These files, used by the PC64 emulator, are simply the BASIC, KERNEL and
|
|
CHARACTER ROM's in electronic form. There contain no signature, but rather
|
|
are raw binary dumps of either the ROM's contained in the C64 computer, or
|
|
other customized ROM's.
|
|
|
|
There are three different files, denoted by the change in the last
|
|
character of the file extension...
|
|
|
|
64B - BASIC ROM ('B'), This is the ROM from $A000-BFFF, which contains
|
|
the BASIC interpreter. It is always 8192 bytes.
|
|
64C - CHARACTER ROM ('C') This is the ROM from $D000-DFFF, which contains
|
|
the character sets. It is always 4096 bytes.
|
|
64K - KERNEL ROM ('K'). This is the ROM from $E000-FFFF, which contains
|
|
all the KERNEL calls and I/O routines. It is always 8192 bytes.
