EARTH SHAKER EDITOR
by Sai Ming Wong
from Your Sinclair 67 (Jul.1991)


Remember the rather splendid Earth
Shaker which we gave away on the
front of issue 63? Fab, eh? At least it
is until you've completed all 32
levels at which point it seems destined for a
dark and smelly future under your bed. Until
now! Sai Ming Wong's editor lets you tweak
each level, rearrange them into a different
order or even design a load of new ones from
scratch. Corks!
	To get it going, follow these simple steps.
STEP 1 Type in the first listing, which
replaces the game's original loader, and save
it onto a tape with SAVE "EARTH" LINE 10
STEP 2 Reload what you've just saved and
insert your copy of Earth Shaker into the
recorder. After it's loaded, you're given the
option of loading or saving levels before the
game starts. Line up a fresh tape and press
'Y'. A couple of files are saved containing all
the original levels ready to be edited.
STEP 3 Type in the second listing - the editor
itself. Hexophobes will be o'erjoyed to see that
it's all written in Basic. Note that the capital
letters I've underlined in lines 25, 5001, 6135-
6138 and 9020 are UDGs and should be
entered in Graphics mode. Save the results
onto yet another tape with SAVE "EDITOR"
LINE 1.
STEP 4 Reload the editor and (hopefully) it'll
run, presenting you with 4 options:
*	Option 1 loads in a saved set of levels (eg.
the ones you saved in Step 2).
*	Option 2 saves a set of levels ready to be
loaded into Earth Shaker.
*	Option 3 inserts a level from memory onto
the screen so you can edit it.
*	Option 4 lets you edit what's on-screen.
	So an initial plan of action should be to
select Option 1 to reload Earth Shaker's
original levels, then select Option 3 to call up
the level you want to edit and then Option 4 to
enter the editor. Got it?
	Once you're in the editor you find that keys
Q, A, O and P move your cursor (a star)
around the grid, while a variety of other keys
listed down the right-hand side of the screen
plonk objects into the grid. Don't forget that
each screen needs a player start position and
an exit. Having arranged everything, press G
to place your new level in memory, choosing a
number from 1 to 32 according to
whereabouts you want it. After a shortish
delay you'll be asked about your level. Most of
these are to do with the colours you want, with
current colours appearing in brackets. Finally,
type in a name for your level and you'll be
returned to the main menu to save it.
	To play your revised version of Earth
Shaker, follow Step 2 to load in the game and
press 'N' when asked if you want to save
levels, and 'Y' when asked if you want to load
some.
	And that's it.
