- INTRODUCTION
-
-
- fakecd is a program that simulates a CD-ROM drive with a directory of
- a hard drive. Its intended purpose is to allow running of CD-based
- software entirely from a hard drive. This gives you the following ad-
- vantages:
-
- 1. speed: Hard drives are much faster than CD-ROMs. If you need much
- data from your mass storage device in a short time your
- CD-ROM may be a bottleneck. This can result in "slide shows"
- in certain games. However, your CPU horsepower or your
- video interface may be the problem if a CD-based program
- is slow. With fakecd you can eliminate one potential bottle-
- neck and watch how the program runs with a very fast "CD-ROM
- drive".
-
- 2. memory: You don't need to load a CD-ROM driver or MSCDEX for fakecd
- to work (although they can coexist). If your program needs
- much conventional memory this may allow you to run the pro-
- gram at all.
-
- This is the first public release of the program. It is public domain.
- It was tested with MS-DOS 6.0 and Novell-DOS 7.0 and some CD-based
- games. It works in Windows 3.x since these Windows versions use DOS
- services to access the CD-ROM. It was not tested with OS/2 or
- Windows 95. The worst thing that could possibly happen is that you are
- unable to access some drives after fakecd was installed. Uninstalling
- fakecd should remove the problem. If not, a simple reboot will work.
- Since fakecd does not write anything to any drive, it will NOT corrupt
- any data on your hard disks.
-
- An (almost identical) beta version of this program has been tested by
- some people with their games, including "Mortal Kombat II", "Dark
- Forces", "Virtual Pool" and "Legend of Kyrandia I and III". There
- were no problems reported.
- If you find any problems with fakecd (does not install, does not uninstall,
- gives wrong error messages, ...) send an e-mail message to

- HOW TO USE
-
-
- First, you must copy the content of your CD-ROM to a directory on your
- hard disk. You may use any file managing utility or the DOS xcopy command:
- xcopy e:\ c:\prog-cd /s /h
- where e: is your CD-ROM drive and c:\prog-cd the destination directory.
- Then you must run fakecd. fakecd is a TSR (memory resident) program. It
- will need some 9K of memory during installation and less than 2 KB during
- operation (including environment) and can be loaded high (with command
- "lh fakecd ...").
-
-
- The syntax of the fakecd command line is
- fakecd /H[elp] | /? | /U[ninstall] | DIRECTORY [/L:x]
-
- /Help and /?
- will give you a short description of each option.
-
- /Uninstall
- will remove a previously installed fakecd from memory. This may be
- impossible if some other TSR program was installed after fakecd. You
- can have only one copy of fakecd resident in memory at one time. If you
- want to use fakecd with other parameters, you must first uninstall the
- old copy of fakecd and then install the new one. If you have several
- CD-based programs on your hard drive you can make batch files like
-
- c:\utils\fakecd c:\prog1-cd /l:e
- e:
- prog1
- c:
- c:\utils\fakecd /u
-
- This will load fakecd and simulate the directory c:\prog1-cd as CD-ROM
- drive E:. After the execution of prog1 the resident copy of fakecd is
- removed. You can later execute another copy of fakecd to simulate the
- same directory in another drive or a completely different directory.
-
- DIRECTORY
- is the name of the directory that will be the root directory of the
- simulated CD-ROM drive. It may be specified as a full path
- (c:\games\kyr1-cd) or as relative path (..\kyr3-cd). The drive on
- which the directory resides should be a local hard disk. It should
- work with a compressed drive (tested with Stacker) but will probably
- not work with a network drive. This is due to the mechanism used by
- fakecd to make the directory look like a drive to DOS.
-
- /L:x
- gives the drive letter (x) for the simulated CD-ROM drive. x must be in
- the range from A up to the drive specified with LASTDRIVE. It should be
- an unused drive since if your simulated CD-ROM will be C: you will not
- be able to access any files on your hard drive C: (which will probably
- include your DOS commands, COMMAND.COM and maybe fakecd).
- If there is no /L:x parameter, fakecd uses a default value for x.
- If MSCDEX is installed, x will be your first CD-ROM drive letter. If
- MSCDEX is not installed, x will be your first unused drive letter.
-
- I recommend that you always use the same drive letter for your CD-ROM.
- Some programs are run directly from the CD and have some configuration
- files on a predetermined place on your hard disk (most often on drive c:).
- These programs should not worry if they are started from different drive
- letters each time you run them. Other programs copy a small number of
- files to your hard disk at installation time and one of these files must
- be executed to start the program. This way they can store config files and
- (in case of games) savegames to a user selected place on the hard disk.
- These programs must find the CD-ROM drive with their CD in it. Some programs
- (Legend of Kyrandia series) use CD-ROM specific methods to find the CD-ROM
- drive and they work with fakecd if started from different drive letters each
- time they are run. Other programs (Monty Python's CWOT and Dark Forces)
- store the drive letter from which they were installed. If you start them
- with fakecd from a different drive letter they will not find their data and
- refuse to run.
-
-
- CD-AUDIO
-
-
- Some games use audio tracks for music. This music is not in a computer
- readable form. It was not copied to the hard disk with the other files
- and it can not be done (at least not in a form useful for fakecd). So you
- will not hear that music. fakecd will however make the program believe that
- everything is fine. (Note: I could test this feature with only one program.
- So I need desperately feedback about programs that use audio tracks and
- how they work with fakecd!)
-
-
-
- I hope you will find fakecd a useful program. If you have comments,
- suggestions or bug reports, then send me an e-mail and I will (try to!)
- correct any errors.
