SegaXtreme

Hi everyone....I haven't posted here in ages but I have quick question.

I bought an X'eye on ebay for a really good price. Unfortunately, there was no ac adapter that came with the X'eye. I thought I could use the Sega Genesis power adapter but it was too big. Is there an alternative power adapter (maybe radio shack) that would have something that would work as a replacement power adapter for the X'eye? Or if anyone has an X'eye power adapter they could sell me (although rare) possibly?

Thanks
