+=== 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.

 This is another old book that describes how to use GCC (and period assembler and linker, such as HAS, as listed way down this page) to develop game software on the X68000.

+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!!!

 Pre-built binaries for Linux:

 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:
