If you read my last post, you'll find me giving shameless praise for Castlevania: Circle of the Moon.  I just found out today that all of my data for that game had been erased!  I was currently on my fifth run of the game (trying to beat it in "Thief" mode) and I was just about to beat it again too. 

Last night I decided to pick up another game for my GBA - Metroid: Zero Mission for less than $7.  I popped it in to my GBA to make sure it was working properly and it was.  So today, I'm thinking, "okay, I'll just quickly beat the rest of Castlevania and move on to Metroid."  I put the cartridge back in and my GBA showed a messed up Nintendo logo.  So I turned it off and on and stuck it back in and still nothing.  When it finally started working again, I had no saved data!  Argh!

I'll built all five of those characters up pretty high (level 60+) and everything I did in the past month or so is gone.  What a bummer.  I'm wondering if it was my GBA that messed it up or the cartridge?

I know that cartridges use batteries to save data, but the game isn't that old.  Right? 

Right......?
