Bishoujo Senshi Sailor Moon - English and Hidden Features

Bishoujo Senshi Sailor Moon: English and Hidden Features

This patch transforms the original Japanese Game Boy release of Bishoujo Senshi Sailor Moon into an expanded English edition while also restoring hidden developer features and adding several optional cheats.

The dialogue has been translated into British English and reformatted for the Game Boy’s limited text window. The original Japanese title artwork has also been replaced with the classic English Sailor Moon logo.

Main Features

• Complete (British) English dialogue and story text
• Expanded and revised English Charm descriptions
• English introductions for all four stages
• English TAKE A BREAK pause-screen message
• New English title screen with crisp pixel-art credits
• Restored developer Stage Select, originally inaccessible during normal play
• New hidden infinite-health mode
• Cheat-controlled stage-skipping feature
• Additional hidden message added to Stage Select entry 5
• Corrected initialization and player controls when skipping to Queen Beryl
• Original A+B+Select+Start software-reset command retained

New Hidden Controls

Title Screen

• Start — Begin the game normally
• Select — Open the developer Stage Select

Boy/Girl Selection Screen

• A — Confirm the selected difficulty normally
• Select — Enable infinite health and automatically confirm the current selection

While Infinite Health Is Active

• Start — Pause or resume the game
• Select while paused — Skip to the next major exploration or action phase
• Stage skipping is disabled during the final boss

Infinite health prevents ordinary health loss but does not necessarily protect against pits, scripted deaths, or other special game events.

Patching and Compatibility

The BPS patch must be applied to a clean 128 KiB Japanese ROM. It produces an expanded 256 KiB MBC1 Game Boy ROM.

The patched game is compatible with suitable Game Boy emulators and 256 KiB-or-larger MBC1-compatible flash or reproduction cartridges. The original retail cartridge’s 128 KiB mask-ROM chip cannot hold the expanded game without physical chip replacement.
