i wondered if i used a code would all my mr1 saves be effected

As long as you do not save the game with the codes in play (or with their effects already in play, even if the code is turned off), then you won't have it recorded on any file. If you do save, then that file will have the sharked info but the others won't.

BTW, just a warning: Lisa and the other mods tend to have some antipathy towards these kind of questions. Be careful about asking them, especially with general names like "Gameshark question," or they might boot you or delete your post. Note that I'm still answering pretty much every "look it up on the board" question that I get sent to my personal email, so if you're worried that a question would bring the mods down on you, just send it to me. I have more patience than I probably should.

Actually, we are not antipathetic to Gameshark codes questions. If we were, we wouldn't have a section in the MR1 archive devoted to them. We simply don't tolerate 'Sharked' monsters in the Tournaments.

I didn't mean about sharking, I meant overly-general question titles.

Just a small note about Gamesharks though...maybe
it won't mess up a saved file, but it can mess the
game itself up. My friend used a Shark to gain
access to all the Dragon pages, but now, I can't
access any of my dragons at all. It just freezes.
This, for some reason, can be by-passed by using a
PS1, but the PSX and PS2 just freezes. (The
bouncing Pixie suddenly stopping is never a good
thing.)

MR1 doesn't work well with GS codes. The only one I ever felt safe using and saving with was the money code.

Welcome back, Tararara!! whispers "You do realise that you are replying to a month old post that replied to 4 month old (at the time) posts?"

I'm probably not the only person who looks up ancient posts for useful info :-P But actually, I didn't see the dates (though now I know that I'm replying to an ancient topic!)

Sorry about posting in an ancient, 2 and a half year old topic, but I just wanted to say:

The Gameshark edits specific parts of RAM. Now, we don't know everything about the game; we never will. We don't have the source code. So if you use a code, be extremely careful with what it does. If it is used to edit something like stats, only that game will be affected. But if you do something like cheating to unlock something, it has a very real possibility of messing up or even completely corrupting the game. So be careful!
