You understood correctly. Now jumps and even more so the conditional
branches are sort of the ugly part of the whole thing. The easiest
method is probably inserting a branch at the jump's destination address
or in case of a branch at the branch target and the instruction following
it's delay slot. So that's a lot of inserting and removing of
breakpoints ...
