Reported by: SF/tskywalker Owned by: zeldin
Priority: normal Component: Port: Dreamcast
Keywords: Cc:

Description

There is a stutter in the game/sound of varying degree
in some of the games, when played with the Dreamcast
port.
All games are English versions.

There is a stutter in the game/sound – but not much:
Indiana Jones 4 and the Fate of Atlantis
Monkey Island 2: LeChuck's revenge
Sam & Max

There is a fair amount of stutter in the game/sound –
but the game is playable though:
Day Of The Tentacle
Full Throttle
Beneath a Steel Sky

There is a severe stutter in the game/sound – the
stutter is so severe that it has a big impact on the
gameplay, the game is almost playable though:
The Dig

There is a so severe stutter in the game/sound that the
game slows down to a slideshow – the game is not
playable at all:
Curse of Monkey Island

To process your bug report appropriately, we need you to
provide the following additional information:

* ScummVM version (scummvm -v)
* Bug details, including instructions on reproducing it
* Language of game (English, German, etc)
* Version of game (Talkie, Floppy...)
* Platform and Compiler (Win32, Linux, MacOS, etc)
* Attach a save game if possible
* If this bug only occurred recently, please note the
last version without the bug, and the first version
including the bug. That way we can fix it quicker by
looking at the changes made.

This should only take you a little time but will make it much
easier for us to
process your bug report in a way that satisfies both you and
us.

Thank you for your support!

Hi Marcus

We were discussing in one of the forums, if there is mp3
support for the Dreamcast port, or will be?
And consequently, if it were possible with some kind of
packaging, of some sort of sound and/or music and/or
speech, if that maybe would solve the problem with the
stutter in some games?
Any thoughts??

MP3 support is there if you have libmad for the Dreamcast
and enable the support when compiling. It is not included
by default or in the binary distributions.

Since the "stutter" is caused by the main CPU being too busy
with other things to fill the audio pipe, causing it to
underrun; adding decompression, which just adds to the
general busyness of the main CPU, would only make things worse.

Hi Marcus

As usual I see your point.
Thanx!

I'm closing this for now.

I need to talk to Marcus regarding DC support for 0.6.0 -
the port needs some work, may need to get somebody else
working on some of these problems.
