Return to Zork

scoriae · Post by **scoriae** » Thu Apr 24, 2008 2:04 am

Ok - I'm fully aware that the M4 and MADE engines are fetal, I was just messing around with them and getting my games prepped to be read by scummvm. The M4 games all seem to detect just fine (which at least confirms I have identifiable versions), but the MADE games I have weren't popping up. So I looked at the detection.cpp file to see what the short names were and saw that only Return to Zork had been defined so far. I tried running it via command line and it told me I had an unknown version. Specifically,
"rtzcd.red", "946997d8b0aa6cb4e848bad02a1fc3d2", 27658

So now I'm wondering if there were multiple versions of this game? I have like 5 copies of the cd game laying around and according to wikipedia there was a floppy version. Is that the only one currently detected? Or am I just jumping way too far ahead here and need to give it a while before I even bother....

Your rtzcd.red file is only 27,658 bytes? (I think that's what the message means.) The one on my CD is 276,177 bytes - almost ten times bigger, and the MADE engine recognizes that one.

thanks - I'll look into that

Ok, so I checked 2 standalone RTZ cd's and I also checked my RTZ version that i have in the zork anthology. In 2 of the versions my rtzcd.red file is 270kb (anthology and 1 standalone) and on the other it is 278kb. far from 278 megabytes.

The largest file I have is RTZCD.PRJ at 42 megs.

I also tried imstalling through dosbox to see if a larger rtzcd.red file would be created, but it was not.

The 279k rtzcd.red file is actually older (Sept 93) while the 270kb is from Sept 94.

Neither is recognized by scummvm.

Nobody said anything about 278 megabytes - eriktorbjorn mentioned 276,177 bytes - which is about ~278kbyte, pretty much the same as you seem to have.

Indeed. What confused me (still does, actually) was the message that suggested that the file was only 27,658 bytes, or ~27 KB.

I read that wrong, so yes, mine is in the approximate size range. The two questions now (for me) is why it detects it as being smaller than it really is, and secondly, why there are different sizes/versions of it.

Only one of my 3 rezcd.red files was 278kb, the others were both 270kb which is ~10kb smaller than what it expects. And my 278kb file is ~2kb larger than what it expects.

Searching online for a comprehensive list of versions hasn't yielded much in the way of results for me.

What language is the version of Return to Zork that you got? Only the English version has been added

They are all english.

I tried adding Return to Zork with the first release, that did not work on my mobile build. Bulding the latest from SVN now, it worked on the PC Svnbuild so should do the same on my phone I hope.

I don't think it detects it smaller than it really is, but rather you forgot to paste the last digit.

I have the same version and I get this:

Code: Select all

Your game version appears to be unknown. Please, report the following
data to the ScummVM team along with name of the game you tried to add
and its version/language/etc.&#58;
  "rtzcd.red", "946997d8b0aa6cb4e848bad02a1fc3d2", 276584

If I add the MD5 to detection.cpp the game seems to work. As far as it 'works' at the moment anyway.

scoriae · Post by **scoriae** » Thu Apr 24, 2008 8:50 pm

Ah - yes, it is possible I forgot the digit - I was retyping the message from a small cmd window, it may have been off the screen or on the next line or something.

Unfortunately I lack the knowledge and skills to add an MD5 and compile the source - it was a stretch just for me to download the source and firue out where to look for the game's shortname.

Hopefully my information I've provided will be helpful in identifying various versions of the rezcd.red file. I can submit the exact file sizes in a bug report if that is preffered.

And voila.. Return to Zork movie on my Nokia 6120 Classic with an 2 inch screen.

Impressive.

FYI - I found the RTZ 1.1 update executable and ran it on my files. It made both my floppy and cd versions recognizable.

I dug out my old RTZ CD and here's what I got:

"rtzcd.red", "946997d8b0aa6cb4e848bad02a1fc3d2", 355442

It's the german CD version 1.2:

readme.txt wrote: CD-ROM Return to Zork, Version 1.2, Datei READ.ME
4/18/95

This is the "original" CD version, i.e. no budget or cover-cd re-release, as far as I can remember (I threw away the box some years ago).

The game is detected correctly by ScummVM, but when I try to start it, it spits out an error about an unsupported version.

It would be nice to have this version supported. In the meantime, I'll try to hack it into the source code myself...
