Altering flashrom?   Message List  
Reply | Forward Message #258 of 1156 |

Has anyone found if it's possible to alter flash memory outside of the
game file's area by using a direct call (ie, not through the BIOS)? I
recall the method was on one of the development web pages but it didn't
mention if the address limit still applied.
I am wondering if it would be possible to make a savefile editor utility
AS a VMU game so that users who don't have Nexus cards can modify their saves.
