[quote name='Neo Queen Serenity']As I stated in my second post. I already saw that there are Gameshark Lites and Gameshark CDXs on ebay. I bought a Gameshark Lite but my Dreamcast doesn't boot it up. I am looking for a Codebreaker or Action Replay, not a Gameshark.
Thanks for your help anyways.[/quote]
Hmm, from experience, if your Dreamcast cannot boot a gameshark, it will not boot any of the others either. There were no Action Replays back in those days. All cheating devices were made by Pelican or Datel. Datel was responsible for the then 'gameshark'. Hence, there's no Action Replay.
The codebreaker is essentially the same thing...I have them both, so I know.
Maybe it's time to dump that Dreamcast, and buy another.
