i dont really know wat fflash cart im using but the program is NO$GBA2.6a

Save issue most likely, read the thread linked above.

is not a problem of save issue it saves fine i think is a wifi thing since it supossed to activate when u go to the underground but ty anyways

You can't use wifi.

No, I don't think you need WiFi. More like local wireless.Anyway, the Underground works perfectly fine in Diamond and Pearl (yes, even though in all three games, the game says that the DS Wireless Communications will be launched and as far as I know, Nocash doesn't have wireless support), so I really don't know what's up with Platinum.I don't think its a problem with the save either, because the game did say that 'a communication error has occurred'. I'm using NO$GBA 2.6a, by the way, if that helps.

No$GBA does not support wifi in any shape or form, therefore it is not possible to do multiplayer using an emulator.

What I meant was, if Diamond and Pearl could allow me to access the Underground even though that would launch the DS Wireless Communications, why does Platinum give me a communication error instead? And how would I go about fixing that?By the way, the Underground, as far as I know, makes no use of WiFi. Just local wireless.

Just so you know, Local Wireless is "WiFi". WiFi is just a trademarked abbreviation of Wireless Fidelity, which means it can transmit data over wireless networks.

local wireless and wifi are the same thing. the only difference is one gets routed over the internet while the other does not. They both use the radio inside the DS, which no$ cannot emulate. The reason the roms behave differently is because the underground is coded differently. One tries to connect as soon as you access the underground, the other does not.

well ty for ur help guys but it looks like i wont be able to go underground to get some fossils oh well i guess ill just complete da game witout dem.
