I am doing research on TecToy Gear Gear releases. From the serial number we can extrapolate print count, reissues, release ordering among other things. Because the print count appears to be very narrow it may be even easier to good estimate using the German Tank Problem formula (https://www.smspower.org/forums/16075)

If you own some TecToy Game Gear games, could you help sending me your product number? (privately, by PM)

The number starts with 063 followed by 6 digits.

You can find them on the back of the manual OR inside the cart shell. Obviously easier to get from the manual. Maybe the simpler is to take a picture of the number next to the front of the cartridge so it's easy to identify them and I can enter the numbers into our database.

Your help would be very useful there!

Here's how the database is going to look like:

But we expect to see reprints in there and therefore games are different positions.

serial number from manual.jpg (103.92 KB)

serial number from inside cartridge shell.jpg (95.5 KB)

list wip.png (37.57 KB)

Gathered 129 data point so far (average a little <2 per game), the more we get the better data we can compute. Thanks in particular to Stan for his help so far!

Which ones are you missing? You can check the manuals in here

Hope it helps.

We need as many samples as possible for each game for this to be useful.
Will look, thank you!
