Is your Nintendo Gameboy Tetris cartridge original?
Here are photos my authentic Tetris game cart.
Update November 2023
I have a new model which has been stamped 23A
23A version has an actual IC rather than the blob chip
The main IC is labelled
DMG-TRA-1
SHARP
JAPAN A0
9047 D
On the 23A version the circuit board is marked with..
DMG-AAA-03
This is first copy of Tetris stamped 22A
The front of the board has the words:
U1 PRG
LR0G150
DMG-TRA-1
92092
It contains a blob chip, a small capacitor C1 103, and an unpopulated space for capacitor C2 100uF+
There is also VDD 1 which signifies which is pin 1 (voltage), pin 32 and GND
The back of the board has no noticeable features.
Finally the front of the cart has Nintendo GAMEBOYTM logo embolded on the plastic.
The sticker has the words DMG-TR-UKV, MADE IN JAPAN. The TETRIS logo, ORIGINAL, GAME LINK, GAME PAK logo.
Beneath these are Nintendo and an Original Nintendo Seal of Quality badge. The right side has THIS SIDE OUT.
Another feature of the sticker is the letters 22A marked just above the seal of quality logo, which is almost impossible to see on the photo.
