* GBUK VERSION 1.01 *
* 30th January 1997 *

********************************************************
WHAT IS IT?
It is a gameboy emulator that works on an Amiga with a
68020+ processor and 256 color graphics. It is based on
the Unix emulation written by Marat Fayzullin. The game
carts are loaded off of files which are themselves memory
dumps of gameboy carts.
INSTALLING
To install the program, all you do is create a directory
on your hard drive, say dh0:gb, then extract the archive
into that directory. To run the program you now open a
CLI window, set the current directory to the one you
extracted the archive to and type GBUK.
USING THE PROGRAM
When you first run the emulator, after a short pause you
should come to a screen where you can choose the game
cart that you want to load. Hopefully, the operation of
this bit should be straight forward. If it's not, see the
explanation below under LOAD.
Once you have selected a valid cart you will be in the
game proper. From here you can control everything just
like on a normal gameboy. The keyboard equivalents for
the buttons and joypad on the gameboy are as follows:
+-----------------+------------+
| Gameboy | Keyboard |
| | equivalent |
+-----------------+------------+
| Right on joypad | 6 on |
| | numerical |
| | keypad |
+-----------------+------------+
| Left on joypad | 4 on |
| | numerical |
| | keypad |
+-----------------+------------+
| Up on joypad | 8 on |
| joypad | numerical |
| | keypad |
+-----------------+------------+
| Down on joypad | 2 on |
| joypad | numerical |
| | keypad |
+-----------------+------------+
| A button | Left shift |
| | |
+-----------------+------------+
| B button | Tab |
| | |
+-----------------+------------+
| Select | Left Alt |
| | |
+-----------------+------------+
| Start | Control |
+-----------------+------------+
If you like, you can change these options using the
Keyboard preferences described below under KEYS.
If you want to access the main game menu at any time,
then you just press F2 or else press the right mouse
button. The currently selected option is always
highlighted in red. To change the current option either
click on the option you want with the mouse or else use
Up and down on the keyboard (the keys that correspond to
up and down on the gameboy). To go to the option you
selected, press enter or else double click on it with the
mouse button. Here is a description of what the various
options do.
LOAD: This brings up a file requester allowing you to
choose the name of the cart you want to load. It works in
the following way. On the left of the screen is a list of
files and directories. The files are in black and the
directories in red. If you can see the name of the file
you want to load, just double click on it with the mouse
pointer. If you don't see the name of the file then you
can scroll down the list using the up and down buttons
and the scroll bar. If you still don't see the name of
the file you want then you can change to another
directory by double clicking on one of the directory
names or else you can go back a directory level by
clicking on parent. If you want to examine another drive
attached to your computer then you click on the button
VOLUMES and a list of possible drives for you to choose
from will be shown. If you would rather type in the name
of the file than scan down a long list of files then you
can do so by clicking on the long oblong box at the
bottom of the screen with you mouse and then just typing
in the name of the file followed by return.
If the file you selected doesn't exist or else isn't a
gameboy file, you will be told so with an error message
and then returned to the file selection screen. If you
want to abandon this part, then you click on CANCEL.
PALETTE: This lets you choose the actual colors that are
used on the gameboy screen. So that you can better
understand what this bit does, I will first explain how
the gameboy palette is organised.
The palette on the gameboy is split into four parts, each
having four colors. The first two parts are used by the
sprites. The third part is used by the background (for
example, it might be used for the hill and clouds in the
distance on a platform game) and the last part is used
for what is called the window. The window is usually used
for the score line and stuff like that. Each of these
sections uses four colors. On the gameboy itself there
are only 4 colors from which each of these palettes can
be chosen from (4 shades of grey). On the emulator you
can set the colors to any of the colors of the rainbow.
To changed a color, you first of all click on the box for
the color you want to change and then use the sliders on
the bottom right of the screen to change the amount of
red, green and blue in it. So that you can see the effect
that your changes are having, a copy of the current
gameboy display is shown on the left side of the screen.
Once you are happy with your changes you click on OK. To
cancel your changes, click CANCEL, this will restore the
colors as they were.
KEYS: This option lets you change the equivalence between
buttons on the keyboard and buttons on the gameboy. On
the left of the screen you see written the name of the
buttons on the gameboy. On the right you see what the
keyboard equivalents for these are on the emulator. To
change an option you just click on the one you to change
with the mouse. It should now be highlighted in red. To
change it press return followed by the key you want. Once
you are happy with your selections you just press okay to
accept them and return to the game. If you messed up then
CANCEL will return you to the game but no changes will be
made.
SAVE: This takes a snapshot of your current game position
and saves it to disk so that you can load it back again
later. You select the file name through a panel which
works exactly the same way as the one used for selecting
a cart to load. See above for an explanation of how it
works.
GRAB: This lets you save the current gameboy screen as a
picture file. You select the file name as described above
under saving games. The picture is saved as an LBM (as
used by deluxe paint).
QUIT: Abandons the game and returns you to DOS.
CANCEL: Abandons the menu and returns you to the game
where you left off.
CHANGING PREFERENCES
All the preferences for the program are contained within
the file PREFS in the same directory as the main program.
This file is basically just a text file with each
preference set in the following way:
VARIABLE=VALUE
Each of these variables control something to do with the
program. For example this line:
FONT_GFX="GFX/TOPAZ11.PIC"
Says that the graphics for the font can be found in the
file GFX/TOPAZ11.PIC. From this I hope you can see how it
works. Most of the preferences you will actually want to
change can be set in the program itself by going to the
palette options and keyboard options. One variable you
might want to set yourself though is the one controlling
the speed of the emulation. The name of this variable is
SLOW_DOWN and basically, the bigger the value is the
slower the emulation. Its value can be anything greater
or equal to zero.
Another variable you might want to change is METHOD. This
variable effects the accuracy and speed with which the
gameboy's graphics are emulated. If method=1 then the
graphics are inaccurate but quick and if method=2, the
graphics are more accurate but slower. The main thing
that goes wrong when using method=1 is that the palette
will go wrong slightly sometimes but for most carts I
have tried its all right.
GETTING THE FULL VERSION
This version is only a demo. It has all the features of
the full version except that it has a ten minute time
limit on its use. That is you can keep reloading and
playing 10 minutes at a time, but you can't play
continually.
To register for the full version, print off the following
form, fill it in and send it off to me together with a
cheque for 10 UK pounds. If you live outside of the UK
but in europe then you can send me a euro cheque. If you
live elsewhere then you order it by sending me a bankers
cheque for this amount in UK funds.
If you don't have access to a printer just write out the
form on a bit of paper and then fill it in.
