Would 120Hz work just as well for this?

Sure; so would 180 Hz and 240 Hz. <img src=smilies/magbiggrin.gif> Combine this with darkening the doubled scanlines to 75% or so and it looks very much like a TV (and for the record, a SNES on a TV looks fine). Doubling scanlines at 100% makes pixels way too blocky and crisp, unlike on a TV.

I recall seeing this pattern on SMW when I was young. Very nifty. ...and emulation continues to advance and impress.

I've released a beta of bsnes with the NTSC video filter.
There is a link to the file in this forum thread:
http://board.zsnes.com/phpBB2/viewtopic.php?t=6433

Please post feedback on the ZSNES board if you can, otherwise here should be fine.
Everyone be sure to thank blargg for this amazing filter!

SSE2?!
*kicks athlon XP chip*

would it be possible to make an SSE version, or is it a given that BSNES would not get a steady 60FPS on older, non-SSE2 processors?

This is really really nice.

I am getting a constant 61 fps on every game I try at 892x669. I unchecked Use Gamma Ramp (since it has no impact on NTSC) and am using NTSC with the hardware Pixel Filter (I think it looks better than Bilinear. You should add Bicubic.)

Just a note--on the progressive scanline intensity, it stops showing % values after 9%. Also, reset defaults does not restore its default value.

My specs are:

Intel Pentium M Dothan 2.00GHz
1GB RAM
ATI Mobility Radeon X600
Conexant AC-Link Audio

Just a note, bsnes starts to lag when I undervolt my processor, even though I'm not changing clock speeds ... rather odd. I have to kill out RM-Clock to run at full speed. I'll need to test-run bsnes for a few hours and see if it makes my PC overheat and boot-down like Nero does when operating at top speed.

Lastly, I really want to thank you for adding this. Without a filter like this, 98% of players could never see the Der Langrisser font the way I designed it to look ... (You remember how fucking long I spent making that font look perfect for televisions only to have it look WAY too narrow on emulators)

In our performance tests before adding the NTSC code to bsnes, SSE2 code generation hardly affect the speed; maybe it is important for something other than the NTSC filter. No matter, I've released the NTSC code so builds of other less-intensive SNES emulators should appear soon.

That's good, I'd like to be able to actually enjoy playing with the filter (No offense to BSNES or byuu, of course, I just don't have the hardware to run it)

Yeah, I heard Pagefault is going to be messing with it and we should see a WIP of ZSNES with it soon. <img src=smilies/cwm11.gif>

My apologies for the late reply.

I hate playing on my TV because there's always a sort of ghosting going around. It's not the system's fault; I assume it's due to the crappy RF signal I always got. While I enjoyed playing in my youth, these days those graphics are distracting. Maybe I'm just picky.

But I'm NOT saying that your work is worthless! On the contrary, I think it's amazing how you've managed to emulate how the system would look on a real TV screen. It's not my cup of tea, but I'm sure it'll be used by many people other than myself. Very good work. I hope you figure out a way to port the filter to other emulators.
