Introduction
WARNING: Save states(and by extension, state rewinding and netplay) and saved games on emulated memory cards do not mix well unless you areextremely 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 forrunning Mednafen's PlayStation 1 emulation on(note that this recommendation does not apply to any unofficial ports or forks, which may have higherCPU requirements). For better performance, the binary should be compiled for a 64-bit target(for example, x86_64) rather than 32-bit, if available.
In other words the game is realy slow. Just 1 question, though. Is 5501 BIOS still missing? Emulation is all the rage in PC gaming. This is occurring only after applying the tweaks. Emulating games on PC usually means a full emulator and different program per platform, but RetroArch can actually emulate quite a large number of. The BIOS file begins at hex offset 54E08 and is hex 80000 bytes (512 KB) long. If done correctly, the extracted code should have Sony Computer Entertainment Inc at offset hex 108 and System ROM Version 4.5 at offset hex 7FF32.
Enabling CD image preloading into memory via the cd.image_memcache setting is recommended, toavoid 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:
- Contain malformed PS-EXE headers.
- Perform unaligned halfword and word memory accesses.
- Erroneously use load instruction target register as a source register in load delay slots.
- Set volume too high, leading to obnoxious clipping in the emulated SPU.
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 likelycause 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.

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).
psx.cd_sanity | boolean | 0 1 | 1 | Enable CD (image) sanity checks. Sanity checks are only performed on discs detected(via heuristics) to be PS1 discs. The checks primarily consist of ensuring that Q subchannel data is as expected for a typical commercially-released PS1 disc. |
psx.correct_aspect | boolean | 0 1 | 1 | Correct aspect ratio. Disabling aspect ratio correction with this setting should be considered a hack. |
psx.dbg_level | integer | 0 through 4 | 0 | Debug printf verbosity level. |
psx.h_overscan | boolean | 0 1 | 1 | Show horizontal overscan area. |
psx.input.analog_mode_ct | boolean | 0 1 | 0 | Enable analog mode combo-button alternate toggle. 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. |

|

psx.slendp | integer | 0 through 287 | 287 | Last displayed scanline in PAL mode. |
psx.slstart | integer | 0 through 239 | 0 | First displayed scanline in NTSC mode. |
psx.slstartp | integer | 0 through 287 | 0 | First displayed scanline in PAL mode. |
psx.spu.resamp_quality | integer | 0 through 10 | 5 | SPU 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.forcemono | boolean | 0 1 | 0 | Force monophonic sound output. |
psx.scanlines | integer | -100 through 100 | 0 | Enable scanlines with specified opacity. Opacity is specified in %; IE a value of '100' will give entirely black scanlines. |
psx.shader | enum | none autoip autoipsharper scale2x sabr ipsharper ipxnoty ipynotx ipxnotysharper ipynotxsharper goat | none | Enable specified OpenGL shader. 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 '
|
psx.shader.goat.fprog | boolean | 0 1 | 0 | Force 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, unless it's set to 'blend' or 'blend_rg'. 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. |
psx.shader.goat.hdiv | real | -2.00 through 2.00 | 0.50 | Constant RGB horizontal divergence. |
psx.shader.goat.pat | enum | goatron borg slenderman | goatron | Mask pattern.
|
psx.shader.goat.slen | boolean | 0 1 | 1 | Enable scanlines effect. |
psx.shader.goat.tp | real | 0.00 through 1.00 | 0.50 | Transparency of otherwise-opaque mask areas. |
psx.shader.goat.vdiv | real | -2.00 through 2.00 | 0.50 | Constant RGB vertical divergence. |
psx.special | enum | none hq2x hq3x hq4x scale2x scale3x scale4x 2xsai super2xsai supereagle nn2x nn3x nn4x nny2x nny3x nny4x | none | Enable specified special video scaler. 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).
|
psx.stretch | enum | 0 full aspect aspect_int aspect_mult2 | aspect_mult2 | Stretch to fill screen.
|
psx.tblur | boolean | 0 1 | 0 | Enable video temporal blur(50/50 previous/current frame by default). |
psx.tblur.accum | boolean | 0 1 | 0 | Accumulate color data rather than discarding it. |
psx.tblur.accum.amount | real | 0 through 100 | 50 | Blur amount in accumulation mode, specified in percentage of accumulation buffer to mix with the current frame. |
psx.videoip | enum | 0 1 x y | 1 | Enable (bi)linear interpolation.
|
psx.xres | integer | 0 through 65536 | 0 | Full-screen horizontal resolution. A value of '0' will cause the current desktop horizontal resolution to be used. |
psx.xscale | real | 0.01 through 256 | 3.000000 | Scaling factor for the X axis in windowed mode. |
psx.xscalefs | real | 0.01 through 256 | 1.000000 | Scaling factor for the X axis in fullscreen mode. For this setting to have any effect, the ' |
psx.yres | integer | 0 through 65536 | 0 | Full-screen vertical resolution. A value of '0' will cause the current desktop vertical resolution to be used. |
psx.yscale | real | 0.01 through 256 | 3.000000 | Scaling factor for the Y axis in windowed mode. |
