I have some questions about this:
Are these real ROM-packs, or 5 Windows programs with emulators/titles built in? Are the titles working in a front-end or Mame itself?
If they are Windows programs, how true are they to the original arcade versions? Is the Windows program a Mame-like wrap for original ROMs?
Where can you buy these packs? I cannot find a dealer in Europe / good USA CC-accepting online-store by googling the titles of the packs?

I think information on packs like this should be in the Wiki. I searched it and did not find anything about these packs.

If you search the names on Amazon, you can see that Atari/Namco have a variety of game packs that you can purchase.

Atari
Midway
Namco
Capcom

You can pull up the Digital Leisure games at www.digitalleisure.com.

With the stuff on Amazon, you'll find a few different titles depending on the hardware (PSP, PC, Playstation etc) and a variety of games on different discs.  Not sure which ones they are using.  They are probably normal Windows programs with menus to select the game you want etc. 

And I am not saying that Amazon is where to get these.  I just find it easier searching on Amazon for certain things rather than Google as Google shows a bazillion links...
