1. I like that you are going for an ergonomic button layout but I've found that it's way more comfortable using the attached layout instead of keeping the middle button raised.
I made a 1 player panel from scrap wood with this layout to use until the cabinet is built and it seems to be pretty comfortable so I'm sticking with it.
2. If you add a trackball make sure that one of the joysticks isn't in the way
That's why I thought I'd shift it to the left a little, but apparently this will make my cabinet explode.
3. I'm not sure what the dimensions are of that thing but it looks HUGE. I'm not a fan of 4P panels but a lot of people are so I won't go into that but yours seems much bigger than a lot of the other ones I've seen.
46inches across. So it's not quite as huge as some 50"+ ones I've seen.
4. I also think you should scrap buttons 5 and 6 on P3 and P4 as well as not angle the joysticks
Agreed. The more I look at the mockup the more I can't understand why I wanted them there in the first place.
5. Are you going to be using the 4/8 way switchable Omni-stiks? I'm not a big fan of the visible mounting plate but I guess you could work around it if you notch the CPO for the lever... seems like a pain though. I prefer a dedicated 4-way on there somewhere or something that is switchable like the t-stik or better yet the ultimarc 360 that you can map to do whatever you want. I've found that most people who play on my cabinets don't grasp the concept of switching from 4-way to 8-way for more accurate controls - they just want it to work properly. This is why I LOVE the ultimarc 360 - it makes the different control setups a non-issue.
I think you mean the Omnistick prodigy with the lever above the control panel, in which case.... no. My ones are the standard omnistick which are switchable from underneath. 8-way, 4-way, 2-way, even 3-way and 5-way is possible.
6. Spinner?
Still not sure about this. At the moment I'm leaning toward leaving it off.
Thanks heaps for all the tips. Invaluable!
