This is the last remaining fork of gredguy's Star Rod decomp.

Star Rod

Clover created the original tool. I'm attempting to reverse engineer is. It's used asm hacking, map editing, and dumping games assets.

set breakpoint at 0x0010F292 (current HP) at the first data point in the memory viewer [05] 0A

if you hit an hp block the breakpoint hits! then you're brought into the Commands window where you can reverse engineer the asm function. click step in the command window to walk through the code squence.

command addresses for hp update, each non indedented addresses is a step in the call stack
