The targets allow to run cc65 programs in the sim65 exection einvironment. As there are no "real" i/o facilities there's no need for header files. Paravirtualized entry points are mapped to $FFF0 ff. There's a large cc65 progam area from $0200-$FFEF. The binary format includes a one-byte header indicating the required execution environment: The value 0 means 6502 and the value 1 means 65C02. The load adress for the binary is fixed to $0200. Note: Running sim65C02 programs currently doesn't work bcause sim65 doesn't actually implement 65C02 opcodes.
