I am putting these games back together, and I discovered a factory test for doraemon. If pin 35 is grounded (pulled high) at power-up it will go through a display and audio test. There's a pad connected to the pin but it doesn't go anywhere, so it looked highly suspicious. turned out I was right.
That's awesome, thanks hap for adding that to mess too... Now I may have to install a little switch under the 'Open' button or something. 'Mod' my handhelds...
I wonder if the other two in the series do that as well... You'll be getting those soon...
