From TV Animation One Piece: Maboroshi no Grand Line Boukenhen!

The One Piece series takes on an RPG adventure in the form of more obscure quizzes, and is most notable for being the last official game to be compatible with the Game Boy, Super Game Boy, and Game Boy Color – all at a whopping 4MB!

Debug Menu


GameShark code or Game Genie code  (using the Banpresto logo palette) will start the game in a debug menu. The menu includes a character viewer, cutscene viewer, sound test (music starts at 130), and the ability warp to any point in the game.

Super Game Boy
This was the last official Super Game Boy game ever produced, and includes a custom border, a palette for the Banpresto logo, and a very bland palette for the game all-around.



Unused Super Game Boy Palette


Appearing with the general border and INIT DATA_SND commands, there are two unused palette settings appearing slightly darker than the initial palette. It is unknown why they appear in the main listing instead of the separate palette listing.

Game Genie code (13, 23) will load either unused palettes. Both are located at. 017B6F10424A29000010424A29000000 - PAL01 097B6F10424A29000010424A29000000 - PAL23

Leftover Super Game Boy Commands
One Piece - Maboroshi no Grand Line Boukenhen! is one of the many games that contains a completely unused set of Super Game Boy commands that are likely remnants of a Nintendo tech-demo or dev-kit given to developers to see the many available enhancements in action. Starting at is the full listing. The last DATA_SND entrees are used and are loaded at startup. 01EA4FE003600220013F011F000B0000 - PAL01 09EA4F007C005C00283F05393ADD4E00 - PAL23 11FF7FDA5A9431BF14E001BF02000000 - PAL12 19386B5056883DA0284800393ADD4E00 - ATTR_LIN 2102030901010505020607070E0E0000 - ATTR_BLK 2902AF42000000000000000000000000 - ATTR_CHR 31270600000000000000000000000000 - ATTR_DIV 39000028000000000000005555555555 - ATTR_CHR 41010003000000000000000000000000 - SOUND 49000000000000000000000000000000 - SOU_TRN 510000010002000300C0000000000000 - PAL_SET 59000000000000000000000000000000 - PAL_TRN 61000000000000000000000000000000 - ATRC_EN 69010000000000000000000000000000 - TEST_EN 69000000000000000000000000000000 - TEST_EN 71000000000000000000000000000000 - ICON_EN 7900807E0B0102030405060708090A0B - DATA_SND 8100807F000000000000000000000000 - DATA_TRN 89030000000000000000000000000000 - MASK_EN 9100807F00887F000000000000000000 - JUMP 99020000000000000000000000000000 - CHR_TRN A1000000000000000000000000000000 - PCT_TRN A9000000000000000000000000000000 - ATTR_TRN B1000000000000000000000000000000 - MASK_EN B9010000000000000000000000000000 - MASK_EN C1010000000000000000000000000000 - OBJ_TRN 510500060007000800C1000000000000 - PAL_TRN 41000000010000000000000000000000 - SOUND 99000000000000000000000000000000 - CHR_TRN B9000000000000000000000000000000 - MASK_EN 21010300000013110000000000000000 - PAL 89030000000000000000000000000000 - MLT_REQ 41090000000000000000000000000000 - SOUND 41120000000000000000000000000000 - SOUND 41250000000000000000000000000000 - SOUND 41250001000000000000000000000000 - SOUND 41160002000000000000000000000000 - SOUND 41070000000000000000000000000000 - SOUND 41020000000000000000000000000000 - SOUND 791B08000BEAEAEAEAEAA901CD4F0CD0 - DATA_SND 792608000B39CD480CD034A5C9C980D0 - DATA_SND 793108000B0CA5CAC97ED006A5CBC97E - DATA_SND 793C08000BF012A5C9C9C8D01CA5CAC9 - DATA_SND 794708000BC4D016A5CBC905D010A228 - DATA_SND 795208000BA9E79F01C07EE8E8E8E8E0 - DATA_SND 795D0800048CD0F46000000000000000 - DATA_SND 791008000B4C2008EAEAEAEAEA60EAEA - DATA_SND
