這時候持續按Ⅰ鈕及Ⅱ直到流星消失，就會看到拍攝場景的三張隱藏畫面。

"Noriko Okawa" (No・Ri・Ko/小川範子) is a dating simulation game developed by Alfa System and published by Hudson, released on December 4, 1988, for the PC Engine CD-ROM. It was one of the earliest games to be launched on the PC Engine CD-ROM/TurboGrafx-CD, alongside "Fighting Street." Moreover, it was the first game to incorporate voice dialogues.

The story revolves around Noriko Okawa, a Japanese idol who debuted in 1987. In the game, players express gratitude after finding Noriko's lost train pass, leading her manager to generously offer concert tickets and arrange a special date.

The gameplay involves using the directional pad to move a cursor, with I for confirmation, II for cancellation, and simultaneous pressing of R+S to restart.

Players can freely choose the date locations, such as a clothing store where they can help Noriko pick out outfits or engage in various mini-games, each taking approximately 30 minutes to complete, with different route choices and endings. The game includes Noriko's music tracks and three singles, presented in animated form, making it a pioneer in the dating simulation genre.

Cheats and secrets include:

1.From the boot-up to Noriko Okawa's title screen, continuously press I and II to enter a testing mode; pressing left will trigger Noriko to say "touch."

2.Enter "でもんすとれえしょん" (exhibition) as the name during registration to watch visuals and listen to favorite songs in four modes: Visual, CD (listen to all songs), PSG (all BGM sound effects), and "おしやべり" (chit-chat) mode where Noriko praises the player.

3.After returning from Noriko's room, a shooting star scene appears. Continuously press I and II until the star disappears to reveal three hidden scenes.

4.When going to Karuizawa with Noriko and wanting to take a photo, press II to lift Noriko's face for a unique perspective.

5.In the later stages at Noriko's house, if you lose in rock-paper-scissors, press II to play again.

6.Play the game without entering any name, and after completion, Noriko will address the player as "君" (you) and introduce characters as "親愛的" (dear).

7.If you don't want to wait on the date and go home, a special event with Noriko will unexpectedly occur.
