Hello and happy new year!
A while ago, I've got a "thrashed" Sonic 3 cartridge and with some help I could put it back to work.
So far so good. The cartridge has been played locked with Sonic & Knuckles and saves fine with it.
The problem is that if I play the cartridge alone, it also don't saves but corrupts the old saves too.
This seems really weird!
Would the resistor I used to fix the boot problem be causing some interference with the saves?
If so, what can I do? Put an pull up resistor with the same value or trying to add a buffer on this pin (D7) be the most apropriated solution?
Thanks in advance.
