The Debug program, embedded into most modern Tamagotchi releases, is an operation that tests animations, characters, and events programmed within the Tamagotchi itself. The first Tamagotchi with the Debug program was the Tamagotchi Plus, and all releases, except European releases, have this functionality. The only European release to have debugging is the "Tamagotchi PC Pack" V4.5.
Debugging done manually begins with opening the rear panel of the Tamagotchi and removing the rear of the main shell. The method of debugging varies between versions.
Versions 1, 2, 3 and 4
On the back of the circuit board, near the battery, are two foil semicircles (known as solder jumpers in technical terms) with DEBUG written above. Using a pencil, owners draw a line of graphite between the two half circles to connect them. Another, less commonly used method to connect them is using solder. Upon re-assembling the Tamagotchi and restarting it, all of the immediate effects take place.
The debug function is placed on the front of the circuit near the screen and requires solder and a wire. Two square shaped solder jumpers labelled R11 must be soldered together along with a wire. The wire must also be soldered to a small circle with DEBUG written above.
Debug Removal is a process used to turn off the Debug program and return the Tamagotchi to its formal state. This is done by re-opening the Tamagotchi and erasing the graphite (either via eraser or the end of a flathead screwdriver) or removing the solder depending on what method was used. The effect is not always immediate, and some Tamagotchi pets may jolt into Hyperspeed mode. When the Tamagotchi has not been undebugged, it may stop being debugged for a short period of time.
Hyperspeed, as named by fans, is a process that starts as soon as the debug program begins, and the Tamagotchi moves and operates at breakneck speed. For every real-life second, 15 minutes pass in this mode.
Hyperspeed can be activated by pressing the C button. However, on some Tamagotchi releases, pressing C triggers a C-Click Reaction, meaning it cannot be activated.
Hyperspeed can be deactivated via the C button. On some cases, it may deactivate automatically.
Character Selection is an effect if the owner hatches a new Tamagotchi after debugging. As soon as the baby appears, the owner can press A and scroll through characters programmed into the Tamagotchi, able to gain access to previously unobtainable or difficult to obtain characters.
The following characters can be obtained exclusively through debugging except where noted.
- Three Blocks
- Tsutayatchi (Replaced by a second Nazotchi on Version 3)
- Butterflytchi (Version 1 only, later made available non-debugged in Version 2)
- ChoHimetchi (Version 1 only, later made available non-debugged in Version 2)
- Flowertchi (Version 1 only, later made available non-debugged in Version 2)
- Kaerutchi (Version 1 only, later made available non-debugged in Version 2)
- Marumimitchi (Version 1 only, later made available non-debugged in Version 2)
- Propellertchi (Version 1 only, later made available non-debugged in Version 2)
- Toratchi (Version 1 only, later made available non-debugged in Version 2)
- UFOtchi (Version 1 only, later made available non-debugged in later versions)
- Violetchi (Version 1 only, later made available non-debugged in later versions)
- Whaletchi (Version 1 only, later made available non-debugged in Version 2)
Known Issues Among Releases
Some Tamagotchi releases, though possible to be debugged, have negative side effects when debugged. The Tamagotchi Connection Version 3 and Tamagotchi Connection Version 4, for example, lose PC access (not the V4.5), though it's unknown if the same can be said for the internet-based Japanese releases, Chou Jinsei Enjoi Tamagotchi Plus and Ura Jinsei Enjoy Tamagotchi Plus. The Tamagotchi Connection Version 4 and V4.5 also cannot turn off Hyperspeed.
Although debugging is commonly used by enthusiasts, some claim that debugging is wrong and "removes the realism". Some, when not handling their Tamagotchi carefully during the debugging process, can easily cause permanent damage to their Tamagotchi, including sound loss (sound wiring breaking) or permanently damaging the Tamagotchi's circuitry, making it unusable altogether. However some issues are actually caused by the battery not being placed properly which can be fixed if the Reset Button is pressed. Despite the risk, some users have run with the Debug program activated for years with no problems.
