here was something I hacked together when Dave and I
were comparing ROM versions. catenate the images together
and it will print out any bytes that differ
#include <stdio.h>
main(){
FILE *f1, *f2;
unsigned char c1, c2;
unsigned int adr = 0;
f1 = fopen("el2_prom","rb");
f2 = fopen("el_prom","rb");
while(!feof(f1)){
c1 = getc(f1);
c2 = getc(f2);
if (c1 != c2){
printf("%04x %02x %02x\n", adr, c1 ,c2);
}
adr++;
}
}
..not pretty but it got the job done
