xBRZ... shaders for FS-UAE

[guest.r]

This "Dreamscape" shader is nice for folks who like smoothing/scaling shaders.
It was invented by a fellow emu fan shinra358 and i helped a bit with RA implementation.
This version is a bit different due shader framework differences.
----------------------------------------------------------------------------
Another version with different bloom added.

Some screenies:

Puh, sorry guest. Who would ever want to use such kind of filters in emulators? Maybe useful for art projects but surely not for gaming.

The CRT-Pvm-Lite update was nice though .

[guest.r]

Ehe, you are right with some games, it looks a bit strange with games like Rainbow Islands even when you are familiar with the effect.

But in my personal taste it looks very lovely in Lotus etc.. Such (smoothing/scaling) shaders prefer some games more some less. Same category as Super xBR or NNEDI.

Woudn't use these for a large group of Amiga games, true.

I have tweaked a bit more and the produced versions are more optimised for a larger variety of games.
Please download new versions below.

[guest.r]

Well, i've been contemplating my old TV again and discovered it's producing some kinky color aberrations.

I tried to emulate it and it's a quite similar thing.

I'm also quite a fan of CRT Lottes, since it also has many tweakable options and i modified it with the tv-colors stuff.

[Retro-Nerd]

Nice one too.

That's looking close to what I'm after, which adjustments did you make?

[turrican3]

not bad at all but i use to prefer this : but perhaps a little scanline or something like that could be better for others. But without scanlines i found
the result pretty good. My goal is always to try to make it look like the same game with a better resolution.
filters used : 1: 5xbr-v3.8c 2: AASF1 3: GS2xsmartfilter ... lores single (winuae) because this game is lores and single lines.
but if you monitor is more blurry than mine you can just keep filters 1 and 2 and on crt just 5xbr-v3.8c (i guess for the crt).

I added a horizontal edge scan for green/magenta tinting application.
On my TV surfaces leave green and magenta shades.

PVM shaders use theese tintings too, but in vertical direction.

@turrican3

If you want you can try some of the smoothing/scaling shaders for FS-UAE also. There are some like super-xbr, xbr-super, dreamscape.
I'm adding a nice ScaleFX - aa shader if you want to try it, similar to the screenie above.

It's an idea but i did a config file for each games is there a way to transfer them from winuae to fs-uae easily ?? are they
compatible ?

[guest.r]

They are not compatible. But for testing purpose you can easily create an A500/1MB profile.
I recommend using 1 floppy games for testing though.

[guest.r]

After a request for this nice shader i managed to port it to FS-UAE. It has many options, you can edit the #defines with Notepad++ and find your best setup.

For newcomers, create a Shaders folder inside of the Data folder of the FS-UAE directory and unpack the shader inside.

Then in the launcher, under Additional configuration (the cogwheel icon), enter the lines:

keep_aspect = 1.0
line_doubling = 0
low_resolution = 1
shader = crt-easymode-halation

Happyhats!

[guest.r]

I've updated the shader, it's a bit heavy, but should work better now i guess.

[guest.r]

As requested, Daum port too. (Dosbox).
Thankfully, it compiles the fast way.
I think retrofans will understand the OT.
I changed some (default) settings to show they are working.
To achieve the best effect please experiment in RA and then edit the #defines.

Edit: a mighty halation bugfix.

That fixed the warning and the error. But now there's another one:

0:49(1): error: syntax error, unexpected NEW_IDENTIFIER, expecting $end

[guest.r]

I think got this one too.
This one is configured a bit differently.

Hope it works now.

Edit: optimized for AMD Linux drivers

No, sorry. The nitpicky Mesa shader compiler is still complaining...

I re-uploaded the shader, can you test it again please?

Yeah, you did it. Now it works and it looks great. I lowered is the corner size a bit and now it looks perfect with lores forced and line doubling disabled.
I already liked this kind of shader in retroarch with libretro-fsuae core and now I can use it with fs-uae directly, many thanks.

[guest.r]

New sort of TV shader, a bit inspired with the popular ntsc effect.
Has many tweakable options...

Edit: some tweaks, looks nicer now.
