Radica vs Genesis 3?

Post by neverused » Wed Aug 26, 2009 5:36 am

I was was wondering what the dimensions are for the Radica pcb and the Genesis 3 pcb. I know the Radica is smaller, but it does not have perfect compatibility with a cart slot, whereas the Genesis 3 seems to be quite a bit larger, but would not have compatibility issues...

Any help or suggestions would be appreciated.

Thanks!

The Genesis 3 has total compatibility once it is modded slightly to run with the 32X and SMS Converter.

The radica would use less power and is smaller, but adding the cart slot is very difficult. It seems only a handful of people have pulled it off.

The radica PCB is about 2 by 3.5 inches. There's a secondary PCB that you can probably do away with (just has the power and reset buttons, I think).

The Genesis 3 systems are not all that uncommon - I see them more often than mini SNES systems! The board is around 5 inches square, I think, but could be trimmed down more.

Well, if you plan on relocating the cart slot on the G3, it is a more straightforward mod than adding one to the Radica, but your soldering time ends up being about equal. As for compatibility, there is a mod for certain Radicas that make it compatible with Sonic and Knuckles. I don't know how much that mod improves the compatibility, though.

Thank you, that was what I was wondering.

Also, for future reference, I am referring to Genesis carts only for compatibility questions. Anything beyond that is just gravy.

Another question:

Can the Radica accept a 6 button controller or only the original 3 button? It may be a stupid question, but the thought occurred to me and I'd rather ask than learn the hard way.

The Radica cannot "accept" a standard controller per se - it uses 3.3v for its controllers, whereas the Genesis controllers demand 5v. You could, however, supply 5v to use a standard controller.

As far as 6 button controllers, one version of the Radica, the Street Fighter 2 edition, has two 6-button controllers. I don't recall if it contains extra wires (keeping a 1:1 button-to-wire ratio), or if it uses multiplexing (which the game would be expecting). I would suspect that it uses mulitplexing, but I can't say definitively. Additionally, the built-in controllers (obviously) do not have a button for switching between 3-button and 6-button setups, which means some games would not work.

As such, if you want to use a 6 button controller, I'd look to using the a standard Sega Genesis 6-button controller on the Radica - while a bit more difficult initially, it will give you much better results in the long run.

I was just working with a genesis 3, it was a 12x12cm square. You can probably trim, about about a half a centimeter off each side for an 11 x 11 square. Any more than that, and yours will end up like mine! :cry:

DevSter has a decent page of Radica info. It's not complete, but it does have a lot of good info.

There is a mod that involves lifting a few pins and rewiring them to play Sonic 3, Sonic and Knuckles, and Street Fighter. Supposedly, this also improves the Radica's overall compatibility. The version 1 (blue) Radica does not support 2-player gameplay at all. He also states that you need to get a 5V power source going to your cartridges, as the Radica has a 3.3V regulator and runs off that. It's a site definitely worth checking out.

Are there many games that require a 6 button controller? The only Street Fighter II version pf the Radica that I can find is ~$45 and I'm not going to pay that much for something I'll probably fry right away.

Mortal Kombat uses the X,Y, and Z for extra attacks. The Lost Vikings uses a few of them, but they can be replicated on a three-button controller. It's the only way to block on Cutthroat Island. Those are the ones I remember the best off the top of my head.

Honestly I've never come across a game that used them. They're typically only in fighting games so if your not a fighting game person you could probably make do without them...
