i tried 8kb, 64 kb it doesnt seem to work on pokemon diamond,
it can saved, but once u tried to load, it goes back to start a new game,
i tested 256kb, i can save, but when it is loading, it turn black screen and stay there for quite long time,
512kb too, the same with 256kb
FRAM 32k, seems that can be saved but when u restart, u will start a new game,
i think all of the save type cant work..
anymore suggestions? when im free i'll try it out.
