- *
- * Read emerald mine caves version 6
- *
- * v4 and v5 emerald mine caves are converted to v6 (which completely supports
- * older versions)
- *
- * converting to the internal format loses /significant/ information which can
- * break lots of caves.
- *
- * major incompatibilities:
- * - borderless caves behave completely differently, the player no longer
- * "warps" to the other side.
- * - a compile time option for spring can make it behave differently when it
- * rolls.
- * - a compile time option for rolling objects (stone, nut, spring, bomb) only
- * in eater.
- * - acid is always deadly even with no base beneath it (this breaks cave 0 in
- * downunder mine 16)
- *
- * so far all below have not broken any caves:
- *
- * - active wheel inside an eater will not function, eater explosions will not
- * change settings.
- * - initial collect objects (emerald, diamond, dynamite) don't exist.
- * - initial rolling objects will be moved manually and made into sitting
- * objects.
- * - drips always appear from dots.
- * - more than one thing can fall into acid at the same time.
- * - acid explodes when the player walks into it, rather than splashing.
- * - simultaneous explosions may be in a slightly different order.
- * - quicksand states have been reduced.
- * - acid base is effectively an indestructable wall now which can affect eater
- * explosions.
- * - android can clone forever with a clone pause of 0 (emeralds, diamonds,
- * nuts, stones, bombs, springs).
- *

- * - rolling stuff is now allowed in the cave, i didn't like making this
- * decision.
- * - if BAD_ROLL is not defined, initial rolling objects are moved by hand.
- * - initial collect objects break some cave in elvis mine 5.
- * - different timing for wonderwall break some cave in exception mine 2.
- * - i think i'm pretty locked into always using the bad roll. *sigh*
- * - rolling spring is now turned into regular spring. it appears the emc
- * editor only uses the force code for initially moving spring. i will
- * follow this in my editor.
