Great work!!
is it possible to solder a SD adapter directly onto the dreamcast motherboard? without buying a VSCable or coders cable, thos are really hard to get

Wow thats pretty great.But one thing I dont understand,didnt most people say the serial port wasnt fast enough this kinda stuff?Too bad they still arent selling it, running katana tech demo would be cool.

"Fast enough" depends on how the game program reads files and how patient the user is. The serial port's top speed is much slower than the GD-ROM drive's top speed for sure (I think somewhere in the range of 10%). However, reads of small files can be faster because an SD card's seek time is practically zero compared to the GD-ROM drive.

Not 10%, about 50% of the average speed of reading GD-ROM.
SD card connected to the DC, is equivalent to reading the GD-ROM at a speed of 4x (~500-600 kbytes/sec), plus the lack of pathfinding.

What serial clock rate are you using? I thought it topped out at ~2MHz.

If use External Clock Input = 5 MHz and Pf = 30 MHz in Synchronous Mode, you can achieve speeds of 5000000 bits/s.

Are you using an external clock? That's not in the jj1odm schematic, and I haven't seen mention of it anywhere else, so I thought everyone was using an internal clock. I've also seen several mentions of transmission being unreliable at higher speeds, although those may be talking about a longer cable.

I use "Dreamcast Serial <=> SPI interface by jj1odm"

The module only supports ISO 9660 images, which can create both:

mkisofs -V DC_APP -G IP.BIN -joliet -rock -l -o image.iso ./dir_with_files

In IP.BIN where there is a parameter GD-ROM/CD-ROM should be set to GD-ROM for the KATANA and CD-ROM for Homebrew.
LBA in KATANA BOOT.BIN must be patched by 0 (zero).

For those who do not know how to create ISO images, I made this package, it is the way the identity updated: iso_make.7z

If they could make a browser for it, that could read CSS and other things, it would be just great. :grin:
