Executing code via HIT-0400 BBA

Post#1 » Fri Nov 24, 2017 9:54 am

I'm a Linux user. I manually installed KOS on Linux Mint and can compile the sample applications. I can't find any info on uploading code to the DC via BBA. All websites with this info are now probably dead. Can anyone point me to any archive.org sites I can find this info on?

I know how to make a *.cdi and burn it. I own an SD card serial adapter also. I don't want to wear out the hardware. I'm looking to set up my computer so I can click and watch the code execute on the device like an Android/iOS developer would with a phone.

I finally found the info needed here:

One needs to make a crossover network cable, burn the provided *.cdi that listens for stuff to execute. The software for sending from the PC side is very old though, I'm still trying to compile it for my kernel as the binary won't run.

I can now compile and push the binary to the Dreamcast like an Android/iOS developer. There's a lot of reading between the lines but it's worth it.

you need dcload-ip then ARP the dreamcast MAC address to an IP, then using DC-Load GUI 3.0 you can select the binary to execute

arp -s <dc mac addr> <ip addr to assign the dc>
might have to put the IP first, i forget

Can you put your notes / code on GitHub afterwards?

Not that i may ever have a need for it, but just for the sake of preservation?

Thanks :)

DCDev - Connect to Your DC

Back Home
Get a Dreamcast
Get a DC Coders Cable or a Broadband Adapter
Use the cable or the adapter to connect the Dreamcast to your PC
If you have a Coders Cable, download the DCLoad Serial Kit; if you have a Broadband Adapter, download DCLoad IP Kit
For the sake of this tutorial I'm going to use a broadband adapter, so burn the dc-load ip image you downloaded to a CD via DiscJuggler.
Insert the CD into your Dreamcast and switch your Dreamcast on
Once running you should see some text displayed. The third line on the screen is the DC's mac address. We'll be using this later.
I have an ethernet and wifi card in my computer so I'm going to use ARP and map the dreamcast to a local IP on my ethernet card. Set the IP address on your computer's card to
Then run in admin mode: arp -s yourdcmacaddress This maps the DC to IP address on the interface.
You now should be able to ping the DC by running: ping
