Hey guys, thanks for the constant updates.
For someone who doesn’t own an SNES (and doesn’t really need the latency tester, atm), is it still worth updating? I feel like at this point I’m just waiting for the ‘fully adjustable scanlines’ feature – to see if it can improve in any way how they look on my 1080p monitor – and hopefully that ‘Horizontal mask’ bug fix too, so I’m not sure I want to wipe out all my profiles, if the new FW isn’t gonna change anything relevant to my retro setup.
Thanks again! ^_-October 31, 2017 at 11:11 PM #16635
Awesome, thanks Marqs!
For best results with SNES de-blur use reverse LPF in 256×240 optimized mode.
@marqs For the latency tester, is it ok to connect unused pins from the VGA connector to the BTN1 terminals so the light sensor can be connected through the VGA port? So that the sensor cable can be removed when not in use.November 1, 2017 at 1:12 AM #16641
Just tried out the reverse LPF setting on my regular old multi-chip Super Famicom and the results are amazing! Now much more on par with the kinda picture it get from my Mega Drive. Who needs a 1Chip eh?
Tested on Line3x mode at 256×240 optimised – I found 9 to be the sweet spot for me removes all noticeable signs of bleed

I have tried it, I think it looks worse, it just seem to replace the black pixels on the right to White.November 1, 2017 at 8:56 AM #16657
I assume this will be variable for each SNES because of different degrees of smear (variation in chip quality, other components, age etc). It didn’t work too great on mine either, not enough to make optimized mode useable anyway (going above 3 creates inverse (too light) pixels). It does slightly improve the situation in generic mode though, for me.November 1, 2017 at 9:27 AM #16659
Thanks for this! The reverse LPF has greatly improved my 2-chip SNES image in optimised mode. I initially had the issue with bright pixels when using too much reverse LPF. I found I needed to make the following tweaks:
Video LPF: Off
Analog sync LPF: 10Mhz
Analog sync Vth: 45mV
I’m guessing that these settings effectively move the horizontal sampling offset slightly in optimised mode. It’s enough that Reverse LPF setting of 3 can eliminate the effect almost completely, for my SNES at least.November 1, 2017 at 10:46 AM #16660
Here’s a before and after shot using the settings mentioned above. Really happy with the results!November 1, 2017 at 11:41 AM #16661
You shouldn’t need to change Analog sync options. You can get sync drop outs if you do. Setting reverse LPF to 3-4 and tweaking the sample phase should do it.November 1, 2017 at 12:23 PM #16662
Looks like you’re right paulb_nl, I was able to achieve the same effect with the default Sync LPF/Vth settings with only two changes.
Video LPF: Off
Sampling phase: 56 deg (was at 90 before)
It looks like the video LPF makes the blur worse on my end, no amount of sampling phase tweaking would give me clean edges with that enabled.

Right, I tried another SNES I have, and results are much better. As ptepid points out, default LPF kind of pulls in the wrong direction, but I found with LPF off there were too much noise and speckles, but the 35MHz (HDTV I) hit the sweet spot.
Really liking it now! 🙂November 1, 2017 at 11:52 PM #16694
@paulb_nl You may utilize unused VGA pins, assuming your VGA sources do not drive any signals into them.November 2, 2017 at 12:02 AM #16696
Thx for the info, am in joying the set up.November 2, 2017 at 12:05 AM #16697
Has anyone experienced any audio issues with the latest firmware? Since applying the update I’m getting no audio output at all with my 1.6 connected via Scart to HDMI to my TV.
Never mind! Genius here installed the wrong firmware version! Working now since using the -aud one!
