f1gp.library is a small library which provides a small number of functions
for programmers which allow detection of F1GP and notification of a number
of different events (e.g. when F1GP exits). There is also a function which
can calulate the correct file checksum.
The library also performs various patches on F1GP automatically, including
making the game use the VBR, making the game use the faster graphics fetch
modes of the AGA chipset and the ability for the game to run using 31kHz
screenmodes (primarily to support VGA monitors which cannot display PAL or
It was developed by me to aid F1GP hackers/developers and helps provide
compatibility between programs. In one of the previous registered versions
of F1GP-Ed (a long time ago) I implemented a routine to detect if F1GP was
running in memory. This was required by the new "save to memory" feature.
Then Grant and Rene popped up and I let them use the same code in their
programs. Eventually, I decided to put this routine in a shared library
which made things a lot easier and saved on memory (a little bit). That's
how it started and not a lot has changed since, except a couple of new
things. It is very easy for a program to register itself with the library
so when F1GP quits the program can act accordingly - it is common for F1GP
patch programs to need to know when F1GP quits (at the instant it happens)
to provide stability.
So, really, the library is only of use to people developing patches for use
with F1GP. I have made a developer archive available for the library which
contains further information, C & Assembler include files, examples and
full documentation. If you are interested in developing patches for F1GP
(or have already done so) feel free to let me know and I'll send you the
latest developer archive, if you need it :-) The developer files are also
available from Aminet: dev/misc/f1gplib.lha
