Trick with using PC CRT

 What really needs to be done... is to use software to simulate the pixel color mixing/bleeding on the fly.  Now that we have dual (and quad..) core pcs... it would be great to use that extra processor to do the image output.

There's no need to do this in hardware.  The MAME team is already doing some pretty cool things with the manipulation of the image.  Once we see affordable, super-high-resolution video display devices and hardware powerful enough to drive them, I have no doubt that the folks working on MAME at that time will have the algorithms available to truly simulate the old screens.  But there's not an awful lot more that can be done at this stage of the game.

Oh, and the lines are still a necessary element.  They don't have to be super pronounced, but they do need to be there.

 The Mame team is not really all that interested in such endeavors.    In
fact, at one point in time, they were about ready to remove the
current 'Effects' that are in there.

 I have doubts that anyone is ever going to release a 19" monitor that can
do resolution at the needed level of being able to duplicate the actual
shadow masks.    There is really no need for it.   Instead, they will simply phase
out smaller screens,  and produce all larger screens at Adequate resolutions.

 We all know that LCDs do not look well at non native resolutions.  And
most people dont want to use magnification glasses to view their windows
text.

 We also know there is a good market for authentic looking arcade monitors
on the cheap.    You can grab a 17" svga monitor at the thrift shop for
$10. (if you dont already have 2 or 3 lying around already)

 As for the lines...  well, Imop,  the lines just do not make the picture look
anywhere near authentic at all compared to color bleed and mixing.

 Also...  theres no reason to have to rely on resolution levels for effects.  One
can scale effects to fit the desired output resolution. (within reason)

 And finally... There are many other Emus such as console systems which
would also benefit from such a solution.   I think it would be a great seller -
If someone had the know-how to pull it off well...

RandyT:
Well, without the extra resolution, there is not much else that can be done. It's not technically possible with a fixed resolution screen.  And if you believe it is, I'd like to hear the approach you think can be taken.

And if the MAME team were "all about scrapping the current effects", they probably wouldn't have put all that effort into the current crop.  So it appears that they have changed their minds, if that was indeed the case.

re: scanlines not being enough and the need for more color bleed options/filters in MAME.

ZSNES and some other console emulators have a new-ish software filter (aptly titled NTSC) that adds lines and has adjustable effects for color bleed, etc.  I see no reason they can't be ported or coded from the ground up for MAME.

Holy crap man, you weren't kidding. I just hit up the zsnes site (first time since 1.41) and checked out NTSC... That filter is absolutely AMAZING. It does composite, S-Vid, and RGB (with a ton of variable filters) to a T. It was like being taken back through time... except on my 61" samsung LED DLP. It's a million times better than playing in HQ4x or any of the SAI filters.

Thanks a million for the heads up on that. I'll donate generously to any kind soul willing to port this filter to Mame  :applaud:
