Title: Donkey Kong speed Post by: KongJunkie on May 15, 2014, 05:02:04 pm Hey guys!
One month after fixing up my Donkey Kong Jr machine, I came across an original Donkey Kong machine, so naturally, I bought it. There's just two things that need adjusting. First, the color is off. I adjusted the brightness, but Donkey Kong and the barrels are still a deep reddish brown. The cables on the elevator levels aren't even visible between the platforms. I'm pretty sure you can adjust the RGB levels but I haven't found where. Secondly, and perhaps more noticeable, the game seems to play faster than every other DK machine I've ever played. I noticed the screen is narrow, so I need to adjust the vertical width, but I don't think making the screen wider is going to fix the speed. Has anyone ever experienced this before? If so, is there an adjustment I can do to fix it with? Thanks for your advice! Title: Re: Donkey Kong speed Post by: John's Arcade on May 15, 2014, 06:41:29 pm Hey guys!

I've never heard of fast DK but anything is possible. Title: Re: Donkey Kong speed Post by: KongJunkie on May 15, 2014, 07:18:27 pm You rock, John! Thanks again!
