Hi, new here but have been following MAME for many years but finally building my first cabinet at last!

Ive searched on here for ideas but cant find anything specific to my needs so forgive me if its been posted before but there is so much info on here to search through

, anyway here goes....
...I need some ideas for a control panel layout for a 2 player 30" wide cabinet (although it can be a modular contol panel that is wider than the cabinet if needed) which will be used for mainly street fighter type games MK KI SF etc, classic asteroid & defender type games but more specifically which is causing me headaches is it must have dual joysticks per player for Smash TV etc (I love that game!)
Im thinking of standard street fighter layout per side with the extra 7th thumb button per side but cant decide if to fit the second dual joytick to the right of the button layout or to the left of the standard joysick? Im thinking of using a top switchable 4/8way stick for the main player 1 stick and using the existng street fighter type buttons for all the games i will play (either on P1 side or P2 side depeinding what feels comfortable?)
Somewhere Id also like to fit a trackball if possible and Id like to keep the layout as simple as possible to keep an authentic look so Im only going to use one admin button as a pause and use the ipac4 with player 1 button to shift & pause to escape games, any other admin could be done by shift button 1,2,3 etc for functions like TAB etc (im hoping anyway?)
Id like your thoughts and suggestions on how to lay this lot out or improve/modify my thoughts as Ive not built one before so dont know whats tried n tested or what dont work!

Cheers people.
