			LADDERS README.TXT

To run 'Ladders' you will need VGA video and the following files:
     LADDERS.EXE - the main program
     LADDERS.PAL - color palette for Ladders
     LASPRITE.LIB - all the sprites for ladders
     LATILE.LIB - background tiles
     MODERNFO.FNT -  a font file

Using a sprite maker program by Kai Rohrbacher called 'MAKES', you can 
make a personal copy of ladders with your own sprites! You will need
SuperVGA video and these additional files:
     MAKES.EXE - the sprite maker program
     MAKES.DOC - documentation for MAKES
     UNLIB.EXE - extracts sprites from a library
     BFFFFFFF.EXE - compression/decompression program
     SVGA256.DRV - a SuperVGA driver
You can extract the sprites in LASPRITE with:
	 UNLIB LASPRITE.LIB
This will give you 131 files, UNLIB000.COD TO UNLIB130.COD which you can 
load into MAKES and modify or replace.  Starting with UNLIB041.COD you have 
45 pair of blockers and carry items required to remove them.  UNLIB041.COD
is a door and UNLIB042.COD is a key. You may not want to change these but
any of the follow pairs might be replaced with your own drawings.  Carry
items should be centered in a 40X16 pixel rectangle so they show up 
correctly in the carry window.  Blocker items should be left justified with
their feet 40 pixels from the top. 
When you have the pairs changed as you want them type:
	COPY /B UNLIB???.COD LASPRITE.LIB
The 131 files will be recombined into a new library.  Run LADDERS and check
out your work.  IF you want to save some space, compress the library:
	 BFFFFFFF LASPRITE.LIB LASPRITE.TMP C
Rename or delete lasprite.lib and then rename lasprite.tmp to lasprite.lib.
You can also change tiles used to make the background by following a similar
process with LATILE.LIB.  In this case you get 18 COD files, 001 - 015 are
the 15 background tiles for the 15 different levels.  COD files for tiles
have to remain at 16X16 pixels.

I've include the source code in case you want to see it or modify it.  To 
recompile you will need Turbo Pascal 6.0 or higher and the TPU units
ANIVGA.TPU and MUSIC.TPU.  These are available in the ANI-VGA package by
Kai Rohrbacher.  It can be found on a Simtel20 mirror as ANIVGA12.ZIP.
I got it from  oak.oakland.edu /pub/simtel/msdos/turbopas.  Note that the
music.pas file (by J.C. Kessels) has been modified for the game included
with ANI-VGA. The numbers changed appear in 'PlayMusic' and 'Initialize' 
with the original numbers, (correct), in braces.
