So my initial problem is going to be getting it to run in Windows XP. I have a copy of Windows 7 on my desktop, but my trusty laptop still runs WinXP (it has a Vista licence on the back, but lets not go there ... ). Looks as though it's fully supported by DOSBox, which is helpful; an abortive attempt to run the installer using cmd.exe got me errors due to having too many partitions, and my CD drive not being D:. For convenience, I've ripped the CDs to .isos, since I've no interest in carrying them around.
It's kind of funny going back to 1993-era BBSes (mirrors, obviously) looking for patches, seeing FILE_ID.DIZ and the like. There are a few guides to getting this game to work in WinXP, but I wanted to chip in my own experience.
It looks as though the game was patched a few times, and there are three initial "graphics" patches, and other "version" patches. First off, the graphics patches, distributed separately as: T7GF3A.zip, T7GF3B.zipand later combined into T7GFIX3.zip.
Perhaps T7GFA and B were released separately, but I don't have those details. What's important though is to figure out what's actually required for a fully-patched install of the game.
Conclusion: You do not need T7GF3A.zip or T7GF3B.zip, which some other sites seem to think should be installed before the T7GFIX3 contents. The only major difference is save.z, but this is probably also in the 1.30 patcher. You should still install the contents of T7GFIX3.zip.
To do the comparison yourself, do the following (but it's not necessary)
$ for i in T7GFIX3 T7GF3A T7GF3B ; do mkdir -p $i ; cd $i ; unzip ../$i ; cd .. ; doneYou might notice that both T7GF3A.zip and T7GF3B.zip contain versions of INSTALL.EXE and V.EXE, but a quick Simple File Verification with your tool of choice will tell you that they're the same.

$ diff -r T7GF3combo T7GFIX3 Only in T7GF3combo/: README.TXT Only in T7GF3combo/: READTHIS.NOW Only in T7GF3combo/: SAVE.Z Only in T7GF3combo/: T7G.BAT Only in T7GF3combo/: T7GDEMO.BAT Only in T7GFIX3/: T7GFIX3.TXT Files T7GF3combo//V.EXE and T7GFIX3//V.EXE differSo lets take a look at the differences. README.TXT is a copy of the original Readme which shipped with the game, and READTHIS.NOW is an advert for the BBS which must have hosted the files at some point. (If you haven't seen the excellent BBS: The Documentary, then go and get hold of a copy and learn something new about internet history. I'll put a copy of the BBS advert at the bottom of this post.
T7GFIX3.TXT announces a new version of V.EXE which "only requires 450K of memory". We'll bear this in mind later.
So that leaves the batch files, which contain:
$ cat T7GF3combo/T7G.BAT @v ! $ cat T7GF3combo/T7GDEMO.BAT @v @
So they both call v.exe, one passing arguments, the other dropping them(? I'm not going to spend any time looking up what they actually do, I have no interest in learning Dos / Batch )
On to SAVE.Z, which only exists in the separate version of the patching. I don't know what its function is. I know that later patches enable "Open House" mode, which allows access to all the puzzles but without the Adventure aspect of the game. Perhaps this is an early release of this, that they left out of the combined patch(?) Here are the contents:
$ hexedit T7GF3combo/SAVE.Z # for lack of a better tool $ # (copy and paste the contents ...) 00000000 11 12 1F 22 24 15 14 10 17 11 1D 15 F4 00 00 00 00 00 00 00 00 00 00 00 ..."$........... which doesn't mean much to me.
This leaves two versions of V.EXE, on top of the one installed direct from the CD. For reference, I'll include the output of my VERSION.BAT which, if it does what it claims, is a pretty nifty idea that many other games could have done with (I may also update the article with details of the post-patch install's version of v.exe).

So there we have it -- the only effective difference between installing the separate patches first, and then the later release is that you end up with Save.z. I don't know what it does, but I'm willing to guess that it's Open House mode which the later 1.30 patch will install anyway.
