And what he would have found with some basic research exactly?? The only information you can find with google on this bootleg is the pictures he posted (and a few more but still from the same origine).
Like me, he is a single post user here and the way he was answered until now is very friendly: welcome!
When I saw these pictures the first time I was also very surprised that a bootleg of a such famous game could be apparently so rare and so less documented on the internet and that's probably why it's still not included in MAME (no dump and no board available) and yes for sure it would be a great addition to the MAME set.
