80s monochrome green phosphor displays

Thank you for this nice AQUA variant!

I only have a doubt on the shadow mask: I found out native monochrome tend to have plasma screens, so no mask at all. Later models shared screen components with classic shadow mask CRTs, so it’s not unusual to see monochrome screens with (useless) dot masks.

I think that a “pure” monochrome shader can just have a subtle scanline, just to add some organic depth, and stay clean to enjoy that blissful halation

yeah, I learned of this afterward. I assumed that all CRT configurations used some sort of shadow masks but yeah, it should be off. :+1:

BTW this is off topic but thanks for reminding me of this thread; it reminds me of last year’s holiday season :beers: :partying_face:

Mate, sorry about “resurrecting” this thread after such a long while… But I can’t find most of the parameters (“wrap_mode”, “mipmap_input”, “alias”, etc.) in RetroArch’s quick menu / shaders… Neither for gl/glcore (glsl) nor vulkan (slang) modes.

Are they core dependent? I’m currently trying the scummVM core. Any help would be appreciated.

Hi, so I think your best course of action would be to get the latest version of the Mega Bezel and adjust the parameters in the [ MONOCHROME ] section to make it green and adjust the hue and brightness.

The Mega Bezel is here HSM Mega Bezel Reflection Shader! - Feedback and Updates

The issues I’m having:

  • I don’t have that “Hyperspacemadness” folder inside bezel… here’s what my bezel shader folder looks like (after either updating it through RetroArch, or replacing it with your MegaBazel.zip folder:

  • Even if I use “stock” (he used 9) shaders (from c9f5fdda06’s December 2020) post, as soon as I hit “apply changes” for the first one (“grade.slang” shader), I get the message:

failed

Is all this GPU dependent? Meaning, is there a minimum requirement? What am I doing wrong?

So really with the Mega Bezel it is not recommended to make your own full presets.

What I would suggest is just load the glass preset from the Mega_Bezel/Presets folder and adjust the monochrome settings, then you can save your own simple preset which will have your parameter adjustments in it.

Do you remember what preset you used to generate this? Also, how do I get this running on my RetroArch?

Hi, this is now implemented in the included shaders. You can use the HSM shader under

\shaders\shaders_slang\bezel\Mega_Bezel\Presets

Pick a preset (*.slangp) and make changes to these parameters:

Monochrome Color 3
Monochrome Hue Offset 30

Here’s a simple preset:

#reference "shaders_slang/bezel/Mega_Bezel/Presets/MBZ__2__ADV-GLASS.slangp"
HSM_MONOCHROME_MODE = "3.000000"
HSM_MONOCHROME_HUE_OFFSET = "30.000000"
bloom = "1.000000"
halation = "0.150000"
gsl = "2.000000"
shadowMask = "-1.000000"

Save it as monochrome.slangp and save it to \shaders
