I want to thank all the contributors to this effort. I don't post a lot, but when I find something deserving of praise, I pop up, and this effort does require a goodly amount of praise. The shader code is greatly appreciated.

Found a nice Sony Trinitron overlay. Looks really good with CRT-Guest-Glow-Lores+RGB mask.

Nice pics. Could you post the new overlay in The Zone for us?

Funny, I found on that site a picture of my old TV that I usually had connected to my Amiga 500 in 1997!



Beyond that, I had also a bigger Philips TV 21" that had a incredible colorful image when connected to my Amiga 500 via composite line.

Sorry for posting twice.

These shaders are all very nice, but they look much cleaner and sharper than my 14" TV ever did. I wish someone would make a shader that recreated those, that would rock.

Thanks again for creating this shader, with some tweaking of the parameters for personal preference it looks really great (especially with the modified winuae.fx!).

I'm also finding a new advantage in that it's really fast. This is coming in very handy when using it on less powerful devices, while still giving a truthful CRT experience.

As such, I was wondering whether you could possibly port your CRT-Guest-Lo-Res.fx shader to Retroarch's OpenGL format?

On my portable setup I have some libretro cores that I can't run with any of the (good looking) CRT shaders, because they're too demanding and I'm really curious whether a port of your shader would run fast enough .

Hi guest.r
Nice filters. I like CRT-Guest-Hi-Res, is like an arcade machine. I make an autoload Host file called Arcade with this filter and use it with the DamienD´s pack, so i can bypass his graphics options (fullscreen, scanlines) with my own settings (1920x1080 fullwindow, superhires*). My question is: how i can modify the filter to see less scanlines?
*I use superhires instead hires because i see less blurry:

You can edit the h/v sharpness or scanlines strenght inside the CRT-Guest-Hi-Res.fx shader file. Just open it with a text edtior. btw: Lores and Line mode = Single looks best for Lo-Res games. Use CRT-Guest-Lo-Res.fx then.

Guys, this thread is just awesome ! Thanks to you all for this great work

I'm currently trying to run Pinball Dreams on a rotated CRT through WINUAE and my search ended in this thread

I would like to ask you all if it would be possible / doable to add some 90° / 180° / 270° rotation to any of these shaders (or is it already possible ?).

Thanks in advance for your help

Yea it's possible to add rotation to shaders, i guess 90 degree should do for start.
I'm adding this to a DDT-Sharp shader, which is basically a HQ version of linear filtering and looks much better.

If there are some special wishes about rotation/shader effect please let me know.

omg guest.r thank you so much ! I will test this asap and get back to you !

EDIT : I couldn't wait and tested it immediately ! It works very well, however as I suspected my rotation is of 270° (as most pincabs are) so my workbench is backwards lol

The same @270° and it will be just perfect !

EDIT 2 : Is it possible to have a specific "vertical" shader to use with it, as when it is rotated, it will appear "horizontal" ? I'm not sure I explain very well... old CRT were made to run games with no rotation so the horizontal scanlines are normal, now that we virtually rotate it, it needs a vertical scanlines becoming horizontal (normal) with the rotation...

Ok I think my second explaination is worse than the first one haha

Thanks again anyway

NP, it can be corrected.

The rotated crt shader needs a special mask to look OK though, since they are applied afterwards.

The scanlines will look horizontal on the rotated display i think that's what you are asking.

Having vertical scanlines is also possible...but it's a more demanding change.

guest.r : what you just did is incredible.

I know I may sound a bit hysterical on this, but I'm searching for a way to play these Amiga games on my rotated screen since weeks now, I tried tons of solutions, emulators, obscure old programs, quite frankly I gave up. I'm really glad I finally found that thread, what you just created is enough already

I'll finish my project and take some videos / screens so you understand better what I wanted to achieve, perhaps it'll give some ideas to other ppl as well.

My thanks again guest.r , you work is great an you're very kind !

EDIT : I didn't think that masks were applied "after" the shader so in fact the horizontal ones are ok : no need to create new ones

As you can see all is ok :

[IMG][/IMG]

I'm positionned on the right, so I see the image perfectly, and scanlines are horizontal

Hey, i'm glad it's working well and looking good.

If you want some more special shaders adapted, just tell...

I wish even less, that someone with Photoshop/GIMP skills would make a fullscreen "glare" overlay for using with the GuestCRT shaders and masks, but I think this could be hard to make, because no one have this idea.

You mean something like this?

This one looks nice: Grab it from the media fire link.

Yes, similar to that but with two differences: something without a photo of an ancient TV/Monitor (ie. only the "glare" part) but at the same time trying simulate a "rounded" CRT screen look.

The rounded look comes from the shader, i.e. CRT Geom. I don't use them anyway, hate the rounded look. Just posted some overlays i've found. Maybe a skilled EAB user can create something better for you.
