SMS 2 AV mod struggle

Post by /markiiisystem »

so I ended up soldering each point and got it working but the thing is the "av mod" only works if the RF adaptor/switch is plugged into its port. It only outputs a video signal to the tv through the yellow rca ouput when the RF adaptor is plugged in... without it, sms doesnt even "boot'.
Like if i turned it on with just the rca yellow video output connected - wait 2 mins then plug in the rf adaptor the SEGA logo pops up and loads up alex kidd...
