Well, I made the decision tonight to put the Dreamcast inside my control panel. With my 4 player design, it fits nicely. I drilled 4 holes for the controller ports on the left and right ends of the back of the control panel (won't see them under normal conditions), and I am letting the glue dry that is holding the controller extension cables in place. That way, I will just have to plug in my favorite DC controls to the back of the control panel and keep things nice and clean looking.
I did have to drill (using a medium hole cutter attachment) an opening in the back center of the control panel. Everything else is USB for the MAME stuff and I have a 4 port USB hub, that doesn't require power, inside the control panel and have a 6 foot USB cable so that I have 1 connection to the PC, but now with the DC going inside, I needed a hole big enough to get power in and video/audio out of the DC. I will need to use a RCA style extension cable for the video, and I will have to use an audio converter to go from the RCA right and left audio to "headphone" style and then run a splitter from my powered speakers so that it can take inputs from the DC or the PC. Should be good.
I am going out of town for the weekend, so I won't be back to the project until Monday night when I plan to finish covering the sides (left, right, front, and back) of my control panel, and then get the control panel base mounted on to the cabinet. Then comes the fun wiring job, and then attaching the top to the control panel base. My goal is to be done with that by the end of next week and then next weekend get MAME tested and running. Somewhere in there I need to get the speakers mounted (holes are already cut), the marquee light mounted, and the artwork on. I will finish up with getting the PC power on/off button moved to on the cabinet itself, and if I feel really gutsy, take the TV remote apart and set up a button for that too to turn it on/off. Once all of that is done, I will put the front glass in place (haven't ordered it yet, but don't want it laying around just asking to be broken), and THEN I will finally get around to getting the Dreamcast fired up.
I've come so far, and yet have so far to go....
