No problem.
I can make an zip image of it for you if you want (without the rom's of course!) should be ok - its all freeware (freedos, vantage, glaunch...)
This is basically what I did (going from memory)
Basically I bought a IDE -> CF adaptor.
Plugged it in, formatted it as a bootable drive.
fdisk (create partition)
format d: /s ...
I then tested it booted ok in the would be cocktail machine.
Pulled out the card, threw it into a card reader, and copied over vantage.
The next steps were done back and forth from internet connected pc -> cocktail pc as required.
put a rom into the roms directory (1942 as it is easy to test flipped), and checked that vantage ran. Unfortunately the test only lasted till about level 20 odd before I lost all my planes but I digress

(Testing *is* fun for these projects!)
Had to play around a little for the flip mode in vantage - easy enough - just modify the config file.
Once that was done I did some searching for the dos sound drivers (thats the hard part!), and got sound going.
I then added glaunch in, and configured it just to run using the mame.cfg, mame.rom settings.
(in glaunch/config delete anything except mame.*)
I added in the games manually - I'm only using the ones vantage supports, and only the 'good' ones - i.e. a handful of games.
Checked glaunch ran, and set it to run sideways also so it would look good for the 1st player.
added himem.sys, smartdrv to config.sys for a little speed boost (it has 128M ram)
Edited autoexec.bat to load everything and checked everything ran ok on boot.
Most games I had to change the dip switch settings to cocktail, and reset them.
(Tab, set cocktail mode, some also have a flip screen option if its upside down for player 1, then reset game. Vantage autosaves the settings, so its a once off process for each game.)
Vantage is about 2m total, dos about 1m total, roms - barely 500kb, glaunch (can't remember offhand).
It all fit in at around 4M.
I had the Desert Planet mp3 lying around, and thought it was perfect for an arcade machine.
When you turn on the cocktail, glaunch boots - starts playing the mp3, and you choose a game, then play it.
I still need to put in extra buttons for 2nd player coin, and escape from game - right now i haven't made an escape button so its power on/off to change. This is fine for its current application - it might stay that way, or i make a recessed 'reset' somewhere else.
PC is set in the BIOS to turn on when power is turned on. So no buttons needed, just plug in the power and everything boots on. I also turned off all the tests in the BIOS (usually something like Quick Boot or similarly worded)
It all boots quickly (like 5 seconds to glaunch menu) and off of cf, so i'm not worried about things getting corrupted if people power on /off rapidly - i think its all read only anyway up to vantage loading.
Really - the most complicated part of it all was finding drivers for the sound card. I had to try a bunch of them to find one that worked.
The best computers are the ones with generic sound AC97 chipsets - eg RealTek , ALi or other taiwan brands.
They usually have drivers available on the web for dos.
Newer computers don't necessarily have dos drivers lying around to find.
Soundblaster cards are a pain. (I've tried a couple, and find that other peoples sound cards are so much easier to get going in dos.).
I've looked at linux, but for this kind of application, dos is best - linux doesn't like power on /off, and mounting a filesystem read only is a hassle for a simple application like this.
But hey, I'm waffling here

I'm moving apartments at the moment, but will try take more pics tonight.
I have the MS Pacman printed out and installed, but someone split water inbetween the glass somehow, so its not looking so great.
I'm going to reprint the top again in a matt - gloss didn't work out well

Its only RMB50 for the top marquee mounted on board, so its no big deal.
RMB50 = $6.5 (or in real terms RMB50= 2 macdonalds big mac meal sets)
Again, if you need exact settings, I'll zip the whole shebang for you for download, and you can check it out.
you'll have to set the soundcard up yourself though - its going to be different for your motherboard than mine.
Cheers,
Lawrence.
