CRT Curvature simulation. - Page 2

I'll say it again, I'd love to see a Stella-like TV CRT simulation effect.

Indeed, it doesn't (yet) simulate curvature, but that could be added later.

...well, I'm sorry for the HUGE pic, but it has to be 1:1 otherwise you can't see the differences.

(wait 2 secs for the pic to change between ON and OFF)

My Amiga days were all played on horribly big CRT TVs, and an image like this was the norm

Very cool screen shot jbenam. I dont know if that filter have this problem, but the PAL filter of WinUAE draws "color bands" in high resolution pictures with copper rainbow effects that make it looks very poor in quality (a bit like in very old VHS). Thats the only thing in the PAL filter I dont like or dont want to see anymore in WinUAE.

Maybe that filter would be a good improvement to the filter system of WinUAE, to replace the VICE PAL filter. Looking at the filter panel of Stella, it looks to be very complete and maybe should be possible to emulate a NTSC display with it.

A filter doesnt have the be very realistic to be fun, and it would be impossible for the WinUAE community to build a such filter from scratch. But most emulators like MAME and SNes9X have this feature, one way or another.

There are people that doesnt like this effect but it is really a success in all emulators that it is implemented. Maybe its not the right time to implement it now, and would make the WinUAE core programming more difficult, but this is another history...

This looks kinda authentic. It's from a freeware PC game: http://www.piratehearts.com/blog/gam...-win-the-game/

I remeber some less-known NES emulator have similar effect.

It's funny. The majority of people using real hardware for their retro system fix tend to want to remove themselves from some of these sorts of annoying legacy things (I detest my 1084s monitor), while a lot of people using emulation want to recreate them

However, I LOVE my Philips CM 8833 monitor...

Yeah, I don't get it either. Why not get the real thing? It's not THAT much of a bother.

That said, I heavily doubt you have any basis for your 'majority' thrown-in statistic

Anyway.

1084s in 32" would be a dream come true for me. As it is, my 32" TV looks great

Bit different intensities, tiny cable-shadow, but.

For shed loads of reasons.

Emulation is free, instant, and infinitely more flexible. There's 3 reasons for ya

The context was being retro enough to want CRT emulation. If you want the curvature, and the glare too, why not go the last 10 yards and have a CRT at home for console/computer needs?

ps. So kgwhdload f.ex. isn't instant, free and flexible?

I think they are strange reasons anyway. Most emulation solutions allow people to just plop a bunch of the games onto a card and use it on the real thing. That difference is not very big at all to me.

It's more convenient. That's all. Unless you have a TV with 2-3 consoles plugged into it, then it's more convenient to insert a game off the shelf, on button, and grab the controller. I have a NES 8-bit, a CD32, and an A1200-060 with WHDLoad connected to mine.

But some parts of CRT emulation would perhaps counter the "original colors on 1000:1 contrast ratio LED screens" effect -- with no pillow shaped pixels and no scanlines, the lores picture blown up looks extremely sharply pixelated, and also the color dynamics are out of the window, so any subtle reds look like toy store advert text. That's, for me, is where it would be awesome.

Ah sorry! Thought you were talking about getting a real Amiga

Nobody wants anything as big as a CRT anymore!

kgwhdload may be instant, free and flexible, but if you don't own an Amiga you can't download one over the internet

Sure they do, they get even bigger ones like a 50" flatscreen... and then put it 10 paces away from the sofa.

Anyway, I have a 32" CRT, and if I could get a bigger one I would. So that's one at least.

It is if you've got barely some space for a single A1200 on your desk

I can't seriously imagine where I would put a behemoth like a CRT on this uber-busy desk

Photon · 21 November 2012, 18:54

Do you mean that you have some sort of monitor switch to a shared PC TFT?

Because I can understand that fitting more than one computer (well, keyboard) on one desk is tricky (due to TFTs having roughly the same size foot, but being wider). It's also not a very good idea.

There are all sorts of imaginative solutions, like getting another desk or one of those computer tables for your Amiga (or PC). Imagine all the extra desk real estate that could be cluttered up in no time
