Debug Dualsystem ROMs?
Is there a way of debugging dualsystem ROMs with “two screens”? “Mesen” doesn’t seem to like Dualsystem ROMs but is there another way?
Re: Debug Dualsystem ROMs?
MAME should work, although its debugger has a learning curve.

Mesen does support it. You need to make sure the rom header is set up properly.
However, when I attempted to use the shared RAM in my game, Mesen crashes. I suspect you might run into the same thing with something like Vs. Tennis or other games that are multiplayer across both screens.

Thanks for the tip!
There are two problems here, Mesen won't load my Mapper99 files so I can't edit it's header. If I manually change the header to something else it loads and I can change it (looking at your example), but Mesen crashes when loading the file afterwars.

There must be more to it, since as you can see, I am loading a Mapper 99 rom in that screenshot. I've attached the ROM if you want to try that out (maybe we have different versions of Mesen).
Assuming this ROM opens fine for you, but your other ROM does not, maybe you could open both in a header editing tool, and see what is different:

Perhaps the ROM you have is misconfigured or uses some feature I am not.

Cool. That attachment worked. I'm using 0.9.9 of Mesen.
