After hours of digging and searching I found that these don't do what they say.
Store Base address at
44000 : [XXXXXXXX] = ba
Store Pointer address at
4C000 : [XXXXXXXX] = po
To me that means
44000000 80AABBCC should store the ba at 0x80AABBCC
but what it really does is try to store it at 80AABBCC + 80000000 assuming the ba wasnt changed.
this is exactly the same as:
44010000 80AABBCC would do and of course both will crash the wii.
44010 : [XXXXXXXX+ba] = ba IS THE SAME AS 44000 : [XXXXXXXX] = ba
and the same goes for the po versions 4C000 and 4C010.
