How many 2p games utilize 7 buttons?

[southpaw1]

I'm trying to do the layout on my control panel and I forgot about the extra button (7th button) that some 2p games use.  Its a tight fit right now on my CP for the 4 players and I was just wondering if its worth that extra button.  Thanks!

Also as of right now I have 6 buttons for all 4 players.  Are there any games out there that use all 6 buttons for 4 player games or do I only need 4?

if im not mistaken, 4 is all you need for P3 and P4

could be wrong..

Only if you're playing NeoGeo games.

In MAME there are no games that require 7 buttons.  The 7 button layout is so that you can play 6 button fighters or 4 button Neo-Geo games comfortably as they were on the original cabs.  There are absolutely NO 4-player games in MAME that use more than 4 buttons (I think it's actually 3).  The only reason to use more than 4 buttons on players 3 & 4 is if you are using consoles in which case you may need as many as 8 buttons per player.

Gotcha!  So if am thinking of emulating is it even worth putting 6 on since I'd probably need 8 anyways? 

Thanks for the input guys

Since you guys are being so helpful, how many "extra" buttons do I need on the CP to operate through mame and windows smoothly?  I was going to throw a jukebox shortcut button and volume control on there also.

If you've already got six, that's okay.  It will depend completely on how many buttons the console games you want to play use.

Admin buttons are personal preference as well.  If you use an Ipac, pretty much all functions can be done "shifted"   If you use the Keywiz you can use a Shazaam key to get shifted functions as well.  That way you don't have to have specific keys for admin functions.
