As long as you own a Neo Geo CD that's all that matters. I own the good old unbeateable and unbreakeable top loader single speed or whatever it is and I love it, yes I do own all the same titles for MVS and all, but who cares!? I love the NGCD and I don't mind the loading everyone talk so much shit about. I can roll a joint, smoke it, eat some munchies talk some smack and still have a great time.
The best time I ever had with metal slug was on the NGCD during a MASS crew meetup with OSG, Saturn2Dfreak and phantom, it was great, if there wasn't any "intermissions" I don't think we would have been laughing so hard! I was talking crap laughing and eating at the same time all the time in mummy mode 'cause Saturn kept stealing the elixirs so talk about mega slow in a megaslowdown from hell, I was like Neo and the NGCD was the matrix!
That's the greatness of the NGCD who cares if you have to wait extra 30 seconds or whatever it is from CDZ to normal NGCD, I don't really give a shit, but as long as there is love in this thread for the NGCD then all is well with the world.
