Re: DC dev: requirements?

  Hello,

I'm guessing you've seen Marcus Comstedt's Dreamast software site. I 
built a few bootable Dreamcast CDs several years ago...Then got tired of 
making CDs for every update and burned an IP Upload Slave CD.

If you want to continue down the path of burning CDs with kernels and 
such, you should probably check out Marcus' site:

http://mc.pp.se/dc/sw.html

You'll probably want to pay particular attention to the IP creator and 
1ST_READ.BIN scrambler.

Hopefully that helps.

I haven't touched my Dreamcast in years except to play actual _games_ on 
it. I should maybe see about building the latest version of NetBSD for it...

Cheers,

Josh

Security is mostly a superstition. It does not exist in nature, nor
do the children of men as a whole experience it. Avoiding danger
is no safer in the long run than outright exposure. Life is either
a daring adventure, or nothing.
