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!
