This is what you've been looking for, the last releases of the games!
These are images I never shared before. I use it to help me calibrate
Dreamcast reader.
Games distributed on password-protected packs were repacked without it.
It's common for Dreamcast reader to get bad after some time. However,
the cases I saw could be fixed by calibrating the reader. There is a
screw on the lens block that you can adjust, and depending on what you
do there you'll make it read better or worse. I'm lacking photos at the
moment, so you'll have to look somewhere else for the location of this
screw, and for instructions of how to change them.
Please notice that DCRES has evolved a lot over time. It started by
simply making games selfboot, downsampling some things and using GD file
order, and ended a much bigger thing. Highly cool custom optimization
techniques have been developed, protections have been broken, custom
formats of files opened from scratch. Games never released properly had
been make it available for everyone to play on their Dreamcasts with
high quality, others that had good releases were made better. Not bad
for a one man project right?
What I noticed, is that bad readers have difficulties recognizing multi
session discs (selfboot discs). What also noticed is that it also
depends on where the second session start. Some readers won't work fine
for most releases (where second session starts near the beggining of the
disc), others will have difficulties with discs where session starts
close to the end of the disc (too many CDDA, or big games generated with
bin2boot). If that's your case, calibrating your lens should fix it (I
take no responsability though xD).
However, as I mentioned, things were evolving over time, so it's
expected to find not so good releases among the list, mostly the older
ones. For example, giving a quick look I can see some releases like Dead
Or Alive 2, Half-Life and Power Stone 2 that potentially could have been
made much better. I see "Genesis Collection" and regret of having
released an emulator pack under DCRES title. My wish was to review all
of them, but unfortunately that's not going to happen.
These discs can help you calibrating your reader. They're Dreamcast
layout discs with extreme cases: second session starting in the
beggining and in the very end of the disc. If can know if they were
recognized correctly by the noise Reader does. If you keep changing the
reader's screw, you'll notice that there's a point where it recognizes
great the first disc, but won't read the second disc. There's also a
point where the opposite occurs. You'll need to find a point where both
discs are recognized fast, that should be the ideal adjustment.
Anyway, looking back now, I'm very proud of my work. I'm very proud of
having been part of the scene (even if so many years later!) of one of
the greatest consoles of all time.
Since these discs you'll be used as reference, I recommend recording
them on a nice CD-R brand in a moment close to the calibration. I mean,
don't try to use the damaged ones your recorded one year ago on the
cheapest CD-R you could find.
Now stop reading and go get some CD-Rs :)
I calibrated my reader twice on my 2000 console during its lifetime,
using these discs on the second time. My Dreamcast is still awesome. I
played for 3/4 years intensively, and used it for all my releases, so
you can have an idea of how long these things can last if you
re-calibrate it.
