HQ / NTSC Filter Crash

phylteredreality · Post by **phylteredreality** » Mon Jun 11, 2007 4:55 am

When I click either the HQ filter or the NTSC filter, ZSNES crashes out.

This happens with versions 1.51, 1.50 and 1.42, using an Nvidia 8600 GTS with both the latest drivers and an earlier set (not sure what version exactly).

Anyone have any suggestions as to what I could do to fix the problem?

try the latest beta video drivers? imho i always hear the direct draw support in the 8x00 video card drivers is lacking.

The latest XP beta drivers I can find are dated November 06. I don't think those are compatible with this series of cards.

dunno then, i had a look myself, and yea, seems vista is getting the royal treatment from the big companies at the moment =\

Both are software filters.. so it's either the video card drivers that sucks, or you have bad RAM or something.

Try disabling/reenabling DDraw+D3D and see if that helps.

Edit: Also, try rebooting your comp.

Hmm. I tried disabling DD and D3D. Guess my problems lies in my Ram or Drivers then. Neither are fixable at this point. Bummer

Strangely enough, I can enable NTSC and HQx Filters without any problems in the latest versions of VirtuaNes, Nestopia, and Snes9x, but that really doesn't help me out, because the former two are NES emulators and I'd rather not use the latter. I thought the information might possibly prove to be useful in some way though.

Are you using System or Video memory in e.g. Nestopia?

doesnt snes9x use direct 3d?

DDraw.

Both _seem_ to work fine. I'm not sure how I might test the system memory to see if it's the culprit.

I also tried a few games on Bsnes last night and I can use its HQ2x filter without any problems, but something about it doesn't look right.

Options --> Video --> Memory Pool (Video|System).

HQxx lags like hell on my computer if I use Video, but it's silky smooth when I use System.

Sorry, I didn't explain that. I've tried either option, and they both run smoothly in Nestopia.

What I meant was, I don't know how else I might test the system memory to see if it could be the problem regarding my ZSNES crashes.

Try Memtest86 (or the variations of this program).

does zsnes use a different version of direct draw to the other emulators mentioned?

There is no significance at all. BSNES like ZSNES can use DDraw7 for your reference.

I might have to find an alternative to memtest, as I'm lacking in the floppy drive department.

Oh, and thanks a lot for all your suggestions and time, everyone--this is quite the mind boggler.

Actually, bsnes uses Direct3D9 by default, so that one can turn off the linear filter upon resizing if they like. DD7 doesn't let you do that, sadly.

If you want to verify that the problem is DirectDraw7, go to bsnes->Settings->Configuration->Advanced and set "system.video" to "dd". Restart the emulator. If it's still working, DirectDraw isn't your problem.

Also, you're probably noticing the difference because bsnes defaults to both modifying the gamma and correcting the aspect ratio, making the output appear more like a TV.

You can turn off gamma correction in the Settings->Configuration->Raster Settings screen (click 'Standard Preset'), and you can turn off aspect ratio correction via unchecking Settings->Video Mode->Correct Aspect Ratio.

memtest86 is availible as a bootable cd image.

Hi --

I have had this same problem (tried 1.51 and 1.42) on my computer as well. Like you, I have a GeForce 8000 series card (8600GT), but I am running Windows XP x64 and the latest non-beta drivers (Forceware 158.22). I think the video problems are strictly driver related ... from what I hear, there are many undocumented application compatibility issues that exist within the current non-beta driver set (Neverwinter Nights failing to load, for instance). So, don't fret over it too much ... I wouldn't worry about memory issues or anything of that sort.

I had the same problem with XP and a 8800gts. I would crash the second I activated the HQ filter. However, when I manually edited the Zsnesw.cfg file. It worked fine. Just edit the HQfilter section as such....

hqFilter=1
; Set HQ*x level [2..4]
; Recommended min resolutions
; HQ2x = 512x448
; HQ3x = 768x672
; HQ4x = 1024x896
hqFilterlevel=4

The only things you should have to change are hqFilter=1 and hqfilterlevel=4

I had the same problem (8800GTS on WinXP Pro 32), but jaa3rd's solution was an acceptable workaround. Hope you guys figure out where the problem lies in the next release.

No complaints otherwise.

franpa · Post by **franpa** » Sat Sep 29, 2007 11:45 pm

the problem lies in the video drivers >.<

phylteredreality · Post by **phylteredreality** » Wed Oct 24, 2007 8:52 am

By the way, I know it's been forever, but thanks again for responding. That workaround is just fine. I had suspected that the problem was in the drivers from the beginning, but hoped otherwise. *cries at nvidia's drivers*
