Since V.0.8.0 ScummVM requires the SKY.CPT file for running Beneath a Steel Sky.
|
|
This file contains data that was originally included in the SKY.EXE and was also included
|
|
in the ScummVM executable before 0.8.0.
|
|
Including all this data in the executable has the disadvantage that it wastes memory.
|
|
Even when playing a completely different game (like, e.g. Day of the Tentacle) ScummVM would
|
|
have the Beneath a Steel Sky data lying around in memory. This doesn't make much of a difference
|
|
on a 1GB RAM windows system, but for platforms like PALM and PocketPC it's a real problem,
|
|
so this data was moved into the SKY.CPT file and is loaded at runtime when BASS is started.
|
|
|
|
This program creates the SKY.CPT file.
|
|
|
|
If you want to create your own file, *PLEASE* simply forget about it.
|
|
It's a long and annoying procedure and won't help you with anything.
|
|
This program was only included in ScummVM's source tree because the Debian license
|
|
forces us to.
|
|
Instead download the file from https://www.scummvm.org/
|
|
Also, please be aware that if you create your own CPT file (if it isn't exactly the same as the
|
|
one we offer for download at www.scummvm.org), it will be incompatible and the saved games
|
|
produced using the file will be incompatible with ScummVM using the normal CPT file.
|
|
The incompatibility will not be detected by ScummVM, it will most probably simply crash.
|
|
|
|
If you still want to waste your time by creating this file:
|
|
1) compile the tool
|
|
2) run it once, it'll complain that it's missing 7 files, the RESET.* files but
|
|
it creates an incomplete COMPACT.DBG file anyways, which you rename to SKY.CPT.
|
|
3) download the seven different Beneath a Steel Sky versions:
|
|
v.0.00288: The first floppy version that was released
|
|
v.0.00303: Another floppy version
|
|
v.0.00331: Another floppy version
|
|
v.0.00348: Another floppy version
|
|
v.0.00365: CD Demo
|
|
v.0.00368: Full CD version
|
|
v.0.00372: Final CD version
|
|
4) Apply the supplied skycpt-engine.patch to a clean copy of the ScummVM
|
|
codebase. This modifies the sky engine to allow savefiles to be generated
|
|
containing the required data for the skycpt tool.
|
|
5) Compile the patched ScummVM.
|
|
6) Start each of the BASS versions with this patched version, enjoy the intro
|
|
over and over again.
|
|
Afterwards, it'll automatically show the load/save dialog where you save the game.
|
|
7) Rename the Savegame files you created (SKY-VM.000 etc., not the ASD or SAV
|
|
file) to "RESET.*", depending on the version.
|
|
e.g. RESET.288 for v.0.00288
|
|
8) Rename each file with a ".gz" suffix and run gunzip on it.
|
|
This removes the ScummVM gzip savefile compression.
|
|
Failing to do this will cause skycpt to abort at a filesize assert
|
|
when reading the "RESET.*" files.
|
|
9) Copy the files into the skycpt tool directory, execute the tool again.
|
|
It'll create a new COMPACT.DBG.
|
|
10) Rename this file to SKY.CPT.
|
|
11) DELETE IT BECAUSE IT'S PROBABLY BROKEN, NOT WORTH BOTHERING WITH ANYWAYS
|
|
AND DOWNLOAD THE SKY.CPT FILE FROM THE URL ABOVE!!
|
|
|
|
Oh, I almost forgot.
|
|
The program only works on little endian systems and probably isn't alignment safe either.
|
|
It may also leak memory or accidentially reformat your harddisk. Who knows.
|
|
You've been warned.
