Hitchhiker Guide to the Galaxy text adventure
 
TRILLIAN / PHOBOS (DOS PATCH for HitchHiker's Guide to the Galaxy and Leather Goddesses of Phobos)

Reqs:   Preferably MSX2 with 64ks RAM, so it can use 80 columns text display


TRILLIAN.COM/PHOBOS.COM allows you to play HITCHHIKER'S GUIDE TO THE GALAXY game or LEATHER GODDESES OF PHOBOS game under MSX-DOS without the problem of the system cleaning the screen after every text is written.
 
This happens cause the games are for CP/M Plus (aka CP/M 3), while our loved MSX-DOS is only compatible with CP/M up to version 2.2. CP/M Plus has some escape sequence that doesn't work the same way on MSX-DOS and deletes the screen.
 
Of course you can play with the original files if you use the existing CP/M Plus for MSX. But it's not that handy, specially when on MSX-DOS2 you can have the files on a directory on your SD/MMC/CF card easily.
 
So, those patches solves this. They doesn't patch the games in any way, but the DOS hook itself. This way it avoids the sequence escape when the text DOS printing routine is called from the game.
 
They also allow configure some extras, like screen colors, font or function key text.

More info on the README texts inside the package.


IMPORTANT NOTES!

The patch doesn't changes the original files in any way. It only patches the MSX-DOS hook to jump to the patching routine when needed.

To play Hitchhiker's Guide to the Galaxy game or Leather Goddesses of Phobos game, you will need the original files from these games, as they're not provided.

For HHGTTG those files (original CP/M game) are:
 
HITCH.COM
HITCHHIK.DAT

for LGOP, those files (original CP/M game) are:

LEAT128.COM
LEATHER.DAT
 
I found some more files (taken from an Amstrad CPC disk), called
 
LEAT256.COM
LEAT64.COM
LEATHERG.COM
 
but they're not necessary, it seems.


Below you can see some screens running the game WITHOUT the patch and WITH the patch.
