Hope this is the right place for a quick question on debugger functioning. I'm trying (in vain) to set a watchpoint for a memory region that is not part of the cpu memory map. In my case, I'm debugging the Sega master system. In memory view, you'll find a list of variables, e.g. VDP/:sms_vdp/0/m_reg for the VDPs different registers. But how do I access this memory space in the debugger?

Thank you!
