Hi
I'm trying to make slot2 digital input / ouput.
I read this page(http://nocash.emubase.de/gbatek.htm#gbacartioportgpio)
,and trying to make it working.
Here is my code.
simple hello world code with output(void) function for setting register.
hardware : attached data lines to all slot2 pins and test with led.
thank you for reading my post.
Happy new year!
