Pocket Monster is a bootleg Pokémon game that was hacked to make the Tarepanda-themed Panda World, which was also hacked to make the much less well known Super Popo's Adventure.

Unused Audio

To do:
Unused sounds. [1]

Pocket Monster

This song is used in some of Super PoPo's Adventure's levels and on the title screen in Panda World.

This song is used in some of Super PoPo's Adventure and Panda World's levels.

Unused Graphics


A hexadecimal font, unused in all versions of the game.

Super PoPo's Adventure

Super PoPo's Adventure-pushstartmockup.png

Super PoPo's Adventure-teletubbies.png
A Teletubbies logo, stored with the title screen graphics. It was likely removed to avoid legal trouble from the BBC.

Super PoPo's Adventure-push.png
Text reading "PUSH". This is stored next to the "START" text displayed on the title screen, and was likely intended to display alongside it. This can be seen in the mockup to the right.

an unused graphic of Po's mouth.

Bizarrely, Super PoPo's Adventure contains leftover graphics from Tengen's NES version of Tetris! These appear at the very end of the CHR data, at 038010 and 039010 respectively. This is likely a remnant of a pirate multicart, since the font from this game was often used for multicart menus.

Pocket Monster

In-Game Fixed
Pocket Monster (NES)-pikachuerroringame.png Pocket Monster (NES)-pikachuerrorfixed.png

Due to a programming oversight, one of the frames of Pikachu dancing on the ending screen never displays one of the tiles on his arm.

Used Unused
Pocket Monster (NES)-overused.png Pocket Monster (NES)-overunused.png

An unused duplicate of the word "OVER" from the game over screen. It is positioned differently and takes up 8x3 tiles instead of 8x2.

Used Unused
Pocket Monster (NES)-2bottomused.png Pocket Monster (NES)-2bottomunused.png

An unused duplicate of the bottom of the two graphics from the continue screen with a few erroneous pixels on the bottom.

Unused Objects

Pocket Monster

Pocket Monster (NES)-tablelandplatforms.png

A couple of unused platforms, stored with the graphics for the Tableland levels. If added into a level layout with a tile editor, they will behave as ordinary platforms.

Leftover Palette


The palette used for the Tarepandas on Panda World's title screen can be found at 0x2DB34 in Pocket Monster, which proves that Pocket Monster is a hack of Panda World.

Leftover Multicart Code

Pocket Monster (NES)-menu.png Pocket Monster (NES)-menu1.png
The Pocket Monster ROM contains complete and working code and graphics for the menu from the multicart where it was ripped from. It can be re-enabled with Game Genie codes PENNKYAK ENNNSYNN.

The menu is coded to work with a special multicart memory mapper, number 45 in iNES format. So, if you run this menu with the regular mapper 4, you'll see the wrong CHR data. To correct the mapper, use Game Genie codes AXSLXLAA ZXSLULZA GXSLKLGA as well. This still will not fix the font in the menu itself, which needs additional hacking.

The best way to see it fully working is to set the ROM's mapper to number 45 (both pictures above are taken from a ROM with mapper 45).

Pocket Monster (NES)-menu2.png
The menu is coded to support 2 different numbers of games: 300 in 1 and 800 in 1. It checks for some data in the ROM and then sets the corresponding game number. To switch to 800 in 1, freeze memory location $0024 to 01 when switching from the controller menu to the game menu.

Unused Text

Part of an automated program disassembly can be found near the end of PRG bank #8 in the Pocket Monster ROM, from 0x1FA10-0x20009.

Debug Mode

A debug mode is automatically enabled in Pocket Monster when pausing the game. Select skips a level, and the D-Pad lets you move anywhere.

The debug mode is partially accessible in other versions. Pause and press Select, Up, Up, Down, Down, Left, Left, Right, Right, A, A, B, B (for Panda World) or Select, A, B, A, A, B, B, A, A, A, B, B, B (for Super PoPo's Adventure) to skip to the next level. It's unknown if the free movement mode can be triggered in Panda World.

Version Differences


  • Each version of the game has completely different levels and completely different graphics.
  • Super PoPo's Adventure is the only version that has any swimming levels.
  • Super PoPo's Adventure is the only version that has a unique gameplay mechanic: one of the Teletubbies will ask you to find them an item, and in order to complete the level, you need to collect 1-6 puzzle pieces which are part of a six-piece picture of that item.
  • Pocket Monster removes the projectile attack found in Super PoPo's Adventure and Panda World and replaces it with an electric shock attack that kills all the enemies currently on-screen. It also moves the attack meter from the upper-right corner to the bottom-right corner.
  • Pocket Monster reduces the amount of health at the start of the game from 4 to 3.
  • Super PoPo's Adventure waits 5 seconds before the demo starts, Panda World waits for 16 seconds, and Pocket Monster removes the demo altogether.
  • The debug mode is disabled by default in all versions except Pocket Monster. The level skip can be activated with a cheat code in Panda World.
  • In Super Pocket Monster, an undumped hack of Pocket Monster, the collision detection is broken and Pikachu falls through the ground at the start of the first level, making the game completely unplayable.

Title Screen

Super PoPo's Adventure Panda World Pocket Monster
I'm pretty sure it's just Po. Definitely-Not-Tarepanda World. I wouldn't really call Pikachu a monster.

The title screens are very different between each version. Both Pocket Monster and Super PoPo's Adventure use the same song, with Panda World using a different one.

New World Screen

Super PoPo's Adventure Panda World Pocket Monster
Laa-Laa doesn't know how to properly use the second-person. Is that Tarepanda floating? I'm pretty sure that's not a word.

The new world screen is also completely different in each game. Pocket Monster gives its worlds names instead of numbers. Again, Panda World uses a different song.


Super PoPo's Adventure Panda World Pocket Monster
What's so funny? You win! Have a pile of pandas. I'm pretty sure Pikachu isn't supposed to be that dark.

As expected, the ending screens are different in each game. Super PoPo's Adventure requires you to press a button to return to the title screen, unlike both of its hacks, which automatically go to the title screen after a while. This is also the only place in Super PoPo's Adventure where the Teletubbies name is used.
