Custom PPSSPP shaders

[jdgleaver]

I've updated my shader collection with a few more ports and such - this is probably the last of them now, so I'll stop spamming this thread...

You can get a copy of the final bundle here:
  ppsspp_shader_bundle.zip (Size: 42.23 KB / Downloads: 4894)

It contains my existing 'PSP Color' and 'zfast LCD' variants, plus the following new additions:

=== Bead ===

This is a port of the 'bead' shader from RetroArch, which turns each pixel into a round bead. The native PSP resolution is actually too high for this to work entirely as it should (unless you have a 4k+ display), but it still produces quite a nice clean, crisp result:

[Bead] / [Bead + PSP Color]

       

Notes:

- REQUIRES a rendering resolution of 1xPSP

- REQUIRES a display resolution of at least 1080p

- Runs at full speed on mid-range Android devices

=== Dot ===

This is a port of the 'dot' shader from RetroArch, which produces an LCD effect with a sort of cosy glow to it:

[Dot] / [Dot + PSP Color]

       

Notes:

- REQUIRES a rendering resolution of 1xPSP

- REQUIRES a display resolution of at least 1080p

- This is quite a 'heavy' shader, intended for Desktop use. I've included a 'mobile' version (for Android, as I have with all the shaders), but you'll struggle to run it at full speed unless you have a beastly device.

=== LCD3x ===

This is a port of the LCD3x shader from RetroArch.

NB: There is already a version of this in LunaMoo's superb shader collection, but it has a hard-coded 'scanline size' parameter which doesn't match the pitch of the PSP screen. This shader just fixes that one issue, and adds a 'PSP Color' variant.

[LCD3x] / [LCD3x + PSP Color]

       

Notes:

- REQUIRES a rendering resolution of 1xPSP

- Runs at full speed on mid-range Android devices

- Does *not* require a 1080p display! This shader produces decent results (i.e. no unbearable aliasing effects) at 1360x768, so it's quite good for potato laptops:

   

=== LCD1x Sharp ===

Personally, I don't like blurry shaders, and the the colour separation of LCD3x gives me a massive headache... so I made a 'tweaked' version that is 'sharp' and which omits the 3-band LCD colour effect:

[LCD1x Sharp] / [LCD1x Sharp + PSP Color]

       

Notes:

- REQUIRES a rendering resolution of 1xPSP

- Runs at full speed on mid-range Android devices

- As with the LCD3x shader, produces decent results at 1360x768:
