+=== X68000 Programmers Reference ===
+Comprehensive set of programmers reference manuals covering most of the system calls, the use of (very early) GCC and GDB tools and more.

+   * Blue book (#0) covers the install and use of early versions of GCC, HAS assembler and GDB
+   * Red book (#1) covers the use of the early versions of GCC and the GDB debugger
+   * Green book (#2) covers function calls available in old versions of GCC and doscalls (including better worded descriptions compared to 'Inside X68000' or the 'PUNI docs')
+It's fair to say that #0 has more assembly examples than #2, which is probably the one you want if you are interested in figuring out how to use the various X68000 system calls in //doscalls/dos.h//.
+//Do be aware that when the various libc function calls are listed, this is referring to the old version of GCC, and not the new version which comes with newlib and a smaller set of functions.

+To be fair, the best source of material for this one is found in the example source code. Note: Disk 1 is just the old GCC compiler, the examples are found on Disk 2. You can either download the disk images and mount them in a real or emulated X68000, or download the extracted sample files so that you can view them with any normal text editor. Be aware that some of the code uses S-JIS encoded for actual function names!!!

 If you want to build the tools from source, here's a handy script that patches them with a required fix before install; you must apply the patch, as there is a bug in this version of GCC which will cause a segfault during compilation otherwise:
    * {{ :blog:build_x68_gcc.zip |}} - Run the included bash script to configure and patch the source from Github
+Note as well, that the current distribution includes some C header prototypes that cause bus errors due to struct alignment problems. This is discussed here: https://nfggames.com/forum2/index.php?msg=41392
+The pre-compiled bundle above already has the fixes applied to //dos.h//.
+==== Makefiles & Compiling ====
 Using the toolchain:
-   * Download the archive and extract in /, it unpacks to /opt/toolchains/x68k
+   * Download the pre-built binaries above and extract in /, it unpacks to /opt/toolchains/x68k
    * X68000 library functions are defined in:
      * /opt/toolchains/x68k/human68k/include/dos.h
      * /opt/toolchains/x68k/human68k/include/iocs.h
    * Use the sample makefile below
