This page is for those with gameshark and pokemon. It is the largest archive of gameshark codes for pokemon that I've seen except Jdonald's faq, and The azure heights shark compendium which should be up soon.  There are many Gameshark codes for pokemon, and this section will list and explain them. They are, for the most part, for the Red, Blue Versions, and a few for the Yellow Version of the game.

Links and other stuff

To start off, here is how to convert Decimal to Hexidecimal:

Use Windows calculator. Hit View/Scientific, then look toward the upper left, and make sure "Dec" has a bubble next to it. Then enter your number in familiar base 10 (type in 1013). Now select "Hex". Poof! 3F5. Ok, now, here's how this works: Every byte has eight bits. A "nibble" is four bits. A nibble can be represented by a single hex digit (hex is base sixteen: because each it is also a power of two, it is easy to switch between that and binary). So if you want to write a byte, that's two consecutive hex values: 4A, for example. Let's look at 4A: 4=0100, A=1010, so 4A=01001010.

"F" is the biggest value that a hex value can have, so a byte's largest value is FF. Note that sometimes this is viewed as -1 (Ask me if you want to know about 2's complement notation: this stuff shouldn't be hard to find, though). This is why you would instantly die in Mario 1 using the 1Up trick (stomp the koopa, bounce on him) after a while: you had gone from 127 to 128, but the game viewed that as -128, and stupid things happened (I think)).

FF translates straight to decimal as 255. Add one to it, and it wraps around to 00=0. That's why 255 shows up as the max so often. For two bytes, its FFFF=65535, etc.

So 3F5 really is 03F5, or 03 F5 (two bytes). The most signifigant byte is the one on the left (like in the decimal value 153, the "1" is more signifigant than the other values, because changing that will have a greater effect than changing any others): So the most signifigant byte is 03,and the least signifigant byte is F5.

Genes

01FF86D1
01FF87D1

01??86D1 modifies the first byte: this contains the deter values for Attack and Defense. Each value is four bits, so the first hexadecimal value is Attack, the second Defense.

01??87D1 modifies the second byte, which contains Speed and Special (in that order). Same deal.

So where are hitpoints? The deter value for hitpoints is the combined Least Signfigant Bits of the other deter values in this order: Attack,Defense,Speed,Special.

Why? I don't know. So if your pokemon has the maximum attack and minimum defense possible, with regular values for speed and special, the bytes would look like this:

D186: D187:
11110000 10000111

Which would yield deter values of
Attack=>F (15)
Defense=>0 (0)
Speed=>8 (8)
Special=>7 (7)

Hit points are:
111*1*000*0* 100*0*011*1*
-->1001

MaxHP=>9 (9)

So if you use Gameshark now, you can instantly have a L100 pokemon with max stat EXP, and maximum possible genes.

While I wouldn't have a problem playing against someone who maxed out their stat EXP and their EXP (level) artificially, I wouldn't be pleased if they hacked themselves a perfect monster (a 1 in 65536 chance, by the way).

So the Mewtwo I was so pleased about catching has deter values of:
MHP :15
AT :9
DF :3
SPD :15
SPC :15

Stat Exp.

To attain Maximum stat exp in all categories, use these codes:

MHPH 01FE7CD1
MHPL 01017DD1
ATTH 01FE7ED1
ATTL 01017FD1
DEFH 01FE80D1
DEFL 010181D1
SPCH 01FE82D1
SPCL 010183D1
SPDH 01FE84D1
SPDL 010185D1

OT modifiers.

01XX59D3 High byte, trainer number
01XX5AD3 Low byte, trainer number

These codes are used to modify the trainer number of the actual file (not individual pokemon). If you change this number, all pokemon not matching the new number will gain 1.5 EXP, for instance. All new pokemon caught will be using the new number, and you can probably use this to fool Stadium, as well.

Leave GS switch off (after entering codes), start game, toggle GS switch On, then Off again, then save. It will tell you that the older file will be erased. This is because it is based on trainer number, which you just changed. Answer OK. Your Trainer number is now modified, with all the attendant penalties and bonuses.

01??77D1
01??78D1

Will modify the OT value of the top monster. This allows you to gain enhanced EXP with it, or change it to yours so that you can change the name.

 Names

Yellow:

01XX72D2
01XX73D2
01XX74D2
01XX75D2
01XX76D2
01XX77D2
01XX78D2

For Red/Blue:

01XX73D2
01XX74D2
01XX75D2
01XX76D2
01XX77D2
01XX78D2
01XX79D2

Now what you do is plug into the XX's the number that translates to the character in question. I'm ripping this chart off of:
http://www.angelfire.com/ok/EVOver2/index.html

Well, not actually *ripping*. I copied it over, found a bunch of errors in the lowercase stuff and corrected them. Either this chart is wrong, or the actual letter codes change whether you are dealing with monster names or trainer names (the codes given are said to modify monster names).

Here goes:

A 80 K 8A U 94 [ 9E i A8 s B2 l BC
B 81 L 8B V 95 ] 9F j A9 t B3 s BD
C 82 M 8C W 96 a A0 k AA u B4 t BE
D 83 N 8D X 97 b A1 l AB v B5 v BF
E 84 O 8E Y 98 c A2 m AC w B6
F 85 P 8F Z 99 d A3 n AD x B7
G 86 Q 90 ( 9A e A4 o AE y B8
H 87 R 91 ) 9B f A5 p AF z B9
I 88 S 92 : 9C g A6 q B0 e BA
J 89 T 93 ; 9D h A7 r B1 d BB

C0-DF all look like a space, might try them if Stadium is changing your space to null (or something).

' E0
Pk E1
Mn E2
- E3
'r E4
m (?) E5
? E6
! E7
. E8
??? E9 (looks foreign)
??? EA (looks foreign)
??? EB (same deal)
|> EC (open triangle)
|> ED (filled triangle)
EE (filled triangle points down)
Mars EF
Pk-Yen F0 (money symbol in game)
Odd X F1 (from title screen)
. F2
/ F3 (for accessing files on Bill's PC)
, F4
Venus F5
0 F6
1 F7
2 F8
3 F9
4 FA
5 FB
6 FC
7 FD
8 FE
9 FF

(F3 was a joke, assuming Bill runs Unix)

*Note: all lowercase letters AFTER lowercase z are actualy prefaced with tilde or some kind of foreign accent. English character only? Why?

I'm not sure, but I think when you want a name to end you put a 00. Once again, I am not certain of this, and I would certainly test it. It is possible that this is what Stadium does to names: replace the space with a Null character (the zero character, probably the EOS character here).

So if you wanted Cfalc as your OT for the pokemon in the first slot, you would use: (On Red/Blue):

018273D2
01A574D2
01A075D2
01AB76D2
01A277D2
010078D2

Good Misc Codes

To catch pokemon at any level in the wild, use this code:

Pokemon you encounter are at lvl 100 when you catch them:
016427D1

To catch them at level 50 for DV comparing:
013227D1

Basically, the code is:

01??27D1

and insert the level by changing the level number to a hex value *in first explanation at top of page*.

Clear the Hall of Fame:

Yellow:
0100A1D5
Red/Blue:
0100A2D5

Catch Pokemon with Max stats in the wild:

01FFF1CF
01FFF2CF

Have wild pokemon always have a certain status change:

01**18D0

00 = None, 01 = Sleep, 10 = BURN, and you'll have to mess around with it to see other status changes.

Change a Pokemon pictures

01??64d1- ?? = the pokemon's picture you want the poke to have.

Change a Pokemon's Types:

Type 1 Type2
01??70d1 01??71d1

Nor-00
fire-14
water-15
ele-17
gras-16
Ice-19
fit-01
Posi-03
Gro-04
Fly-02
Psy-18
Bug-07
rock-05
Gho-08
Dra-A1

Oh yeah, and one last set of codes:
011379D1
01127AD1
01D07BD1

Enter those codes in after you put the poke you want at lvl 100 in the first position, pulse it in, go into a battle vs anything and beat it, and your poke will grow to level 100.(It might grow to over lvl 100, if it does, just battle again, and it will go to lvl 100).

Back to top

From the r/b versions over to the yellow version of the game.

All codes on this page are for the r/b versions unless specified as for yellow.

So, if you have the yellow version of the game, and need codes for it, do this, simply subtract 1 from the sixth digit of the codes.

eg:

For Red/Blue:
01XX73D2
