| Is it taboo to ask questions about Utopia's CD Loader in
rec.games.video.sega or alt.games.video.sega-dreamcast?

As long as you're not using it to boot pirated games, naw, not at all.

Wouldn't dream of it.
I'm having problems getting it to work, though. My Dreamcast will fire
up self-booting discs, games as well as CD Loader, but I can't seem to
get CD Loader to recognized and execute a "vanilla" version of the game.
I don't know how to tell if the disc images I'm working with are crap,
or not. Can I just burn the second track of a selfbooting game to a
blank disc?
This is all pursuant to getting a late model Dreamcast to be able to run
backups, but I would be happy to solve this intermediate problem. Any
assistance or direction you can offer will be appreciated.

By late model, are you meaning that the DC was made on October 2001 or
later? I recall that burns (like the Utopia disc) won't work in those.

That is indeed what I mean by late model. There are *two* Dreamcasts in
my remarks, though, and I'm having problems with an "early model"
Dreamcast. It will boot Utopia without any problem, but it would not
run a backup from there.
As it turns out, it looks like the problem was with my burning software.
I was using BootDreams to burn CDIs, but they were not working.
At this point I have some other questions about creating boot discs
specifically for late model Dreamcasts, but I'll defer those until I
accomplish a bit more research.
Thanks for your responses, Relic and BelPowerslave.

While there are some DCs with a bios that won't allow boot discs (or
real MIL-CDs, or anything that is meant to take advantage of the MIL-CD
loading thing), I have yet to see any reliable reports that any of them
showed up in US DCs. They definitely showed up in the pink Sakura Taisen
DCs in Japan, but every report in the US has seemed to come from people
who didn't know what they were doing or people whose lenses weren't
adjusted properly/were dirty.
I wonder if the relevant alteration is on the DC's motherboard or if
it's in the drive assembly setup somewhere. If it's in the drive, I
could easily see units that were refurbed late in the game in the US
having this issue, but then the date on the hardware would be meaningless.

Is it possible for the lens to be out of adjustment for MIL-CD but not
GD-ROMs? I have two Dreamcasts that perform differently:
+---------------+------------+------------+
| Manufacturing | Reads | Reads |
| Date | MIL-CD | GD-ROM |
+---------------+------------+------------+
| April 2000 | yes | yes |
+---------------+------------+------------+
| December 2000 | no | yes |
+---------------+------------+------------+
I've followed some instructions to generate a CD Loader disc that uses
Data/Data tracks instead of Audio/Data tracks, but had some problems
that may have been the result of a screwy DiskJuggler install. I
basically bought the April Dreamcast as a tool to assist in making the
December unit boot the CD Loader.
Any related advice you can offer would be appreciated.
Oh, here's the tutorial I had previously followed, and will by
attempting again:

Do you have any pressed MIL-CDs?
The general sentiment seemed to be that DCs would often not read CD-Rs,
but that a cleaned or adjusted lens would often fix that problem. So the
failure wouldn't have anything to do with the MIL CD format as such,
just with the media it's on.

Not that I know of.

The Dreamcast in question has no problem reading Audio CDs burnt onto a
CD-R, but it's worth following up you implied diagnostic. What would be
a cheap and ready supply of pressed MIL-CDs?
I know that Wikipedia's bona fides have taken a hit of late, but the
article there on the Dreamcast also says:
| Dreamcast used a proprietary format called GD-ROM
| (Gigabyte Disc Read Only Memory) or "GigaDisc" for
| storing games in order to discourage software pirates,
| although it had similar overall technology to the
| CD-ROM. However, the first run of discs had a high
| rate of defects; and eventually pirates managed to
| copy the games anyway (in some cases distributing them
| before the release of the legitimate versions). The
| primary reason this was possible was the existence of
| regular-CD booting code in the Dreamcast BIOS to
| enable multimedia functions (called Mil-CD) for music
| CD releases on the Japanese market; this was
| eventually discovered and exploited by pirates. Mil-CD
| support was removed from the final Dreamcast revisions
| toward the end of the console's life, but rampant
| piracy is often cited as one of the major reasons for
| the failure of the Dreamcast.
