## Introduction

The "pce_fast" emulation module is an experimental alternative to the pce emulation module. It is a fork of 0.8.x modified for speed at the expense of (usually) unneeded accuracy(this compares to the "pce" module, which traded speed away in favor of accuracy).

To use this module rather than the "pce" module, you must either set the "pce.enable" setting to "0", or pass "-force_module pce_fast" to Mednafen each time it is invoked.

WARNING: Save states, movies, and netplay are definitely not compatible between the "pce" module and the "pce_fast" module.

## Custom Palettes

Global Filename: | Description:
--- | ---
pce_fast.pal | PCE/TG16 9-bit GRB. If only 512 triplets are present, the remaining 512 greyscale colors will be calculated automatically. 512 or 1024 RGB triplets

## 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).

Setting: | Value Type: | Possible Values: | Default Value: | Description:
--- | --- | --- | --- | ---
pce_fast.adpcmlp | boolean | 0 1 | 0 | Enable dynamic ADPCM lowpass filter.
pce_fast.adpcmvolume | integer | 0 through 200 | 100 | ADPCM volume.
pce_fast.arcadecard | boolean | 0 1 | 1 | Enable Arcade Card emulation.
pce_fast.cdbios | string |  | syscard3.pce | Path to the CD BIOS
pce_fast.cddavolume | integer | 0 through 200 | 100 | CD-DA volume.
pce_fast.cdpsgvolume | integer | 0 through 200 | 100 | PSG volume when playing a CD game.
pce_fast.cdspeed | integer | 1 through 100 | 1 | CD-ROM data transfer speed multiplier.
pce_fast.correct_aspect | boolean | 0 1 | 1 | Correct the aspect ratio.
pce_fast.disable_softreset | boolean | 0 1 | 0 | If set, when RUN+SEL are pressed simultaneously, disable both buttons temporarily.
pce_fast.forcesgx | boolean | 0 1 | 0 | Force SuperGrafx emulation.
pce_fast.input.port1 | enum | none gamepad mouse | gamepad | Input device for Port 1 none - none gamepad - Gamepad mouse - Mouse
pce_fast.input.port2 | enum | none gamepad mouse | gamepad | Input device for Port 2 none - none gamepad - Gamepad mouse - Mouse
pce_fast.input.port3 | enum | none gamepad mouse | gamepad | Input device for Port 3 none - none gamepad - Gamepad mouse - Mouse
pce_fast.input.port4 | enum | none gamepad mouse | gamepad | Input device for Port 4 none - none gamepad - Gamepad mouse - Mouse

pce_fast.mouse_sensitivity | real | through | 0.50 | Mouse sensitivity.
pce_fast.nospritelimit | boolean | 0 1 | 0 | Remove 16-sprites-per-scanline hardware limit.
pce_fast.ocmultiplier | integer | 1 through 100 | 1 | CPU overclock multiplier.
pce_fast.slend | integer | 0 through 239 | 235 | Last rendered scanline.
pce_fast.slstart | integer | 0 through 239 | 4 | First rendered scanline.

Setting: | Value Type: | Possible Values: | Default Value: | Description:
--- | --- | --- | --- | ---
pce_fast.enable | boolean | 0 1 | 1 | Enable (automatic) usage of this module.
pce_fast.forcemono | boolean | 0 1 | 0 | Force monophonic sound output.
pce_fast.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. 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.
pce_fast.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 ".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 GPU-intensive. 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.
pce_fast.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. 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.
pce_fast.shader.goat.hdiv | real | -2.00 through 2.00 | 0.50 | Constant RGB horizontal divergence.
pce_fast.shader.goat.pat | enum | goatron borg slenderman | goatron | Mask pattern. goatron - Goatron Brightest. borg - Borg Darkest. slenderman - Slenderman Spookiest?
pce_fast.shader.goat.slen | boolean | 0 1 | 1 | Enable scanlines effect.
pce_fast.shader.goat.tp | real | 0.00 through 1.00 | 0.50 | Transparency of otherwise-opaque mask areas.
pce_fast.shader.goat.vdiv | real | -2.00 through 2.00 | 0.50 | Constant RGB vertical divergence.
pce_fast.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). none - None/Disabled hq2x - hq2x hq3x - hq3x hq4x - hq4x scale2x - scale2x scale3x - scale3x scale4x - scale4x 2xsai - 2xSaI super2xsai - Super 2xSaI supereagle - Super Eagle nn2x - Nearest-neighbor 2x nn3x - Nearest-neighbor 3x nn4x - Nearest-neighbor 4x nny2x - Nearest-neighbor 2x, y axis only nny3x - Nearest-neighbor 3x, y axis only nny4x - Nearest-neighbor 4x, y axis only
pce_fast.stretch | enum | 0 full aspect aspect_int aspect_mult2 | aspect_mult2 | Stretch to fill screen. 0 - Disabled full - Full 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.
pce_fast.tblur | boolean | 0 1 | 0 | Enable video temporal blur(50/50 previous/current frame by default).
pce_fast.tblur.accum | boolean | 0 1 | 0 | Accumulate color data rather than discarding it.
pce_fast.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.
pce_fast.videoip | enum | 0 1 x y | 1 | Enable (bi)linear interpolation. 0 - Disabled 1 - Bilinear x - Linear (X) Interpolation only on the X axis. y - Linear (Y) Interpolation only on the Y axis.
pce_fast.xres | integer | 0 through 65536 | 0 | Full-screen horizontal resolution. A value of "0" will cause the current desktop horizontal resolution to be used.
pce_fast.xscale | real | 0.01 through 256 | 3.000000 | Scaling factor for the X axis in windowed mode.
pce_fast.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 ".stretch" setting must be set to "0".
pce_fast.yres | integer | 0 through 65536 | 0 | Full-screen vertical resolution. A value of "0" will cause the current desktop vertical resolution to be used.
pce_fast.yscale | real | 0.01 through 256 | 3.000000 | Scaling factor for the Y axis in windowed mode.
pce_fast.yscalefs | real | 0.01 through 256 | 1.000000 | Scaling factor for the Y axis in fullscreen mode. For this setting to have any effect, the ".stretch" setting must be set to "0".
