Pokémon Diamond and Jade are bootleg hacks of Keitai Denjū Terefangu (Japanese: 携帯電獣テレファング, lit. Mobile Cellular Beast Telefang). Pokémon Diamond, not to be confused with the legitimate Pokémon Diamond for the DS, was hacked from the Power Version, and Pokémon Jade was hacked from the Speed Version.

These bootlegs are best known for their extremely poor translation, one of their best Engrish phrases is,"Well, have you been eating curry?" Some of the more infamous lines of Engrish are "Some points of 5 lost!", "For the clever opponent, Injure increase!!" and "In severe illness!", among many others. There is also profanity in the games. Many characters and Denjuu (electric monsters) have had their names changed. Some of them are slight changes: for example, one Denjuu called Crypto is called Kuribute in the bootleg. Others are changed completely and inexplicably: for example, the Denjuu Easy Dog becomes Hat, Chameraid becomes Icecream, and Funmachine becomes Game Boy; similarly, the character Kai is interchangably called Boundary, Ken, and Kate.

It also has numerous glitches, the most serious being an inability to load its own save data. Other glitches include crashing after the Game Over screen, and crashing after dialing numbers of secret Denjuu.

Copies of Pokémon Diamond and Jade were once easily available on auction sites like eBay, but have since been banned. Nevertheless, copies spring up from time to time. There is a two in 1 version, featuring both Pokémon Diamond and Jade.

Bugs and glitchesEdit

This bootleg contains a rather incredible number of severe bugs, adding to its widespread infamy.

  • The game would not load a save on some carts. Depending on the emulator/ROM/cartridge, selecting "Contin[ue]" when a saved game is present will cause the game to either freeze or act as if there is no saved game. The data is saved properly, and is valid, but the bootleg is simply unable to load its own SRAM data properly. Via emulation, one can load a save file from Diamond in Power; it will work correctly, but the nicknames will be glitched.
    • In the case of the cartridge, this can be fixed by unscrewing the back, and carefully replacing the CR2032 battery. This method is very simple with the original Game Boy cartridge version that says "GAME" at the top, as it has a Philips screw and a slot for the battery to easily slide in.
  • Dialing secret numbers causes the game to crash, thus making it impossible to obtain secret Denjuu without cheat codes.
  • Selecting "Prop" when there are no items causes the game to crash.
  • Pressing A+B+Select+Start simultaneously causes the game to crash. On most Game Boy games (not just Telefang), this produces a soft reset. The reset routine is implemented by the games themselves; given that it crashes here, the routine was likely damaged in the process of creating the bootleg.
  • Pressing Start after the Game Over screen causes the game to crash.
  • Rapidly pressing B in the phone menu screen sometimes causes the game to crash.
  • The player cannot input a name for the protagonist, who is officially known as "Shigeki"; the latter is automatically named "Bek".
  • Denjuu cannot be nicknamed manually; they are auto-nicknamed, using the 6-character limit that the original already had. Additionally, the Lampgela obtained in the game is nicknamed "o".
  • The color palette is glitched in the introduction.
  • When attempting to create custom tunes, screeching noises are heard, rendering the feature unusable.
  • On Ion Island, the door sometimes locks after beating Gypsophi, due to a glitch.
  • On some carts, vases can not be picked up after you reload a saved game. However, considering that some carts can not load save data, this glitch may not even matter.
  • When playing in monochrome mode, the title screen is invisible until the Start button is pressed, at which point it darkens and becomes visible.
  • When playing in monochrome mode, the background around the letters in the phone menu screen are darker than they should be.
  • The game's clock does not function the way it should, as is evident in an emulator. When the emulator is paused, sped up, or slowed down, the clock will pause/speed up/slow down as well. In the original version, the clock runs at a constant speed (real time) no matter what. In the bootleg, a second in the game passes after every 50 frames instead of 60, making the clock run 20% faster than normal. This is due to the original Telefang using an actual RTC device in the cartridge. Said RTC device is left out of the bootleg carts to save money.

Related BootlegsEdit

  • There are also Chinese versions of Pokémon Diamond and Jade. Due to the similarities in dialogue between the Engrish and Chinese versions, it is likely that the translation of the Engrish version was based off the Chinese translation.
  • There is an NES port made by Waixing. The NES port was made from scratch and poorly follows the original. The battle mechanics are nothing like the original, and none of the music in the NES port is from the GBC version. It also has Pokémon from Ruby/Sapphire, such as Mightyena, Zigzagoon, and Marshtomp, dating this pirated game to 2002 or later. The only thing that is remotely intact is the basic plot.
  • There are Chinese versions of Keitai Denjū Telefang 2. Not surprisingly, the Power Version's bootleg is called "Pokémon Diamond 2," and the Speed Version's bootleg is called "Pokémon Jade 2." Diamond 2's title screen has a picture of Arcanine and a couple of Pokémon characters, and three diamonds on the bottom, very similar to the three diamonds in the original Diamond's title screen. Diamond 2 crashes after the menu screen and is completely unplayable (if emulating, a save state from the authentic Power 2 may be used to bypass the crash.) Jade 2's title screen has Dragon from "Shrek" cartoon, with Pokémon characters, and a jade on the bottom, very similar to the jade in the original Jade's box art (which suggests that these are the same pirates). Jade 2 does not crash after the title screen.
  • There is also an Engrish bootleg of Keitai Denjū Telefang 2, called Pokémon Ruby (has nothing to do with the real one). The title screen is similar to the Chinese version, but with Groudon instead of Arcanine or Charizard, and the text saying "Pocket Monster Ruby". Due to the similarities, it is suggested that these have the same origin. The Denjuu names are very odd, even when compared to Keitai Denjū Telefang's names. For example, Rex is called Leku and Doon is called Dorin.
  • Another version titled 口袋妖怪大集合 (Kǒudài yāoguài dà jíhé [Large Pokémon Collection]) exists that is the original Japanese verson of Telefang Speed, but all monsters in battle and on the map are replaced with Pokémon. Interestingly, all of the monster names were replaced with the appropriate Japanese name of the Pokémon in its place.


  • Both Jade and Diamond were featured on Jontron's Bootleg Pokemon Games video.
