I recently acquired a CIB 2600 adapter for my 5200.
I have tried using it on my 2-port 5200, but the console doesn't output any audio or video when the adapter is plugged in. When I remove the adapter and insert a 5200 cartridge, everything is working fine.
The seller says it was working on his 4-port 5200.
My 5200 is S-Video modded.
Any ideas on what could be wrong? Would the S-Video mod make my console incompatible?
