It's time for me to start my latest project. I am finally getting around to building my MAME cabinet. I've been pretty picky deciding what old cabinet to start this project with, but I finally found it. I am a huge Neo Geo fan and I have been looking for a MVS upright in decent shape. Finally one popped up on craigslist in my local area. I don't have any pictures of the actual cab I have purchased yet, because the guy I bought it from can't deliver it for a few days. So the next few pictures I post are generic google images.
The cab is basically identical to the MVS-1 slot pictured at far left.

Now this will be my first MAME anything, so please excuse the stupid questions and if you answer one please don't be too specific that I don't know what your talking about.
First things first, the Neo Geo's only have 4 buttons. This just wont do, but fortunately there is plenty of room to add 4 more. I made a couple crappy photoshop mocks to see how it might look with the added buttons. I would of course have a custom control panel overlay made to accommodate these extra buttons.


I think I like the white layout the best as it keeps a kind of stock feel even with 4 added buttons, though I may move the Red A button to top left so it wont be too confusing when playing actual neo geo games. What do you guys think?
So my first real question is this... what other buttons do I need for controlling MAME? I cant find this info anywhere. Things like start or esc buttons? What else is required or would be nice to have? I really dont want to finish this project only to realize that I need another button or two for controlling other aspects of MAME. There should be plenty of room where the player start buttons are to add these controls.
I plan on using the Hyperspin front end as it seems to be the coolest and best organized.
I'm sure I am going to have a TON more questions as I finally get this thing home and start to work on it, so please check back often and help me out! You can expect a lot of pictures of the build. Also, if this isn't the best place to have posted this thread please let me know where is? There doesn't seem to be an obvious place to post MAME stuff here.
Oh also forgot to mention. I restored at MVS-2 Mini 13 awhile ago. Did a number of upgrades as well as the restoration. Here is a few pics of her.
