Pokonyan! Yume no Daibouken

'Pokonyan! Yume no Daibouken, or Pokonyan! Big Dream Adventure is one of the very few Game Boy games that utilises the SOU_TRN' command giving the game an alternate soundtrack (also plays internal SGB sound effects) when played using a Super Game Boy. SNES objects were also planned to be displayed on the title screen. Pokonyan probably didn't sell too well because the game had a small print run, was aimed exclusively at very young children, and is fairly difficult. Unfortunately, Toho went out of business soon after the release of Pokonyan, and the game was only released in Japan.

Unused World Map Border Setting
There is a routine that sets the Super Game Boy border for the World Map, however the pointer that selects the border is set to so the game does not change the border upon loading the world map. Game Genie code will set the border for the world map to any border in the game.

OBJ_TRN
Code OBJ_TRN Command  - Used to display up to 24 entrees of scrollable 8x8 or 16x16 SNES Objects on the screen comprising a total onscreen palette of 256. Real Bout Special Fatal Fury and Bomberman Quest call OBJ_TRN though neither game loads data into the SNES VRAM. (Mario's Picross and the Japanese version Mario no Picross does not show their title screen logos as an SNES object, rather using the border to overlay the in-game action window. Screensavers for Super Game Boy borders will be disabled (same as ATRC_EN with bit set to ) when OBJ_TRN mode is enabled if fully implemented.

SNES Object Mode
Evidence of plans to use the SNES Object Mode on the title screen exist and unused CHR for the title logo exist, however palette information was not implemented and as a result, proper palette settings are still unknown leaving a guess as to what the title screen objects should look like. Commands are located at:
 * - (CHR_TRN) - Sets Picture attribute tiles to transfer as OBJ tiles.
 * - (CHR_TRN) - Unused OBJ_TRN define setting. Never called or loaded in the code.
 * - (CHR_TRN) - Unused OBJ_TRN define setting. Loaded Twice though never called.
 * - (OBJ_TRN) - Enables OBJ_TRN mode. Loaded twice at  and.
 * - (OBJ_TRN) - Disables OBJ_TRN mode. Loaded once at.
 * - (OBJ_TRN) - Sets OBJ_TRN system palettes 4, 5, and 6 (0-511). Never called or loaded in the code.

The OBJ_TRN enable command is loaded at the title screen along with the other packets for palette and SOUND commands but it is never actually read out from the SNES joypad registers.

Unused Music
An unused jingle can be found in both Game Boy and Super Game Boy soundtracks.

Unused Super Game Boy Jingle
Game Genie codes will play this jingle upon entering the title screen. Based on the bank in which the jingle is stored, it may have been intended for an earlier level complete theme.

Unused Game Boy Jingle
Gameshark code will play this jingle everywhere. Based on the bank in which the jingle is stored, it may have been intended for an earlier level complete theme.

Unused Super Game Boy Commands
Several additional commands exists and were likely used for testing purposes.

SOUND
Several SOUND entrees in the listing are unused or set to. After ID 22 which are garbage commands,, wraps around.

Game Genie code will load any of the SOUND commands upon jumping. The command 'IDs likely used for testing purposes are

The IDs belonging to the nullifyed commands are.

ICON_EN
Located at is an ICON_EN setting that disables both palette and controller selection. Game Genie code will load this command instead.

ATTRC_EN
Normally if OBJ_TRN is used, system border attract mode is disabled. This command might have been added after it was decided not to use OBJ_TRN mode and the SOUND command loaded right after ICON_EN was likely the original place and might have been swapped in place of this command at an unknown time during development. Game Genie codes would restore this function. The bit setting is, disabling all border screensavers.
