I just bought a Sega Genesis model 1 V6 , I opened it and....

Hello assemblers, I just bought a sega genesis model 1 (for the superior sound and that), I opened the console to see is a VA6, But what surprised me was that the console was modded! here are some pictures:










The thing is , I don't know what is the purpose of that mod (Only that the headphone port is screwed, it sounds very bad), can anyone give some advice?

Thanks!

 

This is a stereo mod I suppose.
The Genesis V1 outputs mono only on the back with the DIN-8, but the front outputs stereo.

What I don't understand is what is the pin the modder used. There's no free pins on the back for the stereo.

Edit: seems to be the Composite? I don't understand...

Is there any trace cut or pin lifted on the videochip (CXA1145) ?

 

You could replace the composite video pin at the AV socket with stereo. It'd just limit the system to RF, or raw sync RGB.

 

Thanks guys for your input, I just talked to a friend a told me that the "modder" was an Idiot , I will just undo the mod for the moment.
