MSX Bunsetsu Henkan Jisyo (FS-SR022)

What is MSX Bunsetsu Henkan Jisyo (FS-SR022)?

Compiled by the Retro Games Online Editorial Team · Updated June 28, 2026

MSX Bunsetsu Henkan Jisyo (FS-SR022) isn't a game at all - it's a utility cartridge for the MSX 1 home computer. Released in Japan during the early 1980s, this software served as a Japanese input method editor (IME) specifically designed for word processing. Bunsetsu henkan means 'phrase conversion', and the jisyo (dictionary) part refers to the built-in kanji dictionary. It was sold by an unknown publisher, likely a Japanese software house, and represents one of the earliest attempts to bring practical Japanese text input to a consumer computer.

The player loads the cartridge and uses it alongside a compatible word processor or terminal program. The core function is typing Japanese text phonetically in hiragana and then converting it to kanji by pressing a key. The software splits sentences into bunsetsu (phrases) and suggests correct kanji mappings from its dictionary. Users navigate through conversion candidates using the keyboard and confirm selections. There is no score, no levels, and no end - it's purely a productivity tool for composing documents in Japanese.

Today, MSX Bunsetsu Henkan Jisyo is a niche curiosity for retro computing enthusiasts and linguists. It offers a glimpse into how Japanese users managed text input before modern IMEs became standard. Compared to later MSX word processors like SANYO's or Sony's, this cartridge is primitive but historically significant. If you're interested in the evolution of digital language tools, it's worth loading up in an emulator just to see the workflow. Just don't expect any gameplay - this is a dictionary, not a dungeon.

How to Play MSX Bunsetsu Henkan Jisyo (FS-SR022) Online

When you first boot the cartridge, you'll see a Japanese menu. Select the option to start the conversion engine - it will load the dictionary into memory. After that, switch to your word processor or a BASIC program that accepts keyboard input. Type in hiragana text using the standard Japanese keyboard layout (requires external knowledge). To trigger conversion, press the B button (S key) - the software will break the sentence into phrases and show candidate kanji. Use the arrow keys to cycle through candidates and the A button (X key) to confirm the choice. The selected kanji will replace the hiragana in your text. The V key (Select) may bring up additional submenus. Since the entire interface is in Japanese, familiarity with the language is essential. No game-like goals exist; just practice composing sentences.
