pSX readme


pSX emulates the Sony Playstation 1, pretty much everything is emulated
(to my knowledge) and most games run perfectly.  It runs under Windows and

One thing that should be noted is that pSX DOES NOT use plugins.
The emulator is completely self contained.

The emulator has been designed to be as easy and unobtrusive to use
as possible - in most cases you will not need to configure anything
to use it (except maybe the controls).


Extract all files from the .rar (or .tar.bz2 file under Linux) including

The emulator requires a PS1 BIOS file which should be placed in the
bios directory.  By default the emulator will look for scph1001.bin
- this version is highly recommend because it is the only well tested
one although other bioses should work.

Once the emulator is running you can change the BIOS from the
configuration menu.  In the event that you only have a different bios
file you can edit psx.ini to get the emulator running (run psx.exe
once, you will get an error message, now look for psx.ini).

Installation notes for Linux

Under Linux pSX requires the following shared libraries/packages :


pSX will store its settings in ~/.pSX (the memcards, saves and screenshots
dirctories will also be created here).  If psx.ini is present in the
application directory it will be read from there instead (for backwards
compatibility with verions before v1.13 - you can also move psx.ini here if
you don't want per-user settings, remember to make it world writable though
otherwise users will be unable to save any settings).

Running games

The emulator supports .cue/.bin, .ccd/.img/.sub, .iso, and .mdf/.mds CD
images, the easiest way to run a game is to run the exe then select "Insert CD
image" from the File menu. It is also possible to start a game from the
command line:

    psx.exe c:\psxgames\mygame.bin

or under Linux :

    pSX /usr/psxgames/mygame.bin

Note that you will get best performance running in full-screen mode.
Press ALT+ENTER to switch between full-screen and windowed.

CDZ images

pSX supports compressed CD images which are called .CDZ files.  They can
either be created using the built in converted (File/Convert .BIN to/from
.CDZ) or by using the cdztool.exe command line utility.

.CDZ files can be created from all image formats that pSX supports.

To create a .cdz file utils cdztool :

    utils\cdztool.exe c:\psxgames\mygame.bin c:\psxgames\mygame.cdz

You can also convert a cdz back to .cue/.bin by reversing the order of
the parameters, eg:

    utils\cdztool.exe c:\psxgames\mygame.cdz c:\psxgames\mygame.bin


The configuration menu is fairly self explanatory.  This is a quick
run through of the various options.


This tab allows you to set the default paths for state saves, memory
cards and cd images.


This tab allows you to set the BIOS image used by the emulator.

Memory cards

This tab configures the memory cards inserted into the Playstations
slots.  To create a memory card click ..., navigate to where you want
the file to be saved, and enter a filename (eg. "mycard").


Bilinear interpolation - enabled/disables bilinear filtering when stretching
frame buffer to window.

Frame skipping - enables/disables frame skipping

Sleep when idle in windowed mode - when running in windowed mode this
option causes the emulator to use less CPU time but can result in
choppier performance.

Pause when not focused - when enabled the emulator will pause when its
main window does not have focus (note: sound is always disabled when
not focused).

Status icons - displays status icons (CD/XA/etc..) at the bottom left

Full screen mode: can be configured separately for PAL and NTSC.  In
most cases these should be left on Default which will use the most
appropriate mode for the PS1 (Note: setting a mode that does not have
a refresh rate of 60hz for NTSC, or 100hz for PAL will result in less
smooth emulation).  You can select which monitor fullscreen mode will use
(default = use whichever monitor the window is on).  Aspect ratio correction
can also be forced in this dialog (the default setting is Auto which will
apply aspect ratio correction based on the resolution of your desktop - this
should do the correct thing for 99% of people).

Display adjustments: gamma, brightness and contrast can be configured.  These
options only affect full screen mode (most cards only support a gamma ramp in
full screen mode).


This tab allows you to configure joystick and keyboard mappings for
the Playstations controllers.

Note that you MUST configure the gamepad controls if you want to use
a joystick or gamepad (by default only keys are set up).  Also note
that you must configure the analog axes if you want to use an analog
controller (eg. dualshock).

Default controls (for port1) :

  Up        Cursor up
  Left      Cursor left
  Down      Cursor down
  Right     Cursor right
  Triangle  A
  Square    X
  Cross     Z
  Circle    S
  Start     Return
  Select    Space
  L1        Left shift
  L2        Left ctrl
  R1        Right shift
  R2        Right ctrl


From this tab you can configure sound settings.

Device: set the device used for sound output, in most cases this should
be set to "Primary Sound Driver"

Frequency: normally you should leave "Same as emulated machine" checked
which will cause the emulator to use the same frequency as the PS1.  To
change the output frequency untick the option and select from the combo

Latency: This option controls how much delay there is in the sound output
in most cases the default setting will be fine, but if you experience
dropouts or choppy sound you can try increasing this.

XA latency: Controls how much delay there is in XA sound output.

Reverb: Enables/disables reverb emulation.

Sync sound: When enabled the emulator will try to keep the sound in sync
with the graphics (this should normally be enabled).

Interpolate: Enables/disables linear interpolation of sound output -
takes slightly more CPU power (not much) but reduces aliasing significantly.


Allows redefinition of various miscellaneous keyboard controls.


Allows selection of CDROM driver (Auto detect, IoControl or ASPI) - normally
Auto detect should be used.

ASPI Drive letter mapping under Win98/ME

Under Windows98/ME there is no way to correctly map drive letters to ASPI
drives.  Because of this the emulator makes a guess (it guesses that the
drives are in order of scsi adapter/target) - if you have multiple drives it
may guess wrong.  For this reason it is possible to override the mapping.

To see what pSX thinks the mappings are run the emulator with the -x option:

psxfin -x

This will show a list of drives with the corresponding drive letter on the
left.  If this is incorrect you can add entries to the [CDROM] section in the
.ini file to override it, for example :


This tells the emulator that SCSI target 4:1 is drive x:

Crash dumps (Windows only)

If the emulator crashes it will ask if you want to save a crash dump.
There are two types of crash dump, mini dump and full dump - a dialog
box will ask you if you want to save a full dump.  In most cases you
will want to say no to this because full dumps can be very large - a
mini dump is usually enough to debug problems.

Dump files can be included in a bug report (see email address below).

NOTE: crash dump saving is only supported if you have dgbhelp.dll installed
