I'm looking around a few sites, and see that no one place has all the codes available. It's still necessary to go to multiple sources to find the codes you need. This got me thinking that perhaps we should have a GG code library, bringing all available codes together in a single source. We already have a few members here who know how to hack their own codes, and this would go well with the "Code of the Week" thing I suggested in the Batman Returns thread.
Opinions?
