Start in unused Bathroom Level 090-C2A-E6A Entering the Game Boy Game Genie code 090-C2A-E6A or modifying the ROM address 0x50C2 to 09 will start you off in an almost finished Bathroom level. Music from the Dumpster area is played and a custom palette setting is shown. Three enemies will shoot at you, there is a sink with frozen water and a toilet that you can walk on. Accessing the upper-leftmost area is impossible since you cannot jump far enough with a running leap. Exiting from either the left side or from the incomplete collision from the far left will lead you out into the Upper Hallway where the door is closed. Oddly, pressing up at the doorway entrance will display the word ENGAGED.
Super Game Boy SOUND Oddities There are two seperate routines that load two distinct mute flags 80 when pausing the game. Game Genie code ??5-CCF-E68 will set the BGM flag for the first instance, and ??5-D2F-E6C for the second. Do note that setting the second instance will be one value higher (81 is mute). It is also likely that internal Super Game Boy sound effects were planned as with Olympic Summer Games (Game Boy). Game Genie code ??7-33F-E68 will set both A and B sounds because they are both referenced under the same routine.
Load Unused Super Game Boy Programming JUMP Replace loaded PAL_PRI with unused unfinished JUMP Command 70D-70C-E68 Super Game Boy command packet 91 Used to set the SNES program Counter to a specified address. Alternatively, the JUMP can be used to set a new address for the SNES NMI handler, the NMI handler remains unchanged if all bytes 4-6 are zero. 0x8170 shows a JUMP Super Game Boy Packet that is loaded during startup though it does nothing since bytes 4-6 are set to zero. Examples of setting JUMP bit 6 to 18 can be seen in Space Invaders and Nekketsu! Beach Volley dayo Kunio-kun. Setting this command will hang the Super Game Boy BIOS indefinitely if there is no proper programming and call setup routines. ICON_EN Game Boy Game Genie codes 6DD-79C-E60 + 031-A1B-E6A will disable palette and controller settings where they should be, however the SOUND 80800080 will be constantly set. Game Boy Game Genie codes 711-60B-C4D + 031-A1B-E6A (or A0D-70C-E68 + 031-A1B-E6A) will achieve a playable effect, assuming this is what would have been disabled judging by the other Tiertex games that disable functions. SOUND 90D-70C-E68 will replace the loaded PAL_PRI command with the unused SOUND. Set flags with ??1-91B-E6A, ??1-92B-E6A, ??1-93B-E6A, ??1-94B-E6A A single SOUND command can be found in the packet listing, located at 0x8190. Likely a placeholder for internal Super Game Boy sounds, had the reference and call bits been set. PAL_PRI Command C9. when bit 01 is set to 01, palettes are switched back to default when directed to by the game, and since palettes are disabled by the game, this is unnecessary and leftover from a probable early idea to merely have them switch back instead of disabling them as seen in Kirby's Dream Land 2, Donkey Kong (Game Boy), Donkey Kong Land and others. Loaded after PAL_SET with all bits set to 00. Game Genie code 011-81B-E6A will enable this feature.
Super Game Boy Debug Modes (By setting ??C-DEC-E6E you can disable specific Super Game Boy functions that were likely used to test certain features, likely normal Game Boy sound.) ??C-DEC-E6E 00 - No Super Game Boy SOUND commands or palettes will load. Normal Game Boy music will play. 01 - Normal Super Game Boy functions. 02-FF - SOUND command 80800080 will load at startup and whenever the song changes. Likely used to set a specific song for testing. set Super Game Boy Debug Flag 2 BGM Flag ??5-CCF-E68

Fall speed modifier (lower values yield slower falls) ??3-61B-2AA Jump height modifier (This game uses an arbitrary value for determining the jumping height. C0 jumps over the fence exactly, AF is a good height to jump higher, 9D is the maximum height you can safely jump from the ground without dying from hitting the tip of the screen. lower values will yield higher jumping. If you jump too high off the screen you will die.) ??4-47B-C49 Disable enemies and power-ups (This might break some events later in the game, and you will need to jump over the fence using the jump height modifier code.)
