What are the risks of an action replay ds?

if you get a bad code, it'll freeze

I agree with the person above but I'm just gonna

list some advice:

good codes to use:

wild Pokemon modifier

all items (when completed game it is a safe code)

any toher cheat that doesn't sound risky.

100% catch rate

bad codes to use:

egg produce quickly (when no Pokemon is in the day care)

egg hatch fast (high risk of getting a bad egg)

walk through walls cheat (if you out of area)

catch trainers Pokemon

evs or stats higher then the maxinum

Pokemon can learn any move

codes off the internet (that don't work or do the worng thing eg. dark arceus)
