Need advice for incorporating jukebox into MAME cabinet...

[MaxVolume]

A long time ago in an apartment not far away, I had a nice fat "lowboy" Missile Command cab that I intended to transform into a digital jukebox.  Sadly, I left that apartment and moved to a much smaller one, where I don't think the cab would have even fit up the stairs, so I got rid of it and my other full-size cabs. 

Zooming right up to today, I've nearly finished converting the second of my two remaining cabs (a mini, which has been with me all these years, along with a cocktail table) and I think I'm going to have to cram jukebox functionality into this project as well.  Obviously the cocktail project was out, since it only has a mono amplifier.  I did want to include pinball and driving games in the mini as well, but the construction of the cabinet prevented the addition of flipper buttons.  That was a blessing in disguise, since it's now possible to do a two-monitor project with LCD displays.  I still plan to include driving games, but they will have to be played with a trackball. 

As for the jukebox, it actually makes sense since the theme of the project is FLYNN'S, and of course there was a jukebox in the arcade.  Not only that, but the 3DArcade frontend that I plan to use apparently supports launching jukebox software when you approach a "virtual jukebox" placed inside the arcade.  My first thought was to try and simulate the Seeburg SQS-160, which is the jukebox they used for the ComiCon version of FLYNN'S, and I think that's the one that's shown in TRON Legacy as well.  I'll have to go back and check to see if the same model was in the original film.

Anyway, I was thinking of using DWJukebox, since it seems to be sufficiently configurable, almost the MAMEWAH of jukebox software.  If I was going to go with the look of an SQS-160, I'd need to start with reference photos of the display area where the title strips are to get an idea of the numbering scheme, fonts, etc.  The only problem is that I've sort of backed myself into a corner with regard to my control panel.  Funnily enough, I have the exact same Targus keypad that the guy who made the "Photo Skin" for DWJukebox uses in his YouTube video, but I've had some trouble getting MAME to recognize a lot of the keys.  It's not impossible that I might repurpose it for the FLYNN'S jukebox if it works well for that, so I guess that would be a way around the limitations of my control panel.

However, in looking at another DWJukebox skin, I was reminded that older jukeboxes used a letter/number system.  Since I knew I'd be including most of the NEO GEO games, I did label my buttons A-F (I have two extra buttons beyond the NEO GEO ones).  I had thought I could have people press the button for whatever the letter was, then hold the joystick up and press another button for a number between 1 and 6.  The only issue with that is how I have the buttons arranged.  "A" is on the bottom, followed by extra buttons "E" and "F", while "B", "C" and "D" comprise the top row, shifted a bit to the right.  This preserves the pattern of buttons A-D on a NEO GEO machine, but it would probably make it difficult for people to guess whether A represented "1" or "4".

Now that I've typed all this, it does seem best that I just use the keypad as long as it works well with DWJukebox.  I bought it because it has a "TAB" key, which a lot of others I looked at didn't, and the plan was to use it as sort of a "remote" for my cocktail table in terms of changing settings, etc.  I guess since half the buttons didn't register properly in MAME, the best use of it might be as a remote for the virtual jukebox.

So, if anyone has good photos of a Seeburg SQS-160, please post them.  Once I've had a chance to download DWJukebox and make sure it's the right software for what I want to do, as well as deciding on the SQS-160 as my model, I'll probably post a photo request thread as well.  For now, if anyone has other recommendations, or other thoughts on the dilemma I described above, feel free to chime in.

Thanks!
