You know when your playing a game save and then turn it off and when you turn it back on it says "Save File Corrupted" or your son/daughter,cousin ,friend,relative accidentally erase your file on your game if that has post a reply.
that only happened to me once on my DS when i was playing Digimon, it got corrupted because i accidently hit my DS on my knee while getting up... then the game froze and i lost the data
i was on lvl 99 with Latios,Latias,Kiogre,Groudon,Celebi and Jirashi, i was saving and then it hit the corner of my bed and you know what happens next
Happens for me after way to much cheating, but never if the DS falls or something like that... I swear, every single little game console I have must be at the point of immortality...
not so much save file corruption but accidental erasings, I was up to the final level in secret of evermore on the snes the space station level when my cousins came over they wanted to have a turn and when they went to save their game I did it for them and saved over the top of my own save file by accident I have never played the game again since that day it was almost 12 years ago, I had wario ware touched on the ds one of the first games I bought for it I let my nephew play it for 10 mins he erased my file with about 60 hours of play time again I have not played the game since that day.
150 stars on super mario 64 ds........... and then the save file got corrupted..... good thing i kept a backup on my computer ;D
completed FFVII: Crisis Core for the third time (since FFVII:CC lets you start the game again using the same save file and continue with all of your stats,ect.) also had 100% on about 13-14 other rather long hard games for PSP, then used my memory card in my camera for uni and hit format card without thinking to clear all the photos before using it on my PSP again. Guttered.
