I will be honest. HOD ( I think I wrote this somewhere else ) was literally this arcade you saw when you went to the movies with your family, or whatever during "Killer Instinct II" only in arcades timeline. That and "Battle Arena Toshegoden" ( whatever ), and of course Tekken II.
It was an amazing time, you went to see Jurasic Park ( when that was a thing ) and could also play this badass game inside a mini-truck thingy, with multiple displays to shoot from or whatever the setup was.

I would always want to play HOD, but never could get through it. Years later I brought the Saturn game ( yes the Saturn ), and it came with two variants

1. The original Arcade

2. The updated arranged game for the Saturn with meh better graphics ( or something along those lines ).

Somewhere I have "Typing of the DeaD" ( For the Dreamcast of course ). I could halusanate all day long thinking about Zombies, and babes worth looking at...

Thinking about that first boss demonic-bat creature, to the grand final inside of that factory ( or whatever place ).

If I am mistaken on the Dreamcast ( which I have ) there is a beat-em-up game ( not Gun-spike which I also have ) but another Zombie busting with some meh girls I guess, but the biggest thing I enjoy is the intro with the PPC. My dad owns a couple of those mini-computers. He probably tossed them all in the trash or whatever by now ( that is the kind of person he is ).
Just seeing that green desktop makes me think about running an emulator on a PPC Windows machine ( as it was promoted as being use for the Dreamcast ).

Yes you could make Pocket-PC based games for the Dreamcast work.

Only thing close to "HOTD" could possibly be "Sweet Home" but that game is a First-person shoot-em/slash em-up/beat em up timer, where you must slay the enemies and not allow your team members to "taken" all the while the insanity of the enemies that tears into them and you, is almost overwelming.

Nice walk down memory lane. That and the Segata Commercials. Which proves how the western view of marketing was lame. Like with HD, XP, AI, and other rubbish they add at the end or beggining of everything. Even Advance was lamer then saying Super or 2000.
