Atari 800 XL - Arno Boulder Dash 5, caves 1, 3, 4 & 5

Arno Boulder dash is a set of BD level compilations created by Arno Weber. Many of them are quite interesting, and all are difficult. There are 20 series of Arno Boulder Dash, but they mainly exist for C64. Only the first 6 are adapted for Atari. I personally prefer playing on Atari and hearing Atari sounds, so here is a completion video of another three good caves from these series.
