Rocks’n’Diamonds was partially able to read and play level files of this classic game since
about 20 years, but there never was an “official” level collection – until now!
This is a collection of classic level groups from the Amiga game Diamond Caves,
created by Peter Elzner in 1995 as a clone of the Amiga game Emerald Mine.

The level sets contain the game’s original Amiga graphics, and you can select
between the original graphics set using 16 colors and the enhanced graphics set
using 32 colors. Regarding sounds, you can select between the classic Amiga 500
style, low-pass filtered sounds, or the more clear Amiga 1200 style sounds.
Most level sets also include additional level set descriptions. The user interface
for this level collection was designed to resemble the Workbench 2.0 of the Amiga,
with the main menu screen modeled closely after the original game’s start screen,
with a few enhancements.

This level collection features 12 level groups that were exclusively available
for Diamond Caves, and 26 level groups converted from the Emerald Mine Club
collection to be played with Diamond Caves. Most level sets are designed to support
either one or two players.
Make sure to use the latest version of Rocks’n’Diamonds
to play it!
The new level package is available at the Levels & Artwork page!

This new release of the Emerald Mine Club level collection (which requires the
latest R’n’D version 4.4.2.0) adds full support for all 35 “Emerald Dash” level sets
in this collection.
These level sets use an improved, special version of the Emerald Mine game engine with some
differences similar to the classic Boulder Dash game (like BD style amoeba behavior),
but also things like voodoo players which have to be protected, or else the player will
be killed, too (as shown in the screenshots).
The new package also uses an improved native Emerald Mine sound engine which sounds much
closer to the original game.
The updated package is available at the Levels & Artwork page!
