I'm in the initial planning stages for a Burgertime bartop-mini! I've been thinking about a bartop-mini project for some time now, mainly for the purpose of having it at work on my desk to play during breaks.
This project is going to start sometime in the Q3, Q4 portion of this year, so I figured I'd get a post going on it now.
Here's a quick mock-up, I will be tweaking it as I concentrate more on this project:

Burgertime is one of my favourite games of all time, as well as one of the nicest looking full-sized cabinets!

The artwork and game seems so welcoming. I love the graphics for both the artwork and in-game sprites. The music is rad, and the game-play is fun!
I was thinking that I could put in a 60-in-1 board in it instead of a mame machine, because it would be smaller and easier to fit into this sized cabinet. I'm throwing in a 8" (4:3) LCD screen from
DealExtreme.
I haven't put much thought into the actual dimensions, but I know I want it to be small-formed, and easy to sit on the corner of my desk (I'll have to mock it out with cardboard or something). I'm taking a lot of queues from
Ryglore's Centipede bartop (though unfinished!),
Leapinlew's Galaga,
eaconner's DK bartop, and
shrunkenmaster's Dig Dug bartop.
I'm thinking closer to the size of Leapinlew's galaga bartop, though definitely not as deep due to the fact I'll be using an LCD. I just gotta make sure Burger Pete will fit on there!

I like proportions of the joystick/buttons to the cabinet size on his bartop.
Controls-wise, I'm going for a 4-way setup (possibly a JLW that I've got laying around here) w/ micro-switches -- considering using those Versa-micro-switches from GGG and doing
Ond's switch mod for silent running. In fact, I should be doing this for all my joystick switches! Also, a single leafswitch push-button. I've got a few white ones laying around here from other cabinets.
I want to keep the CP as clean as possible, so I'm planning on of either small midway cocktail start buttons:

or perhaps, atari cones

.
Progress will be slow on this one, hopefully I can get this one done before year's end (juggling a lot of projects at the moment).
