There is a new port of MAME4All to the Dingoo platform, which itself is a port of MAME v0.37b5 so do not expect the more recent MAME roms to be supported. For this to work, you'll need Dingux, the Dingoo Linux distribution up and running on your Dingoo A320. This is this version's initial release, so there are no changes except that it now exists. You can get it
here, or over here on our shiny new
Mame4All Dingoo page.
