Using [kernalemu](https://github.com/mist64/kernalemu) and [cbm6502asm](https://github.com/mist64/cbm6502asm), almost all source in this repo can be built from the UNIX command line. To build everything, run `build.sh` from the Unix command line, on a case-insensitive filesystem.

* the [BSO-format SRC from 1987](http://www.zimmers.net/anonftp/pub/cbm/src/c64/c64_kernal_bas_src.tar.gz)
There are two differences though:
* In both sources, the added patch function `PIOKEY` ends with `JMP CLKHI` ($EE85), but the -03 binary contains $EE8E, which is `JMP CLKLO`. The change was probably done in the binary and not added back to the source. The version in this repository contains the correct `JMP CLKLO` though.
* The printout LST contains a version byte ($FF80) of 0, the VAX SRC contains the correct version byte of 3. The version in this repository contains a 3.
* The printout LST contains a version byte ($FF80) of 0, the BSO SRC contains the correct version byte of 3. The version in this repository contains a 3.
The sources have been verified to build the correct -03 KERNAL binary.
It contains the version byte (3) at $FF80, but it does not contain the "RRBY" signature at $FFF6.

* BASIC_C64GS: The source has updated comments, and the binary is identical with the regular C64 BASIC, except for:
* The BASIC vector table is initialized with a literal $F72E as the main loop address. This causes BASIC to jump to the C64GS power-on message in the KERNAL.
