I have a video noise issue with my nesrgb. I’m using the Triad power adapter for my front loader nes, I’m using a csync cable from RGC.uk

I dont have vertical lines/jailbars, but I have video noise, and it’s especially visible on black background. I did not install this mod myself, but I do know how to solder, is there something specifically I need to examine and adjust from the rgb mod?

Thanks!

Just wanted to give my input on 0.84a. Using my 1CHIP-03, with voultars rgb board/lpf off, using euroscart cable (Luma as sync) *should i get a different cable since csync is restored from voultars board?*

Anyway, I’ve had zero sync issues with 0.84a. Games I’ve tested.

Star Fox 1 & 2
Super Mario World 1 & 2
Megaman X
Street Fighter II Turbo (1 & 2 player)
Super Metroid

These are the settings I’m using on the OSSC for 0.84a, everything else is default from when I flashed the 0.84a firmware to the OSSC.

Video in proc:
LPF 9MHz
B/Pb G/Y R/Pr gains = 50

Sync opt:
Analog sync LPF = 2.5MHz

Output opt:
Line5x mode = 256×240 optim.
240p/288p proc = Line5x

Sampling opt:
<Adv. timing> 256×240:
Sampling phase = 90
H. samplerate = 341.00

Thanks for responding marqs, yup pin 50 from the VDP has been cut. I originally tried generic 4:3 and loved how everything looked, but then I learned about optimal timings and I dont want to go back to generic 4:3, cause OT looks like an emulator with my snes/genesis! But if you’re telling my only option is to stick with generic 4:3 for genesis, I may just do so.

I love the OSSC, but I’m disliking the Genesis with it more and more, I own a model 1 which I csnt fully remove jailbars with bypass boards and smd capacitors, and then there’s the resolution changes throughout games. I dont want to purchase the Mega SG, because I want my model 1. My SNES 1CHIP-03 is the only console I’ve got looking magnificently with my OSSC. I figured since 240p/480i was able to swap via the OSSC, that what I’m asking would do the same. Thanks for the replies!

Hello I have a question regarding a bypass that I’ve done last year,using one of the first bypass amps released (its green and has 3 vertical capacitors)

My system is a model 1 VA6. My method I performed, was lifting the R,G,B,Csync pins from the VDP off of the motherboard, soldered cdrom audio cables from those pins, to the bypass amp. I also have pin 50 from the VDP cut.

The picture I get from my ossc with firebrandx’s 320×224 optimal timings is incredible!

With that said, I still have very very faint vertical lines,they are really noticeable on a light gray background, example being the hidden stage select screen for Altered Beast.

Now, i did this before Voultar released his version of the bypass. I have removed the 3 pull up resistors on the bottom of the motherboard, and I’m bypassing the CXA Sony chip entirely.

Why, when I’m running directly from the VDP, to the bypass amp, am I still getting vertical lines? What am I missing, or need restored?

I’m using a euroscart rgb cable wired for csync.

Please help, thanks!
