Battle command pointers and general question

Har har, found me a pointer... I think.

C1/7C14 is the line that makes the jump to the Row command from battle menu selection (think I said that right). If you redirect it to the Item command line, 5769 instead of 5631, it will open the item selection menu then allow you to select, target, and prepare to use the item.

Then it comes to a grinding halt and crash. From my playing in C2, and rewriting the Row command section to reroute over to Item (at the time I thought was just the animation portion of it) everything to do with actually using the item selected from C1 seems to be handled in C2.

What I still can't figure out is how, or where, it links from C1 selection to C2 execution... apparently it is not sent over from the Item command section of C1 though.

C1 and C2 are the banks in the rom that handle things during battle. Banks D0 and D1 are also handled with battle events and the like.

C1 handles the size of the menus, as well as the display of some ability names (For example, Magitek, Magic and Tools). Bank C2 is responsible for the actual code of the ability, so you need to go to C2 as well and change the pointers too.
