Introduction

WARNING: Save states(and by extension, state rewinding and netplay) and saved games on emulated memory cards do not mix well unless you are extremely careful. For any given game, either use save states or the game's own save system, but not both, lest you may destroy your saved games.

A dual-core Phenom II or Athlon II at 3GHz or higher, or rough equivalent(in terms of single-core IPC), is recommended for running Mednafen's PlayStation 1 emulation on(note that this recommendation does not apply to any unofficial ports or forks, which may have higher CPU requirements). For better performance, the binary should be compiled for a 64-bit target(for example, x86_64) rather than 32-bit, if available.

Enabling CD image preloading into memory via the cd.image_memcache setting is recommended, to avoid short emulator pauses and audio pops due to waiting for disk accesses to complete when the emulated CD is accessed.

PSF1 playback is supported. However, many PSF1 rips won't work properly as they are broken in various ways:


Firmware/BIOS

Place the correct BIOS image files in the correct location. Do not rename other revisions/regions of the BIOS to match the expected filenames, or you'll likely cause emulation glitches(and cause confusion if you ever distribute or otherwise refer to these misnamed files).

The filenames listed below are per default psx.bios_* settings.

Analog Sticks Range Issues

The DualShock and Dual Analog controllers' analog sticks have a circular physical range of movement, but a much more squareish(corners are a bit rounded for DualShock) logical range, likely due to conservative calibration in the gamepads' hardware and firmware design. Modern PC(compatible) gamepads with a circular physical range of motion for their analog sticks(e.g. XBox 360 type controllers) tend to be more tightly-calibrated in hardware, and thus their logical range of motion will be closer to circles than squares. This can cause problems with movement in some PS1 games(e.g. "Mega Man Legends 2") that care not for proper trigonometry, as they are expecting larger values at ordinal angles of the sticks than the aforementioned type of PC gamepad can provide due to its design.

An "axis_scale" setting(named like "psx.input.port1.dualshock.axis_scale") is provided for each possible emulated DualShock and Dual Analog controller on each port. To work around this range issue with DualShock emulation, an "axis_scale" setting of "1.33" is recommended as a starting point. Smaller values(such as "1.20") may be sufficient and provide for more precise control, so try experimenting to find the ideal for your combination of gamepad and games.


Multitap Usage

By default, no multitap is enabled. Be aware that if you enable multitap on PSX port 1, game view mapping will be inconsistent between games that support multitap and those that do not.

Enabling multitap on either PSX port may cause slight game slowdown. Some 1-and-2-player-only games half-support the multitap, but are apparently not coded with the multitap in mind, and may suffer from graphical glitches like screen tearing if multitap is enabled when running them.

Settings Reference

Caution: Any settings that change emulation behavior as seen from the emulated game are shown with the setting name bolded in the table. One should be conscious of these settings if one has changed them from the default values when using network play or movies, as they can cause desychronizations if not set the same among hosts(or between the recording emulator and the playing emulator).

When enabled, instead of the configured Analog mode toggle button for the emulated DualShock, use a combination of buttons held down for one emulated second to toggle it instead. The specific combination is controlled via the "psx.input.analog_mode_ct.compare" setting, which by default is Select, Start, and all four shoulder buttons.

    Namco's light gun; NPC-103.

  • justifier - Konami Justifier
    Konami's light gun; SLUH-00017. Rumored to be wrought of the coagulated rage of all who tried to shoot The Dog. If the game you want to play supports the "GunCon", you should use that instead. NOTE: Currently does not work properly when on any of ports 1B-1D and 2B-2D.

psx.spu.resamp_qualityinteger0 through 105SPU output resampler quality.

0 is lowest quality and CPU usage, 10 is highest quality and CPU usage. The resampler that this setting refers to is used for converting from 44.1KHz to the sampling rate of the host audio device Mednafen is using. Changing Mednafen's output rate, via the "sound.rate" setting, to "44100" may bypass the resampler, which can decrease CPU usage by Mednafen, and can increase or decrease audio quality, depending on various operating system and hardware factors.

psx.scanlinesinteger-100 through 1000Enable scanlines with specified opacity.

Opacity is specified in %; IE a value of "100" will give entirely black scanlines.

Negative values are the same as positive values for non-interlaced video, but for interlaced video will cause the scanlines to be overlaid over the previous(if the video.deinterlacer setting is set to "weave", the default) field's lines.

Obviously, this will only work with the OpenGL "video.driver" setting, and only on cards and OpenGL implementations that support shaders, otherwise you will get a black screen, or Mednafen may display an error message when starting up. When a shader is enabled, the ".videoip" setting is ignored.

  • none - None/Disabled

  • autoip - Auto Interpolation
    Will automatically interpolate on each axis if the corresponding effective scaling factor is not an integer.

  • autoipsharper - Sharper Auto Interpolation
    Same as "autoip", but when interpolation is done, it is done in a manner that will reduce blurriness if possible.

  • scale2x - Scale2x

  • sabr - SABR v3.0

  • ipsharper - Sharper bilinear interpolation.

  • ipxnoty - Linear interpolation on X axis only.

  • ipynotx - Linear interpolation on Y axis only.

  • ipxnotysharper - Sharper version of "ipxnoty".

  • ipynotxsharper - Sharper version of "ipynotx".

  • goat - Simple approximation of a color TV CRT look.
    Intended for fullscreen modes with a vertical resolution of around 1000 to 1500 pixels. Doesn't simulate halation and electron beam energy distribution nuances.

0Force interlaced video to be treated as progressive.

When disabled, the default, the "video.deinterlacer" setting is effectively ignored with respect to what appears on the screen. When enabled, it may be prudent to disable the scanlines effect controlled by the *.goat.slen setting, or else the scanline effect may look objectionable.

The destination rectangle is NOT altered by this setting, so if you have xscale and yscale set to "2", and try to use a 3x scaling filter like hq3x, the image is not going to look that great. The nearest-neighbor scalers are intended for use with bilinear interpolation enabled, at high resolutions(such as 1280x1024; nn2x(or nny2x) + bilinear interpolation + fullscreen stretching at this resolution looks quite nice).

  • aspect_int - Aspect Preserve + Integer Scale
    Full-screen stretch, same as "aspect" except that the equivalent xscalefs and yscalefs are rounded down to the nearest integer.

  • aspect_mult2 - Aspect Preserve + Integer Multiple-of-2 Scale
    Full-screen stretch, same as "aspect_int", but rounds down to the nearest multiple of 2.
