Future Wars problem

The cd version of FW doens't work under ScummVM.
It is recognized, but all I get is a black screen, and ScummVM hangs.

According to the wiki page the CD version was only released in the US, and as far as I know, no team member has it. Does ScummVM report any unknown md5? Does it report anything on the debug console? What version of ScummVM are you using?

Looks like that version is using some new opcodes that aren't used in any of the Future Wars or Operation Stealth versions I've seen. My guess is that they handle the CD audio related stuff but that's only a guess.

Please, if you could run the game using the following command line (You may have to go to the directory where scummvm is installed first to be able to run this successfully and I don't know where that is with Mac OS X so hopefully you'll manage

):

scummvm --debuglevel=5 --debugflags=Script,Part fw-1 > fw-cd-output.txt

What that should do is run the game with more debug info being printed and redirect the output to fw-cd-output.txt file. The file may get a bit big so if you have any compression program that supports zip or bzip2 or gzip or whatever you could compress the text file with that and send it to me at buddha AT scummvm DOT org and I could take a look at what the file contains. Thanks.

Hmm, could you give a listing of all the files in your Future Wars CD?

Also md5sums would be nice (Of the first 5000 bytes of each file and of the whole files). You can get a program that calculates md5sums from http://md5deep.sourceforge.net/ (It should work under Mac OS X too) and get the output by running it like this:

To get the md5sums of each file's first 5000 bytes:
md5deep -p 5000 -r * | grep "offset 0-5000"

To get the md5sums of the whole files:
md5deep -r *

You can dump the outputs straight here as they shouldn't be extremely long. Thanks.

Comparing to my floppy disk version of Future Wars that I bought back in the day there are a few notable differences:

AUTO00.PRC, PART01 and FWARS.EXE files are different from my version.

Your PART01 file is about ~5kB bigger than the one I've got.
So there are some new resources included with your version.

Your AUTO00.PRC file is 253 bytes, mine is 128 bytes. So there's some different code in there.

Your FWARS.EXE is 111kB, mine is 44kB (And named DELPHINE.EXE actually, but that's not important). So there seems to be very much a difference there.

The MANUAL.EXE and MANUAL.GRS are new files but they aren't probably needed to execute the game (They're probably just for reading the manual).

SONY.LBM is also a new file but it's probably just SONY's logo.

DISP.EXE is also new and perhaps it's for showing the SONY's logo (SONY.LBM), dunno.

Buddha · Post by **Buddha** » Fri Aug 08, 2008 4:12 pm

The AUTO00.PRC seems to be the culprit here or the way it's being parsed currently (There were no new opcodes used in the executable, I checked. PART01 unpacks alright too so it's not corrupted). Somehow parsing the AUTO00.PRC results in the engine thinking that there are some nice new opcodes to be ran and a little later it just crashes.

noize · Post by **noize** » Fri Aug 08, 2008 5:02 pm

Great.

Disp.exe indeed displays logo.
Fwars calls disp.exe on start.

This version does not use copy protection. (Which I assume means that protection screen can be removed from ScummVM)

Buddha · Post by **Buddha** » Fri Aug 08, 2008 5:06 pm

Can you play the game without ScummVM i.e. using some emulator like DOSBox or Bochs + FreeDOS or just some plain old DOS machine if you have one lying around somewhere? I'd like to know because if the game *does* work then there has to be a routine in FWARS.EXE that handles the AUTO00.PRC differently than ScummVM currently does.

My current guess is that your AUTO00.PRC is corrupted but not 100% sure yet. It'd help if you could run it otherwise than using ScummVM.

noize · Post by **noize** » Fri Aug 08, 2008 5:16 pm

I just downloaded Dosbox.

Game works. Same graphics as floppy version. No copy protection. With cda support.

Buddha · Post by **Buddha** » Fri Aug 08, 2008 5:23 pm

Interesting. Then the FWARS.EXE you have must somehow handle the AUTO00.PRC differently than ScummVM does... as your AUTO00.PRC looks like corrupted data to ScummVM currently.

Buddha · Post by **Buddha** » Fri Aug 08, 2008 5:39 pm

Getting somewhere here... FWARS.EXE definitely does some bitfiddling with at least the AUTO00.PRC

. So the file's *not* corrupted.

Good stuff.
