*** 64x (PC64/DOS ROM files) *** Document revision: 1.1 *** Last updated: March 11, 2004 *** Contributors/sources: Wolfgang Lorenz 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.
