replay breakpoints
 
When I set a breakpoint with Action Replay 3.xx (all versions) it doesn't actrivate

When I set same breakpoint with winuae's debugger it activates, so is the replay faulty or emulation?

Any ideas?

Your question is faulty :)

I guess you mean normal AR3 instruction breakpoints, they do work but note that they only work in ram and they can be overwritten (if code is self-modifying etc..)

Okay here is what I am trying to do

Captive loads its mapgen to a certain location then naturally jumps to that location to execute

now I cannot find the jump (I guess it's using registers and stuff) so I figured i'd breakpoint the location it starts and then hopefully it'd jump in there

I tried using the debugger but I need the emulation to pause when returning to winuiae so I can activate the debugger and single step thru (I prefer action replay to debugger for some reason!)

Pause won't help because while paused winuae won't pass any events to emulated side.

Possible solution: use built-in debugger breakpoint normally, when it breaks, use H or HH commands to check last few instructions until you find better breakpoint location. (that is not unpacked/loaded from disk)

is it possible to pause emulation but maybe still read instructions, so I can just go straight into replay when unpaused

A lame solution bippy is to activate AR while the code is still being loaded/decrunched but the start of it is already there. If you breakpoint the address now it should then fire AR when it is run.
