Does anyone know what device the roms on this site are based on in terms of Play Store Compatibility?

I asked because I got my tablet yesterday, flashed the 4.1 cleaned, rooted image from this forum and all is well. However, two apps I've noticed are incompatible are 'Modern Combat 4' and 'The Room'. I know I can sideload them but I've already purchased them on a different device and want to install them properly for ease of future updates etc. It's weird though becuase Viber and Whatsapp are compatible but aren't even officially available for tablets.

I've tried the 'Market Helper' app to spoof my tablet, it has great reviews but I just couldn't get it to work. The apps remained unavailable to download. Does anyone know of any other work arounds other than editing build.prop?

Thanks in advance for any help.

*EDIT*

The Market Helper does work but for anyone facing the same problem, it does not trick the Play Store app, you must log into the Play Store website and send it to your device from there.

I'm new to the forum so not sure if I'm allowed to post a link to Market Helper but it's easily found with Google.
