You would need to replace "Resume" with the name of your highscore
table(if that's all you want to write back), and change "ld b,156" to
however many bytes are in your highscore table.

If your highscore table looked like this:

HighScores:
	.db "1. ----------",0,0,0		;13 bytes
	.db "2. ----------",0,0,0		;13 bytes
	.db "3. ----------",0,0,0		;13 bytes
