Thank you for pointing that out. Really. I mean it. And nothing else it is. Happy hacking. IDA anyone? (objdump does nicely, too. I looked at the disassembler output for about one hour today and my conclusion is that it's a pretty simple job. Knowing the stack concept and the "mov", "call", "lea", "add", "sub", "xor", "sar" and "sh[l|r]" instructions is enough.) I would do it if I just had the time. -- Thomas Winischhofer Vienna/Austria thomas AT winischhofer DOT net http://www.winischhofer.net/ twini AT xfree86 DOT org
