PlayStation 1 emulation is currently in a buggy alpha state and not all hardware and features are emulated.
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. For better performance, the binary should be compiled for a 64-bit
target(for example, x86_64) rather than 32-bit, if available.
PSF1 playback is supported.
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.

If you're having trouble getting rumble to work on Linux, see if Mednafen is printing out error messages during startup regarding /dev/input/event*, and resolve the issue(s) as necessary.

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" will bypass the resampler, which will decrease CPU usage by Mednafen, and can increase or decrease audio quality, depending on various operating system and hardware factors. |

Obviously, this will only work with the OpenGL "video.driver" setting, and only on cards and OpenGL implementations that support pixel shaders, otherwise you will get a black screen, or Mednafen may display an error message when starting up. Bilinear interpolation is disabled with pixel shaders, and any interpolation, if present, will be noted in the description of each pixel shader.
Note: Mednafen's pixel shaders do not work properly on some AMD graphics cards(there is a diagonal line of distortion) for an unknown reason, possibly a hardware bug. - 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
GPU-intensive.
- ipsharper - Sharper bilinear interpolation.

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). - none - None/Disabled

Full-screen stretch, disregarding aspect ratio.
- aspect - Aspect Preserve
Full-screen stretch as far as the aspect ratio(in this sense, the equivalent xscalefs == yscalefs) can be maintained.
- 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.
