Sega Master System emulation in Mednafen is a low-priority system in terms of proactive maintenance and bugfixes.
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: |
|---|---|---|---|---|
| sms.fm | boolean | 0 1 | 1 | Enable FM sound emulation when playing domestic/Japan-region games. |
| sms.territory | enum | domestic export | export | System territory/region.
|
| Setting: | Value Type: | Possible Values: | Default Value: | Description: |
|---|---|---|---|---|
| sms.enable | boolean | 0 1 | 1 | Enable (automatic) usage of this module. |
| sms.forcemono | boolean | 0 1 | 0 | Force monophonic sound output. |
| sms.pixshader | enum | none autoip autoipsharper scale2x sabr ipsharper ipxnoty ipynotx ipxnotysharper ipynotxsharper | none | Enable specified OpenGL pixel shader. 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.
|
| sms.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. |
| sms.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).
|
| sms.stretch | enum | 0 full aspect aspect_int aspect_mult2 | aspect_mult2 | Stretch to fill screen.
|
| sms.tblur | boolean | 0 1 | 0 | Enable video temporal blur(50/50 previous/current frame by default). |
| sms.tblur.accum | boolean | 0 1 | 0 | Accumulate color data rather than discarding it. |
| sms.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. |
| sms.videoip | enum | 0 1 x y | 0 | Enable (bi)linear interpolation.
|
| sms.xres | integer | 0 through 65536 | 0 | Full-screen horizontal resolution. A value of "0" will cause the desktop horizontal resolution to be used. |
| sms.xscale | real | 0.01 through 256 | 3.000000 | Scaling factor for the X axis in windowed mode. |
| sms.xscalefs | real | 0.01 through 256 | 1.000000 | Scaling factor for the X axis in fullscreen mode. For this settings to have any effect, the " |
| sms.yres | integer | 0 through 65536 | 0 | Full-screen vertical resolution. A value of "0" will cause the desktop vertical resolution to be used. |
| sms.yscale | real | 0.01 through 256 | 3.000000 | Scaling factor for the Y axis in windowed mode. |
| sms.yscalefs | real | 0.01 through 256 | 1.000000 | Scaling factor for the Y axis in fullscreen mode. For this settings to have any effect, the " |
