Hello. I'm making an online form for entering data about DMG Gameboys that you own. The goal is to figure out the connection between serial numbers, circuit board revisions, CPU revisions and manufacturing date. Before I'm releasing this form, I would like to collect some preliminary data to make the form as efficient as possible. (I want to try to make simple choices and radio buttons/checkboxes as far as possible.)
I'd like to know which kinds of Nintendo Hotline stickers there are. I.e. local variations for different countries, phone numbers, different designs etc.
I'd like to know which kinds of serial number stickers there are. Variants I personally own:
GM + 7 digit number
G + 8 digit code
Barcode + G + 8 + 1 digit (last digit is marked in gray and probably a checksum digit)
Are there others?
"Made in" locations engraved in the plastic on the back of the unit. I personally own units marked made in China and Japan. Are there other locations?
QUESTIONS FOR MODDERS:
1) Would you be willing to take part in this for units that you're modding?
2) Do you often mix up parts of DMGs you sell? This is valuable statistical information when users you've sold units to enter data about their unit.
It would also be interesting to know how many of you would be willing to open up you DMGs just for collecting data for science.
I will show a preview of the form soon.
