Ok, so I guess the idea is this. wifi cards are getting pretty small these days. So I was wondering if it is possible to create a wifi card that attaches directly to the ext. port. But I mean something small kind of like the size of a AAA battery that won't be too noticable. Just wondering.

It would be very very slow; last I checked that's 2 UART ports there. The absolute maximum possible data transfer rate over them is probably under 10KB/sec. There are already SDIO WiFi adapters, wait for a driver.

ok makes sense. Thanks for letting me know.

USB host is also supported through the EXT, so don't be so sure it'd be slow.

Were you to rig up an adapter to say. some little USB Wifi adapter and write a driver for it, that'd be workable, yes. But I don't expect that'll be too soon.

Yes, but does the GP2X's SD slot support SDIO or is it just a standard SD slot? The SD slot must support it on the hardware end as well.

It seems it should. I did note SDIO support in the MMSP2 SoaC the GP2x uses as its primary component.

sdio wifi = no sd card usage when on the net

Sandisk and another company make combination storage/WiFi cards meant for PocketPC devices, I had a 256MB+WiFi model. It worked stupendously.

you could also use a usb hard drive while using sdio wifi.

so with the wifi (and i know this may be a little far fetched) would somekind of multiplayer server program (kinda like killera) be possible for the emulators. Basically multiplayer online emulators. It would be sweet if i could play contra hard corps with someone else online....

Don't forget that if you plugged it in via the usb it would have to use an external power source considering the 100 ma limit presently coming out of the EXT port .

I think that a powered BOB with wifi built in will be possible in the near future . But something just dedicated to Wifi would be stupid considering you would have to utalize the powered usb anyway you might as well ad a couple other connections ( considering it is just a wiring issue) .

I hope anyone considering using Wifi on their '2x considers the kind of shit battery life they're going to get...
