I own the Mother 2 cartridge and every code I try won't work besides two debug codes from this site: http://www.TheGSHI.org/?s=v2&sys=6&gid=719.
Has anyone created or knows about any other codes for Mother 2?
thanks!
P.S. I'm new and I haven't found a greetings topic anywhere.

as far as game genie goes, I can't help you, I even looked on google. and the only codes I could find where the ones that you said you have already done.
do the earthbound Game genie codes not work?

and the greetings page is is in the earthbound central discussion

Yes it is the Earthbound codes that don't work and the two on the link do work.
PS: there's differences been the mother 2 debug and the earthbound one quite a few actually I'd like to know if I should contact someone and who...

I don't really understand what you're trying to ask. but from what i think you're asking. I'd say ask somebody like Mato, he knows a lot on the topic of "differences in mother 2 and earthbound". heck he's dedicated a part of his website to the differences in mother 2 and earthbound.
