; This is the dispatch routine to call the primary ROM 4X ; functions of intercepting RESET and the boot process. ; If one enters at $CFF9, the command $A9 is loaded and ; we go to the BELL1 hijack. If entering at $CFFA, we ; load the command $EA and proceed the same way. ; thus we get two dispatch codes in 6 bytes. .include "iic.defs" .code .org $cff9 ; 7 bytes available here, but don't count on $CFFF lda #$a9 ; lda opcode nop ; jmp/jsr $cffa does lda #$ea jmp $c7fc ; jump to 4X dispatcher ; total 6 bytes.
