Unpack those .EXE game files from GOG,com (Plus other un-packers)

I just came upon innoextract today. I have many of the wonderful games from GOG.com, some of which have native Linux Clients. Before now, I've had to use PlayOnLinux or Crossover to install these for use with WINE, then add the Linux client.

InnoSetup as a way to create an installer to install the games on Windows. Daniel Scharrer has created innoextract to allow the unpacking of those archives on a non-Windows platform.

The website provides information on using innoextract, but this information from the page is very useful:
GOG.com Installers
GOG.com installers with a 2.x.x version number on the download page or in the filename use InnoSetup 5.5.0 and cannot be extracted by innoextract 1.2 and older. Older installers use InnoSetup 5.2.3 and usually have no version in the filename.
Some GOG.com multi-part installers with version 2.1.x or higher use RAR archives (renamed to .bin) to store the game data. These files are not part of the InnoSetup installer and require unrar or unar to be installed, as well as  innoextract 1.5 or newer and use of the --gog option.

A Windows only version has more features; it is also Open Source.

MORE ARCHIVE UNPACKERS

1. unshield can be used to extract cab files from InstallShield installers and cabextract can be used to extract files from cab files. msitools can be used to inspect and build Windows Installer (.msi) files.

2. fsarchiver is a system tool that allows you to save the contents of a file-system to a compressed archive file. The file-system can be restored on a partition which has a different size and it can be restored on a different file-system. Unlike tar/dar, FSArchiver also creates the file-system when it extracts the data to partitions. Everything is checksummed in the archive in order to protect the data. If the archive is corrupt, you just loose the current file, not the whole archive.

3. makeself is a packaging tool used to make installers. It is a small shell script that generates a self-extractable compressed tar archive from a directory. The resulting file appears as a shell script (many of those have a .run suffix), and can be launched as is. Here's a HOWTO.

4. With UT2003 update 2199, a umod unpacker function was included with Unreal Tournament 2003.
Added a "umodunpack" commandlet to ucc, to extract ut2mod files.
   Usage:
     to extract:
      ./ucc-bin umodunpack -x file.ut2mod -nohomedir
     to list contents of file.
      ./ucc-bin umodunpack -l file.ut2mod -nohomedir
5. Microsoft .msi files can be unpacked using 7zip, but it cannot de-compile that data files, so it maybe not of much use. lessmsi can be used to extract files from .msi files.

6. cabextract can be used to unpack Microsoft .cab files.

DOS4GW.EXE Version 2.01a and Alternative DOS Extenders

DOS4GW.EXE
The TenberryDOS extender DOS4GW.EXE was used by many early DOS games. I still enjoy playing many of these games and DOS4GW.EXE is usable with DOSBox, so they can be played on Linux.

However, the version of DOS4GW.EXE that was included with the game was whatever was current at the time. The most recent version that includes many bugfixes that possibly affected the games when used with DOSBox have been fixed in the latest version, 2.01a.

It's not free at US$49, but you can downloaded it here. Simply substitute it for whatever version of DOS4GW.EXE your game provided and enjoy the bug-fixed goodness. Tenberry also makes a "high-performance" "pro" version of DOS4GW.EXE, but it costs $300. I think that they could sell quite a few of these to hobby users (since, you know, DOS is dead) for US$5.

Fixing a Buggy ACPI BIOS Updated for Windows 8 and Linux Kernel 3.x

In the BIOS, there is a table that configures/determines a number of hardware values for ACPI and your system to use.

One of the features of ACPI is that the values and methods used can be differentiated at boot time depending on what OS you run. Each version of MS Windows has a unique identifier and while Linux can identify as "Linux", the Linux ACPI gurus have decided that Linux will always identify itself as "Windows NT". Even if you force Linux to identify itself as Linux, the Linux ACPI code still lies to the BIOS, except for the computers specifically listed in drivers/acpi/blacklist.

If you are running very new hardware intended for Windows Vista or Windows 8, you might get better performance on ACPI-related issues if you identify, or "spoof", your Linux OS as Vista or Windows 8. This is done by adding the boot-time kernel parameter of acpi_osi="Windows 2006" or "Windows 2012" respectively (and the quotes are necessary). still,…

Unreal Tournament GOTY/UT99 for Modern Linux

Released on November 16, 1999, Unreal Tournament (also known as UT99) is an arena first-person shooter for Multiplayer on-line competition or you cam play against bots off-line. It features several game types, with more details provided at Wikipedia. The game was re-released on February 25, 2000 as Unreal Tournament Game of the Year Edition (GOTY) which included the three bonus packs released previously and additional mods, or game modifiers that had become popular. It is the GOTY version that is available from STEAM of GOG.com.

The GOG version for Windows installs in Linux and plays well using WINE, PlayOnLinux or Codeweaver's Crossover.

There is a Linux binary available in two versions, one for the original game and one for the GOTY edition. Also provided at that site is the Official Bonus Pack with a Linux installer. All these Linux installers are created with makeself.

There are some issues using such a crusty old Linux binary. Let's see why getting a Linux binary up and …
