All you have to do is look :
sub hexdump {
my ( $this, $from, $len ) = @_;
return "Err: length is too long!" if $len > 65536;
He apparently restricted the len to 16 bits for some reason.
You can try :
1) Changing the 65536 to 2 ** 32 (or maybe somewhere in between).
or
2) Add another loop in your code to loop over 65K at a time -
something like this untested code:
my $len = $memlist{$_};
my $bytes = $len > 65536 ? 65536 : $len;
for (my $off = 0; $off < $len; $off += 65536) {
print OUT $proc->hexdump($_+$off, $bytes) . "\n";
$bytes += 65536;
}
