Surprise-I want to build my own Sinistar game; I think it's an all-time great and I am not going to buy one on ebay that might not work or be messed up and cost hundreds to ship anyway. How do I go about it?
Okay -
First, a point of news - Sinistar used a very unique Williams 49-way joystick. This is not the same as the 49-way joystick that Happs sells, so you will probably need to pick one up from E-bay or the BYOAC buy/sell/trade, or RGVAC, etc. See
here halfway down the page for an exploded view of the joystick and
here for a replacement centering spider. Also, ignore the stuff about regular 8-ways if you remember the original game, it totally destroys the feel. Also see
this thread (plan a couple of hours to read through it (10 pages)) for a new way to interface the Sinistar sticks to the PC and for a good discussion of the gameplay.
First question is do you want a MAME cabinet that will work for many arcade games, a cabinet running MAME but dedicated to Sinistar, or a genuine Sinistar machine.
If you want option 1 then you probably will want the Sinistar controller on a dedicated removable panel, and you will probably want the GPWiz49 to interface it , but you can use a standard PC and any type of monitor.
If you want option 2, you don't need swappable control panels, so you could probably hook the 49-way joystick directly to the encoder, but you will want to use
MAME Analog Plus to control it. Also see
this page for a comprehensive discussion of 49-way joysticks and how they are used in MAME.
If you want option 3, you will need the correct monitor, boardset, power supply, joystick, bezel, sideart, marquee, etc., so while you could buy all this separately and put it into a scratch-built cabinet, it's probably cheaper/easier to buy a dedicated machine. I would either look on RGVAC or look for a local arcade auction rather than E-bay though, as you should then be able to try the machine out and verify it works before buying.
