UniSCI with source code!

26/07/2013

After a while from its birth, the UniSCI tool will finally have the page that it deserves! Hidden in the core of the GK2 DVD installer (and also installers for other SCI games, developed by other contributors to the SCI community) this is one of the smartest pieces of C++ code that I ever made in a rush.  Basically, it has to load all data from the 6 CDROMs of the game, join all that stuff, and save it to one big data file. Everything is done automatically — so that the end user feels that it’s just glueing the 6 files together — but there’s a lot of work under the hood.

I still remember when this tool was just sitting in a corner of my mind waiting to be coded. Development took about two weeks of hard work, testing and fixing. There was no documentation about the file formats involved. It was a job about reverse-engineering, disassembling… sometimes even wild guessing!  Luckily, I had no boss limiting my working schedule. At the end, the tool happened to be pretty reliable. Later, it was used even for joining games which it was not conceived for, and I still wonder how that was possible without any debugging involved. Anyway… there are still things to fix, to investigate… as I’ve just been told that the tool is not working for the most recent SCI games.

So I hope that somebody will continue this project from where I left it.  He’ll probably need to learn Italian to understand the comments in the source code.  🙂   Or… he will ask me and I’ll dig into those old days code-adventuring memories.  And I’ll be glad to!

A.SCI (assembler for SCI1.1/SCI32)

19/06/2009

A.SCI, the first Assembler for the Sierra Creative Interpreter versions 1.1 and 2 (SCI32), entirely written in C++.

IMPORTANT NOTE: This is not a compiler; basically, it’s a disassembler with an assembler to reverse the process, which allows for minor changes to games. Use at your own risk! Double check your game after doing deep modifications to it!

MacSCI Utils

16/06/2009

This is a package of utilities that was part of my old Quest for Glory 4 on Mac project. Basically these utilities should allow conversion from the PC version of the game data, to the Mac format, which is different in many things. This project was never brought to completion due to the pointlessness that it gained when DosBox came out, allowing for a perfect emulation of DOS games. I’m releasing now all the stuff, sourcecode included, just as a curiosity.

Quest for Glory V noCD update for Mac

16/06/2009

This is an update that I made back in 2006 to avoid keeping CDRoms in the drive while playing. It was also an experiment on PPC assembly.

DISCLAIMER: to be used only with a legal copy of the game! I do not endorse piracy! If you do, you’re the only responsible.

SCI Resource Dumper modded 1.2.3

16/06/2009

SCI Resource Dumper 1.2.3 is able to extract data from SCI1.1 and SCI32
Sierra games other than Eco Quest I and Police Quest I (VGA). The program is copyright Vladimir Gneushev, but I have changed this version in order to support other SCI1.1 games like Quest for Glory I (VGA). Minor bugs were also fixed (more info in the sourcecode).

SCI Decoder VGA modded 1.1

16/06/2009

SCI Decoder VGA 1.1 is used to extract and display data from Police Quest I (VGA), Eco Quest I and other SCI games. The version here posted is not the original one by Carl Muckenhoupt. I changed a few lines of code to support Police Quest. I’m not sure if this breaks compatibility with earlier games, however Eco Quest I still works fine.

Space Quest IV patch for Mac

16/06/2009

This is a patch that I made back in 2002. It is meant to solve the following problems when trying to play SQ4 on recent MacOS versions.

– The game was forced to run in 24 bit addressing mode, like oldest system did. It no longer crashes when started up.
– Time was not correctly handled by the KGetTime function which made a wrong use of the OS Time variable.

To use this program, simply drag it into your Space Quest IV game folder and run it.

Space Quest III patch for Mac

16/06/2009

This is a patch that I made back in 2002. It is meant to solve the following problems when trying to play SQ3 on recent MacOS versions.

– The game was forced to run in 24 bit addressing mode, like oldest system did. It no longer crashes when started up.
– Time was not correctly handled by the KGetTime function which made a wrong use of the OS Time variable.
– The required color depth to run was forced to 4 bit (16 color).

Also, I’ve found that there’s no sound driver capable of sounding out on Power Macintoshes. This bug has not been solved (yet).
