I'm currently playing the gameboy double dragon.... Started it in the last week or so..... I'm on mission 4.... But not quite got it down yet.
I've owned the original double dragon arcade board.... Its one of the first games I beat on 1 credit in the arcade bitd
Double dragon 2 arcade... Once u get the controls down... Its decent
I've completed 1 and 2 on the famicom in the last couple of years too.
I like the home versions I've played and the devs did a great job on the music on the home versions I've played
