Control Panel layout design

[xwildzerox666]

Hiya, I'm kinda new so apologies for any big faux pas.

I've got a cabinet (an old mortal kombat/gauntlet style one), and I'm planning to 'rebuild' the control box to accommodate some extra controls. I just wondered if people had any experience/feedback on this idea, especially regarding extra buttons (tab ot menu, enter, pause etc...how many do I need?). I'm currently plumbing for a sort of Luicid design with:

2 joysticks with 6 buttons each in the centre-front
2 joysticks with four buttons each either side of these.
A trackball in the middle.
Buttons across the top -

1,2,3 and 4 player start.
Coin in.
Pause.
Enter.
Tab - to MAME menu.
Escape - to rom select menu.

Have I missed any here? Do I need all these?

I've also inherited an awesome yoke joystick with this cabinet, and I'd like to fit it in there somewhere, but I'm sort of stuck for where...is in front/behind the two central joystics going to be anooying and in-the-way? Anyone got any experience of trying to fit too many things on?

You have everthing for a 4 player cab.  But I wouldn't put a Pause, Enter, Tab & Escape button on the panel.  As the IPAC/4 has shift buttons to handle these.

Some games require a separate coin door switch for each player.
