My 8 year old little brother (worst person ever, i hate his guts) pretty much ruined my Pikmin 2 save data. I was in the submerged castle sublevel 3 (day 20, 42+ hours playtime) and after taking away my wii and telling him NOT to play it i decided to play Pikmin 2, only to find that i was on sublevel 4 with 1 bulbmin and over 50 blue pikmin missing. I got really angry and instead of killing him, i decided to see if anyone in the world knows if its possible for me to go back to a previous save because i lost ALL of my blue pikmin and went from 50 pikmin dying since i started playing to over 100 deaths.
