I don't think that things/patches you are doing looks like "retail" to sad news :(
If you had played on retail you would know from c4 onwards all players ran these patches? Lineage 2 Media patches were the bomb back in the day (some useful such as the drop/spoil patch, some funny such as the nude patch and some gamebreaking such as the wallhack/wireframe mode). They were also all legal as no client modifications (added that to cover the inevitable "but 90% used bots and tower back then, those were "illlegal" but ncsoft did very little about them).
That's my argument for asking for them but making sure wireframe is left out on another thread since it is an unfair advantage.
