Sierra Game Versions

Revision as of 04:55, 4 December 2010 by Clone2727 (talk | contribs) (cleanup)

The list is sorted on interpreter version, except for the ancient AGI0 and AGI1 interpreters, since they do not use proper version numbering!

File dates are not used. This only deals with PC versions of the games.

Based on this document. Used with permission.
PASSIGAR also has a very good list of almost all known Sierra game versions

AGI Games

AGI0 & AGI1 were originally available on:

  • IBM PC (including PCjr & TANDY)
  • Apple ][

AGI2 & AGI3 were originally available on:

  • IBM PC (including PCjr & TANDY)
  • Apple ][ / Apple ][GS
  • Apple Macintosh
  • Atari ST
  • Coco 3 (TRS-80 Color)
  • Commodore AMIGA

No official translations known.

If a game is marked with an * it means that the game has been shipped on both 3.5" & 5.25" disks, meaning the same version spread over more/less VOL files.

Example:

Gold Rush! 2.01 - 3.5" Version Gold Rush! 2.01 - 5.25" Version
GRVOL.0 78.086 bytes GRVOL.0 25.070 bytes

SCI Games

SCI games were originally available on:

Platform SCI0/SCI01 SCI1/SCI11 SCI32
IBM PC Yes* 286+ 386+
Apple Macintosh Yes Yes Yes
Atari ST Yes No No
Commodore AMIGA Yes Yes No
Fujitsu FM-Towns No Yes No
NEC PC-9801 Yes Yes No

* - Including PCjr & Tandy

This table will show information about translations/international versions:

Interpreter Foreign Version Language Known Suspect Notes
SCI0 None None None No unicode support
SCI01 Bilingual FR/GER JAP Converted SCI01 games
SCI1 Bilingual FR/GER/IT/SP None
SCI11 Standalone FR/GER/IT/SP/PT JAP Only RESOURCE.MSG differs
SCI32 Standalone FR/GER/IT/SP/PT JAP Sometimes subtitles only

There are no real SCI0 translations. This is because this interpreter does not cover special characters like accent grave, accent egu, umlaut, etc. The SCI0 games that are translated are converted to the hybrid SCI01.

All the SCI0(1) games are released on both 3.5" & 5.25" disks, except XMAS Card 1988, Astro Chicken & Fun Seeker's Guide, which of course were public domain.

All the games listed are disk versions unless noted otherwise.

SCI1 games were released as two versions: 16 color EGA and 256 color VGA versions. The 16 color versions are a lot "uglier" and also smaller in size, compared to their 256 color counterparts. This was done for people with CGA/EGA/TANDY video cards and a low-memory setup. SCI11 ended this tradition by adding a EGA graphics driver.

SCI2, SCI21, and SCI3 can be collectively referred to as SCI32 because the released original interpreters were 32-bit executables.

x.yyy.yyy is clearly a standard value, so these game do have different interpreters. The games which share the same interpreter are grouped by separating different versions with a blank line.

Not SCI

  • Shivers II (game and demo): Does not contain SCI scripts, the room logic has been rewritten in native code placed in DLL files
  • Leisure Suit Larry 6 (demo): Not SCI, it's a collection of PCX screenshots played with an external player
  • Space Quest V (demo): Not SCI, it uses Dynamix' DGDS engine
  • Betrayal in Antara: Not SCI. It has SCI resources for the 2D parts (e.g. inside buildings), but it has its own script system, plus a 3D engine
    • For extra fun, some of Antara's "ETC" resources are really Doom PWAD files (the true SCI+Doom mashup).

Possible Entries

The following games are likely/known to exist:

AGI

  • Gold Rush! (Re-release without copy-protection, limited edition)

SCI0

SCI1

SCI11

SCI32

  • (Whole bunch of foreign games)

Unknown

Exclusions

These games are not AGI or SCI (but some are related to Sierra):

Revolution Games

Other Genre Sierra Games

  • 3D Helicopter Simulator
  • Oil's Well (Remake)
  • Johnny Castaway Screenantics (Screensaver)
  • The Laffer Utilities
  • The Incredible Machine Games
  • Lode Runner: TLR
  • (etc.)

Only the demo of 3D Helicopter Simulator included in a demo-pack uses AGI. Most of these titles often have the usual filenames (RESOURCE, etc.) but they do not use the AGI/SCI interpreter.

Early Sierra CD Titles

Same as disk versions.

Post-1997 Sierra Games

  • Gabriel Knight 3
  • Quest for Glory V
  • (every Sierra game after '97)

After 1997, the SCI engine (and pretty much the adventure genre in general) was abandoned.

Other AGI/SCI Games

  • Most Russian Translations
  • Every Chinese Translation
  • Every AGI Translation
  • Every SCI0 Translation
  • Certain SCI1+ translations

Most (all?) of these are all hacks. It is unknown about later (SCI32) Russian ones, as some say they were indeed translated and sold officially.

Notes

  • Donald Duck's Playground PC was OFFICIALLY released on a booter, version 1.0Q, combined with AGI v2.001! The 1.0A and the 1.0C version floating around are "hacked" copies. 1.0A is an Atari ST version, combined with an 2.272 PC interpreter and has no sound & menu. 1.0C is an Amiga version, which uses the same interpreter as 1.0A and pushing ESC (to access the menu) results in "Bad action 161".
  • The Russian AGI/SCI games are all (pretty well done) hacks. NEWSCIV is infact an regular SCI interpreter, but with some intro (Taralej & Jabocrack SoftWare presents) attached to it.
