Tamagotchi Connection

ROM Testing
This tests for any problems within the toy including pixels, ROM and the connection feature. It is accessed by holding 'A', 'B' and 'C' at once while pressing the Reset button.

Debug Mode
To enable the debug mode, remove the battery and disassemble the Tamagotchi so the back circuit board can be accessed. Next to where the battery was, there will be solder jumper JP3 with the name "DEBUG" above it. To activate debug mode, short the two pads of the link using solder or graphite from a pencil.

Debug has two main functions:

Hyperspeed
This makes the character rapidly move about the screen and age. This allows a baby character to grow up to the adult stage within minutes when it would normally take about 4 days. Hyperspeed is activated and deactivated with the 'C' button.

Character selection
This allows the user to choose their character as soon as the egg hatches. Any official character can be chosen and a number of secret characters can also be chosen.

Most secret characters are taken from the "Deka Tamagotchi", a promotional toy featured in a number of Japanese stores in 2004 where the characters could "befriend" normal Tamagotchis, therefore normal Tamagotchis would need data stored on these characters.

The Version 1 has additional secret characters which were later made official on the Version 2. These were likely to have been beta characters.

Connexion
This feature has not been found to be included in the Tamagotchi Connexion (European and Australian release) because of the Connexion's different circuit layout. It is unknown if the feature was removed or relocated to a different part of the circuit without the 'DEBUG' label.

Version 1
Eight of the secret characters are originally from the "Deka Tamagotchi". An additional ten appear to be beta characters, some borrowed from previous Tamagotchi generations.

Version 2
The ten "beta" characters are now official characters, therefore can be obtained without debugging. The eight "Deka Tamagotchi" characters are still accessible through debugging.

Version 3
Nine of the "beta" characters have been completely removed and one is still an official character. The eight "Deka Tamagotchi" characters are still accessible through debugging.

Region Change


The Connection (North America) can be turned into a Connexion (Europe, Australia). To do this, look for solder jumpers JP1 and JP2 towards the left of the back of the circuit board. Short both of them to activate the features mentioned below.

Connexion
Like the Debug feature, this is not included on the Tamagotchi Connexion hardware. It is unknown if there is a way to turn a Connexion into a Connection.

Version 1
This feature will result in:
 * The date system will change to Day/Month instead of Month/Day
 * The word 'Gender' will be replaced with 'Style'
 * The words 'Time Out' will be replaced with 'Punish'
 * The pause feature doesn't work

Version 2 and 3
The only effect this will have is the date system changing to Day/Month instead of Month/Day.
