A puzzle game that was only released in Japan.

Debug Menu#

This game feels like Dr. Mario.

Game Genie code 0C2-14F-E6A will start you off in a debug menu allowing some basic features such as CHR viewing, sprite viewing, game mode setup and a sound test.

GAME START#

SATAN

Takes you to a game configuration setup menu where you can adjust parameters and select your Character. Press Start to begin the game with your selected settings.

CHARA DISP#

left View Character Tilesets.

For some reason, the "CHARA NAME" is always empty. However, the ROM contains a full list of corresponding names for all CHR blocks. They are even processed somehow by putting in a RAM buffer, but no code left that actually draws this. List of "CHARA NAME" is after 0x3C869:

 NORMAL ASCII HIGH

Unused Super Game Boy Border#

There is an unused and unreferenced Super Game Boy border that looks like an early version of another border used in the game. For comparison, there are less details in the picture, also a yellow frame is used inside the window not outside of it.

Unused Super Game Boy Sound#

This page or section needs more audio.
There's a whole lotta words here, but not enough audio. Please fix this.
Specifically: Rip the sound.

Located at 0x0353F is the first Super Game Boy sound. Game Genie codes 3F3-10C-5D4 + 353-11C-3BA will play this unused sound during startup.

Unused Text#

At 0x3DB5F, there is unused text for another debug mode screen. It is unknown where it should be displayed, but it has no VDP initialization and just copies text to the VRAM directly.

    WARNING  !!     
                    
                    
                    
 YOU HAVE TO        
           RETURN.  
                    
                    
 (PUSH START        
      TO RETURN)

Also, at 0x5FC40 and 0x63C40 there two identical strings with some mastering tool signature, probably used to draw SGB borders, since both places are at the end of the SGB borders data.
