Sokoban (created in 1981 by Hiroyuki Imabayashi) is a transport puzzle in which 
the player pushes boxes around a maze, viewed from above, and tries to put them 
in designated locations. Only one box may be pushed at a time, and boxes cannot 
be pulled. This Exelvision version uses variants of the fifty original levels 
from Hiroyuki Imabayashi and produces a real challenge soon as the first level.

This game plays the role of a demo. It is built with video, sound, system and 
image API, helped with a development kit for Exelvision computer.

The game offers:
===============
  - 50 levels
  - a graphic intro
  - some music and sample sounds
  - a program 100% in assembler
  - high speed display
  - Exl100 and Exeltel compatible
and exists in 3 different versions:
==================================
  - a ROM cartridge version (convenient with an amulator): soko.rom
  - a floppy version (useful for exeldisk owners): soko.fd
  	enter the command EXEC SOKO on the exeldos prompt to launch the game
  - a K7 version: soko.k7 (dcexel) and soko.wav
  	This version requires only an Exl100 with a memory expansion (Exelmémoire).
  	It has  a simpler  intro image  and less  sound samples  because of the 16Ko
  	limitation.
  	enter the command RUN"1" on the exelbasic+ prompt
  	enter the commands LOAD"1" then RUN on the exelbasic prompt

Any version is compatible with dcexel emulator from Danial Coulom.
Only ROM version is compatible with the emulator from Gilles Fetis.

In the game commands (keyboard and main joystick compatible):
============================================================
  - cursor keys or joystick pad to move your avatar
  - space key or fire button to cancel the last (and only the last) move 
  - # and * keys to respectively increase and decrease current level
  - 1 key to reinitialize the current level
  - 0 key to go to the introduction page

The game is displaying information about:
========================================
  - the current level (blue frame)
  - the number of moves in the current level (red frame)
  - the number  of remaining boxes  in wrong places  (yellow frame): a  level is
  finished (you win !) when this  number is zero, and you pass  automatically to
  the next level.

Thanks to Daniel Coulom for  its very realistic and convenient  dcexel emulator,
to Sawa and Alexandre to spend  time with recording original japenese voice  and
to any people who have turn one's attention on my useless work or who help me in
any sort.

Sokoban has been made by Jester in June 2010.
