The SNS-RGB revision 1's all appear to have jailbars, at least all 3 of mine do, they're most noticeable when using RGB. The jailbars seem to be a result of the encoder. The SRGB 2 found on 1Chip Snes's including the mini's seems to have fixed the issue.

Thank you sir. EDIT: Found this on another board, posting here because it may be useful to someone else down the road: pin 1 is R/W_, goes direct to pin 34 of 2A03 CPU and pin 13 of IC 3G and pin 21 (WE) of IC 2K (2K x 8 bits SRAM / Work RAM) pin 2 is D0, goes direct to pin 9 of IC 2K ( WRAM) and pi...

Does anyone happen to have a pinout for this PPU? Thanks.

Pasky, PPU2 outputs the analog video signal. before that everything is digital. Your efforts do narrows things down though, thanks. PPU2 has a lot of pins, but isn't that complicated internally as far as digital logic. It does have a lot of multiplexers, shift registers, and the D/A converters, tho...

I don't think power droops are causing the lines, granted I only did PPU1 today, but I see absolutely no improvement in the picture using a separate regulator after the fuse and powering the ppu on it's own 5v rail. I've still got 2 very noticable vertical bars on my SFC, and unfortunately the jailb...

I've tried this before and noticed if a trace goes through a chip or something similar, it will not show any continuity. And ya, I don't have a nice multimeter that beeps when continuity is being tested, I'd really like one that had a fast response on the beep as well, I've seen some that beep, but ...

Ya I was, not exactly sure how to find vcc with continuity. Sometimes the resistance on the path is too high.

If I have time this weekend, I'm gonna install a 2nd regulator from where the power comes off the fuse and lift the ppu pins and power them directly...however, I'm having trouble identifying the pin numbers from the schematic: http://i.imgur.com/2XS6fLCl.png There's 4 per ppu, I know on PPU1, it's 1...

I realized that, you make it sound like that was some sort of revelation. I was merely trying exactly what TmEE did first to see if I got any noticable results before I decided to get into the more difficult work of lifting power pins on the ppu and powering it with its own power rail, as I don't wa...

Just tried adding ceramic caps on the vcc line for ppu1 and ppu2. Got no change on my sfc board which has 2 very noticable vertical bars. I then tried giving it 5v straight from the regulator in addition to the caps...No change at all.

=/

You will have to separate the analog bits, either by cutting traces (safer but more tedious) or lifting pins (hazardous). One you have severed connections you can feed your own supply to these pins. Could I simply lift the pins from both ppu's and the cpu and just wire them power straight from the ...

My potentiometer's arrived today, and I was able to dial in my SNES mini's rgb values today. I first took a lossless capture of my 1Chip snes, and captured about 12 minutes of footage of a still screen (the file select for super mario world) and adjusted the pots on my mini that I was live capturing...

I see thanks.

I'm unsure of any method to add an additional power rail, any suggestions? If not, I'll try putting some caps on those lines.

Bumping this back up because I'd like to revisit this. I recently acquired a SFC that has 2 vertical bars that are extremely noticeable. One in the center of the screen and the other on the far right. So this question keeps getting asked but never answered, but what lines need the extra power lines ...

Interesting, it's clearly sharper with the new encoder. I just bought 5 of those sony encoders and plan to install one of them in my SFC that has a really bad case of jailbars in RGB. I'll post a before and after video when complete.
