My Radica sounds wierd.

I have the first version of the Radica sega doodad thing.

Some oddities!!!

The "FWWHOISH!" sound in the start sounds odd when I hit reset.

Most notable in games like sonic, the sound is distorted.

Also, the square wave, noise-sound generating PSG is very, very quiet. I can barely hear the jump sound and little bits of the music.

Anyone else's do this?

It's probably just due to the roughness of the sound encoder. If I remember, I had these problems too. Anyways, the Genesis uses a YM2612 (Yamaha) primary sound chip and a SN76489 (TI) secondary sound chip. You can imagine how lame the sound can become when all is packed in to one chip.

This is probably a long shot here, but do you visit TDC by any chance? If not... then whatever.

I knew that name was familiar! How did you find Benheck if you don't mind my asking?

Been looking around for a long time actually. I was googling around because I was really bored, and was looking for some way to portabalize my sega. Now, I didn't know about any Radica at that point, but when I bought one I thought, "HEY, I BOUGHT ONE!", but a more important thought would be "HEY! IT'S A TINY SEGA! YOU NEED A CARTRIDGE SLOT LITTLE BOY!" Except less... retarded...

After already doing this to my Atari 50-games-in-one native-hardware thing, I thought this would be cool to do.

Aw fudge, that's the second time that's happened, and I only clicked once!

Wow! That is what you call coincidence. Well I hope you enjoy this community as much as I do. I think you'll find that we're much friendlier here than at TDC.

BTW, you only need to click the 'submit' button once.

Thing is, I did only click it once.

Uh, does anyone have an answer about the radica unit though? (the PSG)

Still doesn't answer the fact that the PSG is nearly silent.

I'm not talking about distortion anymore.

Probably because the op-amp is damn weak. Install a second one.
