I’m not 100% sure there is a “correct” way to mount this board. I’ve seen 3 different CPS2 games in their arcade form, and it typically depends on at least 2 things:
- Who owned the Cabinet previously
- Which type of Cabinet are you talking about?
In the case of Dynamo cabs, I can snap some pics of mine when I get home on Friday. I have XvSF in a standard size cab, the board sits on a piece of wood right behind the control panel, so everything is relatively accessed easily from the front. An SFA3 I looked at was almost identical in design.
At work, we have an MvC in a larger dynamo, not sure what to call this style really, but the board is mounted on the side in the bottom back area of the cabinet. Its actually quite annoying, because CPS2 boards don’t always make the best contact between A+B, and having one mounted on the side doesn’t seem to work as well.
Hope some of this info helps, I can snap some pics for you this weekend, just let me know.
