The MAME team has done a great job with loht, it now emulated beautifully all the way up to and including the 7th level (last level). I haven't seen the final boss though.

However, I believe that the dip switch settings (which are labelled unknown) are set on super hard. This game was never this hard in the arcade. I know because I used to finish it with ease. Does anyone else have any thoughts on this? I've got a recording that goes to level 5 that I'll upload over the next couple of days. This is going to be a tough game to finish on current settings.
