I think it is because the games send the data to others. (IE. you tell your friend how much ammo you have, and how much life you have, (as you can tell by the health meter)) so the other games disconnect with yours, as you have impossible ammo/life.
The reason these codes work on wifi, is because on wifi you just tell people when you die (so the life one is fine) and you don't send ammo data.
Flying doesn't work, because when you send your cordinates to others, they are impossible, so thier games get confused (aka disconect.)
On wifi, you send cordinates to others and yet it doesn't freeze. I
THINK this is because they made it so you can have impossible cords on wifi to cover lag. (This would be the only reason I can see........)
P.S. I have codes that work on wireless in my sub. They are in codes everyone gets. I made them work, by making the codes affect everyone. (IE If you use the infin ammo, the games don't freeze, because your friends game also has you having infinate ammo.)
*note for above*
You AND your friend(s) have this code in effect. And the bots won't matter for the ammo part, as they are bots.
Also, if you want say infinate life for you and your friend but
NOT bots, then it is easy to arrange. Just modify the code that makes everyone god.
Code:
a20da7ee 00000000
120da7ee 0000270f
120da7f0 0000270f
d2000000 00000000
a20db71e 00000000
120db71e 0000270f
120db720 0000270f
d2000000 00000000
a20dc64e 00000000
120dc64e 0000270f
120dc650 0000270f
d2000000 00000000
a20dd57e 00000000
120dd57e 0000270f
120dd580 0000270f
d2000000 00000000
Now, because bots are last, you can just remove the P3&P4 part, resulting in this.
Code:
a20da7ee 00000000
120da7ee 0000270f
120da7f0 0000270f
d2000000 00000000
a20db71e 00000000
120db71e 0000270f
120db720 0000270f
d2000000 00000000
You can also do the same thing to say only give your friend infin ammo. If he is P2, then both of you have to use this code
Code:
a20db71e 00000000
120db71e 0000270f
120db720 0000270f
d2000000 00000000
That is just the P2 part.
*note*
For these wireless codes, all players MUST have them on for the game to work, and ONLY the codes that will work on wireless.
