Ok, lots know about Bad Egg 或者 ? in a circle, two Advanced Generation glitches. Let's add one 更多 to the list: A glitch that had no name! I have startd to call this one L_93X1p, 或者 The Mauville freezer! Most are from too many cheat codes, I had none.
Strange chain of events
I just got 翠, 翡翠 a few days ago, I finished the first 2 gyms in 3 hours and Team Aqua was too weak. After getting to Slateport, I touched the game 盒式磁带, 墨盒 on accident and there was a horrible, scratchy noise and everything froze. According to TRsrockin.com this is called game freeze, as I thought it was. It happenend again while battleing Brendan (So I'm a guy and I play as a girl, what are 你 going to do about it?) and it happened again without touching anything, it unfroze the first time but the 秒 time it didn't. I was afraid it would crash but it didn't thankfully.
The real MissingNO
In Mauville, I was talking to the guy that gives 你 HM Rock Smash, I left the room for about 5 minutes, when I came back, the bad noise had returned along with a high pitched beeping sound, I tried to 移动 but it was no use. After reseting it, the Rayquaza on the main screen was just a blob of pixels, and where it 说 Pokemon, was another blob that resembeled A 或者 3TrainerPoke. Creepy. If 你 have had a Glitch in Emerald, I wanna try it, so put it in the comments.
