INTRODUCTION

Hu-Go emulates the NEC PC Engine console on many
system such as Linux and Windows. 
(see http://www.zeograd.com/ for details)

PSP-HUGO is a port on PSP of latest HUGO version.

Special thanks to my friend Nicolas C. for his
support and kindness, without him i would have never
found enough motivation to port Hu-Go to PSP.

- IR keyboard

  You can also use IR keyboard. Edit the
pspirkeyb.ini file to specify your IR keyboard model,
and modify eventually layout keyboard files in the
keymap directory.

The following mapping is done :

  IR-keyboard   PSP

  Cursor        Digital Pad

  Tab           Start
  Ctrl-W        Start

  Escape        Select
  Ctrl-Q        Select

  Ctrl-E        Triangle
  Ctrl-X        Cross
  Ctrl-S        Square
  Ctrl-F        Circle
  Ctrl-Z        L-trigger
  Ctrl-C        R-trigger

In the emulator window you can use the IR keyboard to
enter letters, special characters and digits.

LOADING ROM FILES (.PCE)
------------

If you want to load rom image in your emulator, you
have to put your rom file (with .pce file extension)
on your PSP memory stick in the 'roms' directory. 

Then, while inside emulator, just press SELECT to
enter in the emulator main menu, choose "Load Rom",
and then using the file selector choose one rom image
file to load in your emulator.

You can use the virtual keyboard in the file
requester menu to choose the first letter of the game
you search (it might be useful when you have tons of
games in the same folder). Entering several time the
same letter let you choose sequentially files
beginning with the given letter. You can use the Run
key of the virtual keyboard to launch the rom.

LOADING ISO FILES (.ISO)
------------

If you want to load iso image in your emulator, you
have to put your file (with .iso file extension)
on your PSP memory stick in the 'cd-roms' directory. 

LOADING HCD FILES (.HCD)
------------

HCD format describes CD tacks for Hu-go. 
Here is an example of that file format:

[main]
first_track=1
last_track=22
minimum_bios=1
[track1]
type=AUDIO
filename=Track01.mp3
begin=lsn,0
[track2]
type=CODE
filename=Track02.iso
begin=lsn,3890
....

See Hu-go web site for more details.

If you want to load a hcd file with all track datas
in your emulator, you have to put your file 
(with .hcd file extension) on your PSP memory stick 
in a sub-folder of the 'cd-roms' directory. 

Audio tracks are ignored so no need to copy them.

CHEAT CODE (.CHT)
----------

You can use cheat codes with PSP-Hugo. 
You can add your own cheat codes in the cheat.txt file
and then import them in the cheat menu.
All cheat codes you have specified for a game can be 
save in a CHT file in 'cht' folder.
Those cheat codes would then be automatically loaded
when you start the game.

The CHT file format is the following :
#
# Enable, Address, Value, Comment
#
1,36f,3,Cheat comment

Using the Cheat menu you can search for modified bytes
in RAM between current time and the last time you
saved the RAM. It might be very usefull to find "poke"
address by yourself, monitoring for example life numbers.

To find a new "poke address" you can proceed as follow :

Let's say you're playing PC kid and you want to find 
the memory address where "number lives" is stored.

. Start a new game in PC kid
. Enter in the cheat menu. 
. Choose Save Ram to save initial state of the memory. 
. Specify the number of lives you want to find in
  "Scan Old Value" field.
  (for PC kid the initial lives number is 2)
. Go back to the game and loose a life.
. Enter in the cheat menu. 
. Specify the number of lives you want to find in
  "Scan New Value" field.
  (for PC kid the lives number is now 1)
. In Add Cheat you have now one matching Address
  (for PC kid it's 0DAF)
. Specify the Poke value you want (for example 3) 
  and add a new cheat with this address / value.

The cheat is now activated in the cheat list 
and you can save it using the "Save cheat" menu.

Let's enjoy PC kid with infinite life !!
