Ok I have A radica super sonic gold and I was wiring the cart slot with the diagram in the sticky.

I have wired everything exept for A21 and A22 wires to the rom chip Because if you look at the diagram there are no A21 and A22 pins on the rom cart, they are only on the cart slot.

Where do they go?

To my knowledge, no one has ever been able to get the Sega Sonic Gold radicas to work, I think the chip in those models had a completely different pinout. Sorry!

Hey, I too am working on a super sonic, I have wired a s&k cart to the rom chip for testing purposes and I am getting the black screen wich tells me that it should work after I figure out how to do the devster mod to it, now to your question, the best I know A21 and 22 don't hook to anything noone has ever answered me on this same question, its amazing how many people have made a radica work and yet no one will answer this one simple question, but try it without using 21 and 22 first thats the best I can tell you

Cool, i wired up my cart slot too and all i get is the black screen also.
And i need to figure out how to do the devster mod to it also.
I just don't know where to wire everything.

there is a sticky i think at the top of the board about radica mods and it has the devster mod in it the only problem is that the super sonic has a totally diffrent set-up on the HC174 than the normal radica, I am trying to figure out how to get it to work and should have some info pretty soon I will let you know what I find out
