Description

Here is an update on how the games behave on my Dreamcast – thanx to the resumed builds from Chris Paras. The build I have tested this time is 0.5.0pre-CVS which Chris Paras made 7/7-03. All games are English version. Here it goes:

Maniac Mansion (enhanced): WORKS! Playable.

Day Of The Tentacle: There is a stutter in the game/sound – I think it is a problem that has its roots in the process of loading from the CD, maybe some kind of buffer is needed. Playable.

Zak McKracken and the Alien Mindbenders: WORKS! Playable.

Loom (256 color CD version): WORKS! Playable.

Indiana Jones and the Last Crusade: Game seems to work fine – just one thing that is wrong - you can’t fight in the boxing ring, there is no button on the controller that makes you punch. Playable.

Indiana Jones 4 and the Fate of Atlantis: There is a stutter in the game/sound – I think it is a problem that has its roots in the process of loading from the CD, maybe some kind of buffer is needed. Playable.

The Secret of Monkey Island (VGA CD): WORKS! I think the music/Soundtrack is OK now. Playable

Monkey Island 2: LeChuck's revenge: There is a stutter in the game/sound – but not much. Playable.

Curse of Monkey Island: There is a severe stutter in the game/sound – I think it is a problem that has its roots in the process of loading from the CD, maybe some kind of buffer is needed. The intro is corrupted, and you have to skip the intro to play the game otherwise it will crash. The game is NOTplayable at all.

The Dig: There is a stutter in the game/sound – I think it is a problem that has its roots in the process of loading from the CD, maybe some kind of buffer is needed. Almost playable.

Sam & Max: There is a stutter in the game/sound – but not much. Playable.

Full Throttle: There is a stutter in the game/sound – I think it is a problem that has its roots in the process of loading from the CD, maybe some kind of buffer is needed. Can’t skip intro. Sound is bad, and sometimes the sound go off and there is a high static noise.

Beneath a Steel Sky: There is sound but no picture while the intro is running. Crashes after intro.

Simon The Sorcerer 1+2: Doesn’t show up in the menu at all.

Thanks for the detailed report!

We've reverted to an older faster version of the sound code, so the stutter should hopefully be gone for most games - except Dig/ComI/FT which use their own sound engine.

Marcus, can you check if the stutter is eliminated in the current CVS? It's also be nice to check why the DC game detector doesn't find Simon, and check Sky again if you have it (it should be endian safe now).

ComI probably shouldn't crash either, but maybe the DC is just running out of resources for that one.

Oh yeah, Torben... why do you mark "The Dig" as 'almost playable' - is the stutter that severe?

comment:4 by SF/tskywalker, 17 years ago

Hi James

I gave The Dig the almost playable label, because you can play the game, but the stutter is severe enough to have an impact on the gameplay. Another way to put it, is that The Dig lies between the games that have a stutter but are playable, and Curse of Monkey Island, where the stutter is so severe that the game slows down to being a slideshow. Maybe stutter is not the right word (my bad English I am Danish), its like the games, that have a stutter, hangs when something changes in the game: the character says something, the location changes, you click on something and so on. Its like the game cant read fast enough from the CD as far as I can see the stutter is concurrent with reading from the CD. Keep up the GREAT work you all I am looking forward to a new release, I am sitting with tears in my eyes when I am playing those great games again on my big Screen TV (witch by the way was some of the first games I played on my computer). Anything else about how the games behave on the Dreamcast just ask.

Ender:

Yes, the ComI intro aborts (it doesn't crash, it just exits to the boot menu) because it allocates to much memory and runs out of the stuff.

I do own a copy of Sky (Amiga floppy version), but I don't have it here, it's at my parents' place. So it will have to wait.

Torben:

The Dreamcast can read plenty fast from CD, _however_ if it is forced to read from two places at once (for example both streaming sound and loading resources) it won't be able to _seek_ fast enough to maintain read speed for both. Seek times are always high on CD, it's not a Dreamcast-specific problem.

Hi

Here is a quick update on how the games behave on the Dreamcast with the build made on 12/7-03. I have only included the games where there is something new to add. ScummVM 0.5.0 pre-cvs 12/7-03 All games are English. Here it goes:

Indiana Jones 4 and the Fate of Atlantis: There is a stutter in the game/sound. The game hangs in the cutscene where the bead is inserted in the necklace, and there is an error message: failed to load game state from file: ATLANTIS.C99 . Playable.

The Dig: There is a stutter in the game/sound. Crashes in the cutscene where the explosives are set of on Attila. Almost playable.

Full Throttle: There is a stutter in the game/sound. You can skip intro now, but the intro crashes after a while anyway, if you dont skip the intro it still crashes. Sounds is bad, and sometimes the sound go off and there is a high static noise.

By the way Marcus I see what you mean is there a way to resolve that problem??

Indiana Jones 4 and the Fate of Atlantis: There is a stutter in the game/sound but not much. GREAT - now the game doesnt hang in the cutscene where the bead is inserted in the necklace. Playable.

The Dig: There is a stutter in the game/sound. Crashes in intro you have to skip intro to play the game. Crashes in the cutscene where the explosives are set of on Attila. Almost playable.

Closing this for now. The Dreamcast port has a LOT of bugs in the non-SCUMM engines, not least of which is that the non-SCUMM engines do not use the SaveFileManager so DC users can't save.

Unfortunatly, Marcus appears to have very little time to maintain this port, so I don't see any reason to keep this open.
