Ty Dorian for relaying my message.
Here's a better explanation
You can't step thru the entire code cuz it scans all of mem80 so it would take literally days to step thru.
So after ur shared item code address BP. Just step once. You are at the codes subroutine. Then u need to set a second BP
The second BP you set is for 'the_loop' (2nd loop listed) of the NoSSL source. Right after the Li r3, 0
After u set the 2nd BP, resume emulation. The game will then stop at the 2nd BP. Now u can finally do normal step by stepping.
