Mobile Trainer is a peripheral for the now defunct Mobile GB Adapter for the service Mobile System GB for Game Boy Color and Game Boy Advance  games which made use of online services such as Japanese Crystal. It allowed players to configure their mobile phone data, access the Internet and send email.

Using the Game Genie code 064-C09-E6E or GameShark code  01067DC2, we can skip the menu (if your device/console allows it).

When you get to the title screen, you may try calling address 19:43E9 (offset 643E9) to enter a glitchy debug menu!

This requires a bank switch (write 19 to FF8A and then use a ld (2100), a instruction) first. I don't know of any Game Genie codes that would let you do this, but will post them if I find any.

Sadly, the debug menu does not appear to be that impressive. You can press Start to access its binary to decimal/decimal to binary 
converter in which you enter a value in either decimal or binary and press Start to convert it, but this seems to be about it (at least for now).

Pressing Select or B will bring you to another glitchy menu in which 
Start can be used to put a cursor on something. Pressing B or Select again returns you to the initial connection screen.

The text for this debug menu was documented by divingkataetheweirdo on The Cutting Room Floor. I looked into it the code and found how to access it.
