Demul queries, and arcade over console rom?

[Shinobis Shinpads]

Hi guys,

Just had some quick questions over Demul. I currently have a full cabinet set up on XP. I also have some of my consoles set up via a basic front end with mixed results. My dreamcast set up runs pretty well, although I’m currently using Nulldc for my dreamcast and I’m reading more and more about Demul and wondering if I should change. My main reason for doing so is for stuff like HOTD 2 as I can’t set up my aimtrak guns (I actually have a huge CRT screen for my original dreamcast set up but it blew a while back so I’m desperate to play again!). I guess my questions relate to whether Demul is relatively easy to set up and would anyone generally recommend it over NullDC

Also, from my understanding NullDC emulates Dreamcast and the original arcade roms, so which would you recommend when setting up and how would I know which is which?
