<title>Gamate System specific information for cc65

||||
<abstract>
|
||||
An overview over the Gamate runtime system as it is implemented for the
|
||||
cc65 C compiler.

|
||||
|
||||
<sect>Overview<p>
|
||||
|
||||
This file contains an overview of the Gamate runtime system as it comes
|
||||
with the cc65 C compiler. It describes the memory layout, Gamate specific header
|
||||
files, available drivers, and any pitfalls specific to that platform.
|
||||
|
||||
Please note that Gamate specific functions are just mentioned here, they are
|
||||
described in detail in the separate <url url="funcref.html" name="function
|
||||
reference">. Even functions marked as "platform dependent" may be available on
|
||||
more than one platform. Please see the function reference for more
|
||||
information.
|
||||
|
||||
|
||||
<sect>Binary format<p>
|
||||
|
||||
The standard binary output format generated by the linker for the Gamate target
|
||||
is a cartridge image with header. It is of course possible to change this
|
||||
behaviour by using a modified startup file and linker config.
|
||||
|
||||
<sect>Platform specific header files<p>
|
||||
|
||||
Programs containing Gamate specific code may use the <tt/gamate.h/ header file.
|
||||
|
||||
|
||||
<sect1>Hardware access<p>
|
||||
|
||||
The following pseudo variables declared in the <tt/gamate.inc/ include file do
|
||||
allow access to hardware located in the address space.
|
||||
|
||||
<descrip>
|
||||
|
||||
</descrip><p>
|
||||
|
||||
|
||||
|
||||
<sect>Loadable drivers<p>
|
||||
|
||||
All drivers must be statically linked because no file I/O is available.
|
||||
The names in the parentheses denote the symbols to be used for static linking of the drivers.
|
||||
|
||||
|
||||
<sect1>Graphics drivers<p>
|
||||
|
||||
No TGI graphics drivers are currently available for the Gamate.
|
||||
|
||||
|
||||
<sect1>Extended memory drivers<p>
|
||||
|
||||
No extended memory drivers are currently available for the Gamate.
|
||||
|
||||
|
||||
<sect1>Joystick drivers<p>
|
||||
|
||||
<descrip>
|
||||
|
||||
<tag><tt/gamate-stdjoy.joy (gamate_stdjoy)/</tag>
|
||||
A joystick driver for the standard two buttons joypad is available.
|
||||
|
||||
</descrip><p>
|
||||
|
||||
|
||||
<sect1>Mouse drivers<p>
|
||||
|
||||
No mouse drivers are currently available for the Gamate.
|
||||
|
||||
|
||||
<sect1>RS232 device drivers<p>
|
||||
|
||||
No serial drivers are currently available for the Gamate.
|
||||
|
||||
|
||||
|
||||
<sect>Limitations<p>
|
||||
|
||||
<itemize>
|
||||
<item>interruptor support in crt0 (and cfg) is missing
|
||||
</itemize>
|
||||
|
||||
<sect1>Disk I/O<p>
|
||||
|
||||
The existing library for the Gamate doesn't implement C file
|
||||
I/O. There are no hacks for the <tt/read()/ and <tt/write()/ routines.
|
||||
|
||||
To be more concrete, this limitation means that you cannot use any of the
|
||||
following functions (and a few others):
|
||||
|
||||
<itemize>
|
||||
<item>printf
|
||||
<item>fclose
|
||||
<item>fopen
|
||||
<item>fread
|
||||
<item>fprintf
|
||||
<item>fputc
|
||||
<item>fscanf
|
||||
<item>fwrite
|
||||
<item>...
|
||||
</itemize>
|
||||
|
||||
<sect>Other hints<p>
|
||||
|
||||
<itemize>
|
||||
<item>a good emulator to use for Gamate is "MESS/MAME" (<url url="http://www.mess.org/">)
|
||||

||||

||||
