SFA3 Dream Key help

[rouken]

Ok... Let's start from the beginning.

Street Fighter Alpha 3 is a amazing game. This version of the game for Dreamcast features an amazing mode called Saikyou Dojo, when you can use a custom character created in the World Tour Mode in the Saikyou Dojo, when you face powerful challengers. But this mode comes with just 3 challengers in the game, and the other 27 challengers the player must connect to the Internet and download the "DLC" to the VMU using the Dream Key comes in the game. But the Street Fighter Alpha 3 Homepage for Dreamcast is gone from a long time, and GameFAQs don't have the saves. But I got all the challengers, and I think it's a waste to have a Dream Key in the game if there's no use for it anymore.

So, I got the idea to create a custom SFA3 disc with all save files and use the DreamKey as bridge to download the files to the VMU. With this, everybody can use one disc for everything. And people don't need to use the DreamShell + a SD adapter, or a Dream Explorer / VMU Tool to do it. In other words, a complete Dreamcast version of Street Fighter Alpha 3 with all contents in the same disc.

The main HTML file was modified and it got a new occult link at the logo, and it leads to a new page with the files to download, as the image bellow:

Almost everything is ready, except for one thing: The Dream Key don't recognises the VMI file as a VMS address, and it can't load the file to send the save to the VMU.

I found this (unofficial) VMU FAQ, and it says the server needs to recognises the file as a Dreamcast file, not the browser, and it must be done using specifics commands in the server. But I'm putting the file in the disc, not in a server.

With this, I come with the question: What I need to do for the Dream Key in the Street Fighter Alpha 3 disc recognises the files correctly?

For now, I already thank anyone can help me.

For some help, I must to say the SFA3 don't run in the nullDC, but if we exchange the names of the 1ST_READ.BIN and 2_DP.BIN to each other, the SFA3's Dream Key can run without start the game. Chankast run the game, but the option to access the browser got disabled in it...
