Some final code requests (and screenshots)

Well in that case, use a debugger and set a breakpoint at C2/566E to see if the code is executed when you use step mine.

To be clear, this code is run at the start of a battle, not when you use step mine.

The reason it didn't work is because you're using a 1.1 ROM, and I gave you the code for 1.0. Searching the 1.1 ROM for "E0 44 00 D0 09", the code I quoted appears to start at C2/586E in 1.1.
