Quoted from wxforecaster:There are a variety of XX in 1 Jamma boards out there, some (iCade revision A) better than others, but none as true to real as they don't use the real ROMs. Casual players may not notice the difference, but purists will be able to spot the errors in game play, colors and/or sounds. As others have stated, you get what you pay for. I retrofitted my original ms Pacman cocktail w/ two new control panels (with 2 fire buttons), an adapter card and an iCade 60-1 so my kids could play a variety of games on it and I could keep the machine all original with just a 10 minute swap. That said, I also have a DK Jr (and DK board to play both), BurgerTime, Dig Dug and Vs. Unisystem. There's something to be said about the original cabinet, control panel, marquee, look, feel, etc... If DK is a game you want, I'd honestly recommend staying original. With the Kong Off's there are PLENTY of DK cabinets to go around and you should be easily able to acquire one for a few hundred bucks. The benefit is that you can swap in a DK Jr and DK 3 board just by swapping out the connectors (I have a spare DK Jr board if you get to that point).
I tried an xxx in one before, the most expensive and top of the line too. I gutted it immediately. Those XXX in 1's SUCK! Do it right if you're going to do it and do a computer emulated MAME.
