I have official gotten the application to work. Pointers for those who have same trouble as me:
Use the Application BEFORE plugging the NES Mini in. Press Dump Kernel/Patch Kernel/Add Games.. THEN follow instructions on screen.. As soon as the directions disappear, LET GO OF THE RESET BUTTON IMMEDIATELY.. That last part resulted into "broken pipe" a few times.
