I've recently lost an usb to gba cable for my EZF Advance 256M cart and after searching for days consider, it gone for good. I looked up the EZF-A site and it appears to be down, so I plan on cutting up some spare usb/link cables and making my own. I was wondering if any one knew or could be bothered, to find out which pin on the usb end connects to which end on the gba side with their existing cable. This would save alot of work for me when I make a replacement cable.
Thanks alot, K.

After over ~12 days of searching and 5 min after my post, my cable appeared out of no where. I guess it was just waiting for me to post this ;P. I will, however, post the diagram on my web page in case some one else suffers the same fate.
Thanks anyways, K.

Hi,
I am also interested in that diagram. Could you notify us when you have done it?
Thanks
VInce

I used my EZFA cable to death when I was testing BA Advance for GBAX, so I smashed the thing open to see if it contained a simple USB -> GBA pin connection. Unfortunately, the normal EZFA cable is loaded with a couple of IC's down the GBA end... I wouldn't know the first thing about duplicating the functionality. :(

The ICs are normal. For the F2A/F2A Ultra, it's an AN2131/EZ-USB chip. I am wondering what chip the EZFA uses.

It is hard (if not impossible) to use the USB cable just by itself. You need to use IC's to support your design.
Im really sorry im too late, cause if i posted this earlier you would'nt have smashed your cable open. But since you've already done that, why dont you tell some of the people here the IC's serial number.

I'm sure there's ways and means and special carts that would accept a straight patching of pins... maybe with some kind of voltage check, though. (maybe some kind of Xboo derivative?)
I couldn't tell you about the cable's specs... it broke months ago, I kinda threw it away. :(

Despite the fact that the "S" in USB stand for serial, you won't be able to connect a GBA port stright through to a USB port. Can't be done without support circuitry.
(This is not just voltage level shifting).

Does anyone continue the search for the hardware inside the EZFA linker? For the moment I am starting to play with the D2XX provided by the FTDI website and compare the output with the captured output of the EZFA client 1.03. But it could help (not sure) if the hardware after the USB chip is known.
Kind regards,
Jan

You're thinking of EFA, right?

I'm thinking hypothetically... I've never used the EFA before, so I couldn't say. (I've only used EZFA.)
There's gotta be at least one cart somewhere that uses a standard USB A - A or A - B connector. (Or, god forbid, one of those crazy digital camera ones which I always get mixed up between) Surely... you could just put the magic support circuitry gadget that, say, resides in the thick end of the cable (like ezfa) onto the cart itself, if there were space. And then you could just use a USB extension lead into the flash cart.

That's EFA. PHWiki has more info. But then because the cart connects directly to the PC, you can't use the linker to make a fair-use dump of an authentic Game Pak.
