Mobile Trainer

Mobile Trainer
Also known as: Mobile Starter Cartridge (original name) Developers: Mobile21, MissingLink Publisher: Nintendo Platform: Game Boy Color Released in JP: January 27, 2001 This game has a hidden developer message. This game has hidden development-related text. This game has debugging material. This game has a hidden sound test. This game has a notes page

This game is defunct. Do note the game no longer works at all without modifications. This is most likely due to the game's servers being shut down. As a result, further official developments with the game are unlikely to happen.

To do: It may be worth adding the hidden Pokémon graphics as they could be unused.

The Mobile Trainer was used along with a peripheral that allowed Game Boy Colors to connect to cell phones, allowing players to communicate with each other wirelessly. However, much of its target audience was unable to use it (without parental permission), multiple cables were required for different phones, and not many games used it extensively. As a result, it was shut down in December 2002.

Debug Mode

Use the Game Genie code 190-05B-7FF to start the game in the Debug Mode (no mobile link device needed).

Here you may toggle on or off some internal debug flags. There are 8-bit value and 8 debug flags to toggle. You may choose which flags to toggle either in decimal or binary representations. Pressing Start will toggle between decimal and binary modes.

In both modes, press Left / Right to select the digit to edit. Press A to change this digit.

In the decimal edit mode there are 5 digits, but only 3 of them are editable. If you select two other digits, the A button will reset the number to zero.

Press Select or B to exit this menu and return to the normal game.
