Bandai released (essentially) a barcode-reader late in the Famicom's life which had the usual array of Bandai anime/manga licenses.

Debug Menu

This is, oddly, the only game in the entire Datach series to retain a debug menu. Game Genie LAOXGAPP will let you access it by selecting "FACTORY" from the title menu.

The debug screen includes a sound test, accessed by pressing Select. You can also build your custom Robot and exit back to the title screen.

Password Screen

Game Genie code IPOXGAPO will replace the "FACTORY" menu option with one that will take you to this screen. The password needed for this screen contains the complete data set for a robot, including the counters of rounds it won on the different difficulty levels. This password screen is completely unused and is not accessible inside the regular game without hacking.

However, there is an secret Easter Egg in this game. If you scan the product code from the official box for this game (4938182860036 or 4938182860050) you'll see a picture above. It contains a 15-digit "secret" NUMBER. This number is what appears to be exactly that password for an unused password screen.

Possible Scrapped Password Feature

While other 5 Datach games support standard EAN-8 and EAN-13 barcodes, and the Crayon Shinchan game does not scan barcode at all, this game does support barcodes, but other than the code of official box, it does not recognize other standard barcodes, only some of the cards that come with the game package. This feature is only used in the "1P VS COM" function where you can fight against some pre-build robots.

Each of those cards contain two barcodes, which can be used in a specified order to input the data of the robot on the card. However, these barcodes are not in standard format.

Judging from the behavior of other Datach games, this game may have planned to use password system to save robot data, so that one can play with their friends (like what happened in the second Dragon Ball Z game). However in the final game, the saving feature is done by the EEPROM chips in the cartridge and the Datach device. This may also explain that this game lacks an "examine" feature seen in other Datach games, whose function is to check the outcome of any barcode from other goods, like a dictionary or some snacks.
