Ah well...back on topic. Sorry guys

I downloaded Pong Rev E and learned a couple of things;
The Mac mangles the file download and labels it as pong.netlist so becomes useless
The PC downloads it as a .zip but the automated front end doesn't download it automatically
So I copied the .zip file directly into MAME/ROM and refreshed the MALA front end so it appeared in the main games list...along with about 100 other files as my games lost went from 952->1058 games!
Long story short; I select Pong Rev E from the main games menu, it says loading but then black screen and a request or pops up saying MALA encountered an error and do I want to send an error report to Microsoft.
No not really because the games PC does not have an Internet connection but even if it did I don't suppose for one minute Microsoft would be able or willing to help me!

So fountains of knowledge...where do I go to determine the issue here please?
I am running MAME 0.146, Haze said earlier that Pong has been back in since @2012 (0.146 was released May 2012) but the site I downloaded the ROM from made a vague reference to MAME 0.133 BIOS pack although MAME 0.164 appeared at the top of the page.
Nothing straightforward huh?
Also if I go back through the games list manually and trim out some of the rubbish that got thrown in when I refreshed the list what should I do to prevent it being thrown back in when I refresh the list in the future after I add another game?
Thanks & kind regards,
