well there are lot of cheat like
40690 89391 (gives a play house)
52815 99088 (gives a Slide)
BBCA CCCA= Pen= 15,000gp (found in US V4 instruction sheet)
2. ACAB ACAC= Steak= 1,400gp
3. BAAB ACBA= !! (clone)= 14,000gp
4. CCBA AABB= Honey (love potion)= 7,000gp
5. CAAA BACB= CD3= 0gp
~The last code you enter will not give you what the code is for! Instead, it will give you a RARE CELL PHONE. If you would still like to get the last item from the last code, you will have to re-enter the code and buy it. I recommend entering the code for "CD3" last because it is free!
How to enter shop codes? Quoting from the V4 instruction sheet:
Did you find a secret code?
At the shop counter screen, press (A).
Then, press (A) quickly three times. When
the shop owner's face appears surprised, punch in
the secret code to reveal a new item.
[Note: A = left button, B = middle button, C = right button]
The list of Cell Phone numbers we've found so far:
AABA CCBB = Parent *
CCAC BCBA = Grandparent *
AACC CABA = Preschool Teacher
ACCB CAAB = Turtle Teacher
CBBC BABB = Flower Teacher
BBAC CAAB = Canvas Teacher
BABC AAAB = Tama King
* Notes:
(1) Your tama character must be on generation 2 or above in order for the parent phone number to work.
(2) Your tama character must be on generation 3 or above in order for the grandparent phone number to work.
How to use the Cell Phone
(1) you have to do this on a V4.
(2) you have to have a cell phone. If you don't already have the cell phone, read this topic and get the cell phone: V4 Codes, All 5 Shop Codes for V4
(3) your character must be an adult (or older).
(4) find the cell phone in your items list and select it. The cell phone will appear on the screen next to your Tamagotchi character with three circles in a row above it. These circles correspond to the A (left), B (middle) and C (right) buttons on your Tamagotchi.
(5) Enter the cell phone number by pressing the A, B, or C buttons in the order shown for the cell phone number you want to dial. After the last digit has been entered, the call will go through, and you will see the person you are dialing appear on your screen. She (or he) will then have a brief conversation with your Tamagotchi character.
