About

This is a patch for TheFlow's Adrenaline v.6.7 for the Vita which adds a new graphics filter option called "Sharp bilinear without scanlines". The new option, when selected by the user, enables the sharp-bilinear-simple shader, which gives sharp pixels with minimum blur and zero pixelwobble regardless of scale factor. It doesn't cause slow-down like "Bilinear" does.

TheFlow has accepted this patch into his official codebase already, see commit # 49eb41a.

This patch is just for anyone who wants to use this new feature before it appears in the next official release of Adrenaline.

Installation

Adrenaline 6.7 must be installed already. To patch your Adrenaline, simply copy the file adrenaline_user.suprx to ux0:app/PSPEMUCFW/sce_module/ , overwriting the existing file.

In case something goes wrong, the original unpatched file is also provided, renamed to adrenaline_user_original.suprx

Recommended Settings

Smooth graphics have to be ON for the new option "Sharp bilinear without scanlines" to work correctly.

I recommend the following settings with this patch:

Handheld Vita:

Graphics filtering: Sharp bilinear without scanlines
Smooth graphics: On
Screen Scale X (PSP): 2.000 (or 1.995 if you like it blurry)
Screen Scale Y (PSP): 2.000 (or 1.995 if you like it blurry)
Screen Scale X (PS1): 1.135
Screen Scale Y (PS1): 1.135

VitaTV:

Graphics filtering: Sharp bilinear without scanlines
Smooth graphics: On
Screen Scale X (PSP): 2.000 (or 1.995 if you like it blurry)
Screen Scale Y (PSP): 2.000 (or 1.995 if you like it blurry)
Screen Scale X (PS1): 1.185
Screen Scale Y (PS1): 1.000 (I had a typo here before that said 1.100, it should be 1.000!)

Important note: If you still experience slow-down with these settings, just enter and exit the Adrenaline menu once, and the slow-down will disappear. This is a well-known issue with Adrenaline, independent of my patch.

Thanks

Thanks to my Patreon supporters: Andyways, Count_Duckula, Sean Ritzo, and all other supporters.

Thanks to @TheOfficialFloW for all his great work on the Vita.

Explanation

I noticed some screen tearing and slow-down using the "Bilinear" filter while playing Lomax PS1 in Adrenaline on my VitaTV. All the other filters work, but they look ugly with PS1 games.
I therefore added a new filter called "Sharp bilinear without scanlines"

This new filter enables the sharp-bilinear-simple shader, which gives sharp pixels with minimum blur and zero pixelwobble regardless of scale factor. This new filter setting also has no screen tearing and no slow down with PS1 games. For it to work correctly, "Smooth graphics" have to be turned on.
