So ive been doing a dream team quest in my copy of sapphire and im on my 6th member (kyogre), however there is one problem, the battery has run dry and kyoger is a soft reset hunt. I thought i could just replace the battety it and keep going, but i read somewhere that replacing the battery isnt enough because the rng might still be messed up or something. Is this true and if so what can i do to fix this?
