HexonRe: HexonSun Dec 20 19:52:40 1998 Hi JeffThe reason I NOOPed the other jne was because it immediately followed the serial checking function and I thought if the prog jumped, then it would jump outside of the registering routine. When I tested CYT using the correct reg number and traced it through in ICE the prog never jumped at this point; yet when using an incorrect reg number it did. It appeared to me that the prog must not jump at this point, so I played safe by ensuring that it did'nt. Maybe I miscalculated that jump.I'd appreciate it if you could shed any light on what the reason for that jump is. The conditional jump that I refer to is at 0043fa1f. Hexon
