I've installed the sources of scummvm and I'm running it in step-by-step debug because I had this crazy idea that I'd love to dump all graphics of Cruise for a Corpse into some sprite sheets.
There are several reasons :
1) I think the graphics are gorgeous (in an Amiga 64-colors way) and I think it's a pity that they're not used as golden-age pixel art tribute as often and as easily as Lucasarts graphics.
2) I realized that this game could be much much more fun :
- if there were some proper music and sound effects (the current music is painful because chiptune doesn't fit 1930's French opera/jazzy music well)
- if the interface was slightly pimped up (less pixel hunt and more hinting)
The fact that the story isn't really branched (no big choices to make) makes it easy to revert-engineer.
I'd love to make it available as a template for AGS and then see what happens.
EDIT: I was daydreaming and I'm wondering who currently owns the rights to this? It was Delphine software --> Virgin --> ??

As far as I know, the majority of things that moved in-game were vectors, so I don't think there will be equivalent bitmaps to dump.

32 colours, without HAM.

I had the Amiga version, and remember the music being okay (and very effective for the intro sequence), but playing the game was pretty much silent.

...I never finished it, and always seemed to get stuck at the same point. You could 'talk' to the wooden mermaid to get a code, which I think would give you a hint from the copy protection wheel. It is on the bucket list to try it again one day...

Well they're
stored as vectors -- but on-screen they're ultimately rendered as pixels. So I want to save the whole thing as sets of sprites, in good old PNG files.

Yes, sorry. I never had an Amiga but I can spot when there ar emore than 16 colors but less than 256.

The intro music is cool. But then, later in the game, when you visit some rooms there are some extremely invasive chiptune melodies. They make you want to flee the room immediately.

The wooden mermaid thing was just an easter egg (if it ever existed). The terrible thing with that game is the complete absence of hinting which forced you to patrol the entire ship again and again in the hope of spotting a new object having appeared somewhere.
Apart from this gameplay aspect, the story itself was pretty cool (whodunit)

The Amiga version may have had a sample-based intro tune (https://www.youtube.com/watch?v=sTIKcYHRCWA), but the Atari ST version, which I owned, was a chiptune (https://www.youtube.com/watch?v=RcYUvavoQQA). I actually prefer the ST version, though. :)

I would hazard a guess at Ubisoft.
Yup, I too never finished this game. Didn't it have dead ends??
I loved the style and the idea of it, too.
I also thought it had dead ends, although perhaps this was just to cover up my own failings in playing it. I always seemed to get stuck at the same point.
So far I've succeeded to dump backgrounds and "normal" sprites (not polygonal sprites), and I'm on the verge of having the palette.
I've made a reader using AGS because I couldn't be arsed to program it with something too heavy with C++ in it ;)
My issue is that I dump things as they get loaded, so it means I can't dump the whole game and I'm dumping many things several times.
OK so here is what I did :

if ((ps.x != pe.x) && (ps.y != pe.y))
// At least part of sprite is on-screen
gfxModuleData_addDirtyRect(Common::Rect(ps.x, ps.y, pe.x, pe.y));
cellStruct* plWork = currentObjPtr;
int workBufferSize = height * (width / 8);
unsigned char* workBuf = (unsigned char*)MemAlloc(workBufferSize);
memcpy(workBuf, dataBuf, workBufferSize);
int numPasses = 0;

This generates files "export0.dmp, export1.dmp, export2.dmp, ..." for sprites and files "export100000.dmp, export100001.dmp, export100002.dmp, ... for backgrounds.
>> Download viewer << (https://www.dropbox.com/s/2pbfk7iv0uss3hj/CruiseDumpReader.zip?dl=0)It's made with AGS :D
How to use :
- Type in any number in the textbox (e.g. "6") then press return..
- after the sprite is displayed, press the left and right arrows to open the next or previous sprite. Pro-tip : If you started from sprite 0, then you should click "right" several times before you see anything interesting.
- Type 100000 or above to see backgrounds.

Nope. But it's the raw background. Then there's animation on top for each of them. The missing parts are the animated parts.
interesting to see how many times they use the same door assets and some other things. Can't blame them, I do the same, saves time.

That's all 1723 sprites
Unfortunately I screwed up the palette so i'll have to do it again, but this is a good start.
In retrospect, I realise that it's really heartbreaking how they didn't use their vector graphics engine to rotoscope the main character better than that. They had everything they needed for that, and yet they inserted this ugly polygonal guy into their gorgeous pixel art. Pity! the game could have looked like a fullscreen Prince of Persia. If they had followed this example (https://www.youtube.com/watch?v=c5kuYfTCGLg), the game would have looked like a proto FMV ...as early as 1991!
