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.
| 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 |
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.input.port1 | enum | none gamepad mouse | gamepad | Input device for Port 1
|
| pce_fast.input.port2 | enum | none gamepad mouse | gamepad | Input device for Port 2
|
| pce_fast.input.port3 | enum | none gamepad mouse | gamepad | Input device for Port 3
|
| pce_fast.input.port4 | enum | none gamepad mouse | gamepad | Input device for Port 4
|
| pce_fast.input.port5 | enum | none gamepad mouse | gamepad | Input device for Port 5
|
| 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. |
| 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 "pce_fast.videoip" setting is ignored.
|
| 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, unless it's set to "blend" or "blend_rg". When enabled, it may be prudent to disable the scanlines effect controlled by the "pce_fast.shader.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.
|
| 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, for a sharper image, though the "autoipsharper" shader may provide better results.
|
| pce_fast.stretch | enum | 0 full aspect aspect_int aspect_mult2 | aspect_mult2 | Stretch to fill screen.
|
| 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.
|
| 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 "pce_fast.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 "pce_fast.stretch" setting must be set to "0". |
