Just bought an OSSC and a 1CHIP Snes. The OSSC works like a champ with my Genesis, no issues at all and everything looks great. The 1CHIP Snes works hooked up with component video straight to the TV. HOWEVER when i try and connect the 1CHIP to the OSSC via SCART I get a NO SYNC error every time. Hooked up my childhood 2CHIP Snes and it worked on the OSSC. Scart cable is the NTSC one from Retrogamingcables.com so it should be decent quality.
1. OSSC works just fine with Genesis
2. 1Chip Snes works just fine via component signal
3. OSSC works just fine with original 2CHIP Snes – OSSC works and SCART cable works, display is compatible
4. per the OSSC wiki, confirmed the following settings: H-PLL pre-coast: 1 , H-PLL post-coast: 0
5. Display is a computer monitor and the 2CHIP works – display compatible with signal
As far as i can tell its got to either be some additional setting in the OSSC or an internal issue with the RGB signal on my 1CHIP Snes. Anyone have any ideas on additional troubleshooting?
