hlsl scan lines. Can't find any solid info on it! frustrating

[irthwirm]

I've search everywhere, youtube, forurms and there is no how to steps. Just the hlsl code you put in the meme.ini file which i've done with no results. Is there a program that does this for you. I'm using mameplus64 to create the mame.ini file. That's the only way I can seem to find a mame.ini file. It's in the root folder of the mameplus64. That's where mamepUI puts it. I have to be missing a step but again there is no solid walk throughs that I can find which is amazing to me since this a huge factor in improving the quality of a LCD screen emulation. Please help. Also can you apply these same affects to hyperspin or only the png images? Just to be consistent.

this is the code I'm trying to use

Some explanation http://gamingnos.blogspot.it/2011/10/quick-start-mame-hlsl-filter-guide-up.html

As far as I can remember mameplus does have a bug with hlsl, try to use mame UI or mame FX. Anyway the only reason to use mameplus is image filtering, not useful when using HLSL

Thanks. I'll give it a try!

Okay, it looked like I had to have Directx installed and then the hlsl code I put in the mame.ini worked. Super laggy so I'm going to try some other stuff. But the DirextX install is key. Not really mentioned anywhere. I just heard a couple of people vaguely mention it. But seems to be a key step.

I found these new settings online and they look freaking awesome. Except Mame becomes completely unplayable. Anyone have any insight? I have a i5 2500 at 3.3 ghz, 4 gigs of ram. I'm running off the onboard Graphics card. Not sure if that's the problem but from what I heard mame doesn't use the graphics card. Not sure if utilizing hlsl might change that though and I might have to get myself a graphics card or it's just metalling with some other settings.

Here are the settings for you mame.ini

Anyone looking for some good info on Hlsl needs to check out these threads. Hope this helps someone.

HLSL is the only mame feature to use videocard, actually hlsl is a videocard's shader. Intel's IGP can be a problem, it sucks in terms of features support and drivers. With my htpc i could not use HLSL before upgrading videocard from x1550 to 9800gtx

Also consider this:

hlsl_prescale_x 0

hlsl_prescale_y 0

yiq_enable 0

These are really "demanding" settings. Yiq is an overkill, dont' use it. Prescale on Y and X improves graphic but it can kill performance.

If you use "shadow_mask" consider this to avoid "moire" effect.

hlsl_snap_width 1920

hlsl_snap_height 1200

This must fit your screen resolution

shadow_mask_x_count 320

shadow_mask_y_count 240

This must fit the original resolution of the game you're running (yes, hlsl setting should be game-dependant).
