Connecting IDE disks & ISA (network) card to Dreamcast

[cybdyn]

my board has option "IDE <-> fpga <-> gd-rom conn", i can test your code, or help in developing. so dont count me out)))

i more rather need inforation about "SPI" command set and any details on this low level. also i need few good advices on file system level of SD card. (see P.M)

also - if i get any good result maybe you will be interesting in my board? ))
