+ <!-- Notes from Sean
+
+ G10 has a 24LC02, but no 74HC125, and pin 2 isn't connected.
+
+ G10 is very odd; the SEEPROM's SDA is tied high with a 4.7K resistor and connected to pin 4 through a 220 ohm resistor.
+ Pin 4 on the other carts I've looked at is VCC, also connected to pins 21 and 35, but on this one, it isn't.
+ Likewise, SCL is tied low with a 47K resistor and connected to pin 32, which on all the other carts is connected to pins 1 and 44, which are ground.
+
+ e-Kara units, Popira, Taiko de Popira and DDR all of them have pin 4 of the cart connector going to VCC and pin 32 going to ground. So none of them can communicate with the SEEPROM in G10
+
+ Unless Popira 2 is different (unlikely) it doesn't look like the SEEPROM in this cartridge can be used (unfinished design?) -->
