Description
This patch add the support to the mac version of Broken Sword 1. It adds the mac BS1 game detection code and byte swap for some of the resources. Note that the mac cluster files mainly use the big endian bytes order, but some of the resources are stored in little endian (e.g. mouse cursor or data for router). All the byte order conversions are now done by functions in the ResMan class, except when dealing with the static resources (from staticres.cpp) that are always in little endian format. I have tested both the mac and PC version with french voice and french or english subtitle on a little endian computer. Hopefully I did not break anything, but I am not completly sure that BS1 mac will work with ScummVM on a big endian computer.
Support for the mac music file (in AIFF format) is not implemented.

The patch looks ok to me. I don't have Mac version neither full game nor demo to test, but at least PC versions aren't broken.

Besides, can you put the demo somewhere online at least for a short period of time? Or come to IRC and DCC to some of the devs? I couldn't find it anywhere, at least easily.

The demo probably does not exist. When working on the game detection code I though I remember playing the demo a long time ago before buying the game. And I also tough it would be easier to remove the mac demo detection code than to add it latter. Since then I had a look in my old CDs collection and did not find it. Nor did I find any mention to it on the internet.

We could try to ask the Revolution guys, maybe they would at least know whether such a demo ever existed?

I briefly tried this patch on my (big endian) PowerBook under OS X, and BS1 (PC version) seemed to work fine there, too. Well I didn't do much more than walking around a bit in the first two scenes... Anything specific I should have tried to trigger potential problems?

The two points of the modified code on which I had some doubts concern the mouse cursor creation and the route finder. The first one would probably cause the game to crash right at the beginning and the second one would cause some problem when walking. So you would probably have noticed them if there were important bugs remaining in this code.
On my side I have now played two third of the game with the mac version (and music re-encoded in ogg) on an intel mac and encountered only small issues. Most of them where present in the original game. The only issues that I do not remember from the original game concern background colors in some places: when George enter or leaves Nico's flat, the color in the door opening is bright red (see attached file). I do not remember what the color was in the original game, but I do not expect it to be this one. I had a similar problem in Syria as well (at the bull's head location, with the sky being green).
I also had a llok at the music files, and it seems to be AIFC (a variant of AIFF ?)

AIFC is indeed a compressed AIFF variant. There are plenty of docs for that on the internet, just google.

Max, if you have no objections, I would commit this patch to SVN.
criezy, may you send me couple of those files in AIFC format, so I could add support for them in ScummVM?
comment:10 by , 18 years ago
I commented out Mac Demo detection until at least someone will confirm that it exists and works with current code. Otherwise the patch was committed as is, thank you for it. I'm still waiting for AIFC files.

Sorry for the delay, I am just comming back from an oversea seminnar. I can confirm that the mac version is completable and I didn't have any crashes.
Sev, for the AIFC files do you want me to send them to your adress at users.sourceforge.net ? I am not sure if I can attach the files to this thread as there is probably some copyright on them.
