Hi there

I'm having an issue using my Popolon Sound Cart on my Omega. I can use the memory expansion fine, and scrom works for ROM uploading. But I can't hear any SCC audio at all. Does this cart require the 12v lines maybe?

Has anyone got this combo working with the stock Omega build?

Thanks for any help anyone can give ????

I can confirm it. Needs +5v, +12v and -12v

Ah, ok, that explains it. I'll get a 12v converter attached. Thanks for confirming

You need -12v too.

Heya

Yeah, I've just added +12 and -12 to the cartridge connector and it all works great now.

Thanks for the assistance
