Hey Hey,

I'm not sure what you're changing, but once you answer TS (this time I mean Tiger Shark )I'll have a better idea. Anyways, to make a change to a binary file you should use a hex-editor.

As for your second question, that's an easy one, well kinda. Remember a few years back when the big thing on IRC was to hex edit your version response, so that people couldn't find out you were using mIRC? Well all you had to do was open mIRC.exe in your favourite hex editor and search for version then replace the version string "mIRC 4.11 blah blah blah" with blanks. As long as you kept the string the same size, you were fine, but if you made it bigger (increasing the size of the program) it would crash out. I'm not entirely sure why this happens, but I believe the file knows it's size, or byte locations or something (or at least that's what I tell myself).. Certain hex editors, i.Hex for one, are looking at implementing the ability to add/delete bytes from a file however I'm not sure if anyone has succeeded yet.

Peace,
HT
