If this message keeps appearing, please contact Nintendo Consumer Service." when the .pkm file is a storage file. It must be a party file in order to work properly (issue is that storage files are 136bytes while party once are 236bytes). Original post text: Odd that no one is curious, but I am so here I go! Basically the game talks to Nintendo and the global trade center, but I wonder if we can get some of that data from external tools. I am pretty sure the official GTC flash site also reads from here, anyway I found out the URL addresses by hex searching in the rom file (platinum), here are the results: http://gamestats2.gs.nintendowifi.net/pokemondpds/common/setProfile.asp http://gamestats2.gs.nintendowifi.net/pokemondpds/worldexchange/post.asp http://gamestats2.gs.nintendowifi.net/pokemondpds/worldexchange/post_finish.asp http://gamestats2.gs.nintendowifi.net/pokemondpds/worldexchange/get.asp http://gamestats2.gs.nintendowifi.net/pokemondpds/worldexchange/result.asp http://gamestats2.gs.nintendowifi.net/pokemondpds/worldexchange/delete.asp http://gamestats2.gs.nintendowifi.net/pokemondpds/worldexchange/return.asp http://gamestats2.gs.nintendowifi.net/pokemondpds/worldexchange/search.asp http://gamestats2.gs.nintendowifi.net/pokemondpds/worldexchange/exchange.asp http://gamestats2.gs.nintendowifi.net/pokemondpds/worldexchange/exchange_finish.asp http://gamestats2.gs.nintendowifi.net/pokemondpds/worldexchange/info.asp http://gamestats2.gs.nintendowifi.net/pokemondpds/battletower/roomnum.asp http://gamestats2.gs.nintendowifi.net/pokemondpds/battletower/download.asp http://gamestats2.gs.nintendowifi.net/pokemondpds/battletower/upload.asp http://gamestats2.gs.nintendowifi.net/pokemondpds/battletower/info.asp Obviously one is the battletower and other is the trade. Now it seems to operate on GET and POST, since I found a lot of HTTP headers. They also set a User-Agent that I think is called "GameSpyHTTP" (but might be a variable name or refrence, as I also saw "User-Agent: HTTP_X_GAMECD" a line or two above. Anyway it is possible to get information of trades and pokemons available using external tools, thus you may create a "alert me when X is available" tool if you like, or filter out those "I want a Mew for a Mew" people that are just annoying. Any thoughts or information you have learned?
