In the original Zelda: Link's Awakening, there was this sick glitch that let you walk through almost any wall if you pressed select while entering a doorway. This would bringp the map and when you exited, you'd be on top of the wall at the other side of the room yu were entering. You could hop down from there and end up in another part of the map, or another map entirely. You could really fuck your game up like this if you end up in the wrong place I also noticed this got fixed in the GBC version of the game.

Might not be a glitch at all. Could actually be some sort of secret... I can't imagine how a glitch would create a glowing ball of light.

well...okay. here is absolutly everything that makes Missingno. and the infinite items glitch tick. By reading this, you can probably find a way to make it so the player can't do these things to make missingno appear.

For most variables on Game Boy games, the fewest possibilities for the variable is 256 (HEX 100), labeled 0 to 255 (HEX 00 to FF). This goes for most variables in RBY, including ones for all the Pokemon lookup slots. However, only 151 Pokemon exist in RBY. So, if there are 256 possibilities, and only 151 slots were defined by the programmers, what do the other 105 slots have? Glitches. And so, Missingno. was created.

There are two things that, when combined, made it possible for this trick to exist. Here they are:

1. When creating the map for what Pokemon appear where, they made a crucial flaw. The 1-square-wide strip of water on the right side of Cinnabar and Seafoam Islands was programmed to be a place where wild Pokemon CAN appear. But (and thank GAMEFREAK for this one) they forgot to define what Pokemon can appear there. This wouldn't be that big of a deal, except that means the previous settings for "what Pokemon can appear" will remain, and if you read #2, you'll see why that causes the glitch.

2. When the Old Man catches the Weedle, they change the variables that are assigned to "Your Name" to Old Man, so it shows up as "Old Man threw the Poke Ball." Now, in order to do that, it overwrites the variables you gave to "Your Name". Therefore, the game must store the variables that make up your name to another place, so it can recall them later. So the programmers at NOA probably thought,
"What are some variables that we can overwrite to assign to the character's name for this process?"
"I got it! How about the slots that define what Pokemon you can run into?"
"That's it! Whenever the character enters a new area, they'll be rewritten, so it won't disturb the game at all!"
*points to #1* Umm.....no. As a result, that wonderful glitch can be yours for only *insert whatever price your local retailer charges for R/B*! Of course, it's not JUST Missingno. you can run into. There will also be some L100+ Pokemon, whose species and levels are determined by your name.

First off, look at letters 2, 4, and 6 of your name. Those letters will determine the levels of the Pokemon you can run into. First, take the NUMERICAL equivalent (A=1, B=2, etc.) of those letters, and add 127 for uppercase or 159 for lowercase. In addition, the symbols are as follows:

( 154
) 155
: 156
; 157
[ 158
] 159
PK 209
MN 210
? 239
P(monetary symbol) 240
x(times sign) 241
. 242
? 245
Also, at the end of your name, the game inserts an 80 (HEX 50) to designate "End of Name". Because of how the variables are used, this means that one of the levels your Missingno. (or glitched 'M name) will be is always L80.

While it is determined by name, the lowest number assigned to a character (other than the 80 that is assigned to the "End of Name" character) is 128, for a capital A. In EVERY variable that designates a Pokemon, Mew is assigned the number 21 (HEX 15). If you can make the connection, that means that NO name you enter will result in Mew being a possibility. The low numbers like 21 represent glitch characters that are not available for naming anything and can only be found with a Shark. For convenience, here is the table of what Pokemon will appear for each letter. Letters 3, 5, and 7 are used to determine this:

A: Golduck
B: Hypno
C: Golbat
D: Mewtwo (BIG OPPORTUNITY HERE!)
E: Snorlax
F: Magikarp
G: Missingno.
H: Missingno.
I: Muk
J: Missingno.
K: Kingler
L: Cloyster
M: Missingno.
N: Electrode
O: Clefable
P: Weezing
Q: Persian
R: Marowak
S: Missingno.
T: Haunter
U: Abra
V: Alakazam
W: Pidgeotto
X: Pidgeot
Y: Starmie
Z: Bulbasaur (Get all the starters without trading!)
a: Missingno.
b: Missingno.
c: Missingno.
d: Ponyta
e: Rapidash
f: Rattata
g: Raticate
h: Nidorino
i: Nidorina
j: Geodude
k: Porygon
l: Aerodactyl
m: Missingno.
n: Magnemite
o: Missingno.
p: Missingno.
q: Charmander (Get all the starters without trading!)
r: Squirtle (Get all the starters without trading!)
s: Charmeleon
t: Wartortle
u: Charizard
v: Missingno.
w: Missingno.
x: Missingno.
y: Missingno.
z: Oddish

Note: If you want to try the glitch, DO NOT use one of the special characters in your name. If you do, you might end up facing a Trainer. You will not be able to get out of the match, and eventually one of their Pokemon will be a glitch that can freeze (and possibly erase) your game. Also, species from 3 goes with level from 2, species from 5 goes with level from 4, and species from 7 goes with level from 6.

example

Test #1- Name: PIKACHU
Letters 2, 4, and 6 (levels):
2: I = 9 + 127 = 136
4: A = 1 + 127 = 128
6: H = 8 + 127 = 135
Letters 3, 5, and 7 (species):
3: K = Kingler on chart
5: C = Golbat on chart
7: U = Abra on chart
Combining the numbers, the name

Eh? The door is the same door that's on the "true" side. It can be activated from both sides, y'see.

Ok!

Anyone remember that strange bug in Zelda II? There is one town later on in the game, you have to go through some mountain stage to get there (don't remember the name). Now, walk to the second part of the town. Then, change yourself into a fairy and fly high in the sky. Now keep flying to the left. You'll see a part of a door in the sky, enter and you'll fall down like if you'd fall into a pit. You'll be in the town again, but the whole world be glitchy from now on, with strange people saying strange things and grass being water and that kinda stuff...

Eh, I thought it only could destroy the save RAM. Which can be fatal if it's screwed up in a strange way.
