ISO9660 support

ISO9660 support

[Gary Thomas]

Gents,

A long time ago (Dec 2001), Jesper was working on a contributed
port for the Sega (IIRC) that included ISO9660 support in RedBoot.
That never made it into the official tree, for legal reasons I
believe.  Does anyone know what happened there?  Is there some 
way we can follow up on this and get the support put in?

Just because it would be nice and also the remnants that are
left make the code messy for little reason.

Thanks.

FYI I don't have the original contrib any more so I hope someone else 
does. I believe part of the issue was that it was added pretty much as a 
crude hack, rather than it being legal issues (the rest of the dreamcast 
port was assigned obviously). And there was no way to test it too as you 
needed some special equipment IIRC. But Jesper will know so I'll shut up :-).

I might still have the contrib somewhere, but a better place to look
is http://www.m17n.org/dodes/ecos/. That takes you to a CVS repository
containing
http://cvs.m17n.org/cgi-bin/viewcvs/ecos/ecos/packages/fs/iso/?cvsroot=superh

You should also be aware that a dreamcast does not have an ordinary CD
drive. Instead it has a GD drive with ~1GB capacity. From another
website:

"A GD-ROM disk actually consits of two data regions, separated by a
data-less separator ring. The inner region contains a normal Yellow
Book CD-ROM track, and a Red Book CD-DA track. This region can be read
in any CD drive. The outer region (outside the separator ring) is the
high-density area which contains the actual game data (both files and
CD-DA audio)."

I don't know if that affected the ISO support, they may have supported
the inner region only.

Thanks for the pointer.  I've downloaded the code and I'll give it a
glance to see if somehow we can use it.  On first look it seems to be
a little too Dreamcast specific and there are no copyrights in the code,
so it may take a little effort to bring it in.

You should definitely confirm the copyright status, including as Jesper 
suggested, whether any of the code came from elsewhere, Linux kernel or 
otherwise.

I think the problem was that he had lifted the code from the Linux
kernel. But I'm not 100% sure.

Sorry, I don't remember anything specific about it. And I don't think I
have the code...

As I thought - I can't find the code either so I guess we're at step 1.

Nice to hear from you, Jesper.  How's life treating the married man?

Really well, thanks!

Time flies, and I'm enjoying both married life and my new job :)

The company is trying to sell our electronic patient journal software to
some of the solution provider corporations in UK, so the UK guys may
(should they end up in hospital) risk being taken care of with the help
of some of my Java hacks (pity the poor bastards ;)

Cheers,
Jesper
