Is there any way that the Dreamcast can have Flash Drive or SD card memory ?

There's a japanese guy that managed to put a sd card on the dc, that uses the serial port, so you can load bins from the sd card and dump retails to it. I know nothing more about it beside this diagram:

Here's the japanese link(browse down until you see a sd card):http://f17.aaa.livedoor.jp/~takotako/dc ... php#sdcard

Here's the "translated via google" page:http://translate.google.com/tra [...] &prev=%2Flanguage_tools

Thank you

That shit is tight. Someone should mass produce it or something.

Yeah, I've thought about doing something similar for Saturn. The full SD protocol is somewhat involved, but the SPI protocol used with that adapter is extremely simple. The downside is that you're limited to somewhere in the range of 20-25Mbps of raw transfer rate, but that's more than enough for most applications (and certainly more than DC's serial port can handle anyway). There are also reportedly some crappy SD cards that don't support SPI mode or don't support it properly, but as far as I know those are pretty rare.
