What i found!?

[knuck]

 function openFlashClient(resolution, factionID)
    {
        try {
            if (typeof(window.opener) == 'object' && window.opener.thisIsReal) {
                window.opener.focus();
                return;
            }
        } catch (e) {}

        if(playerWantsOldClient) {
            // open client in old-fashioned way...
            var map = 'internalMap';
        } else {

            var map = 'internalMapRevolution';

i found this in tech center page source what is that doing there? and how to use it? Because
doesn't work ;(

This do nothing because OldClient is disabled.

Here is what it do:

[Prime.™]

function openFlashClient(resolution, factionID)
{
try {
if (typeof(window.opener) == 'object' && window.opener.thisIsReal) {
window.opener.focus();
return;
}
} catch (e) {}

if(playerWantsOldClient) {
// open client in old-fashioned way...
var map = 'internalMap';
} else {

var map = 'internalMapRevolution'


If you Erase InternalMapRevolution
You will get Old client



Joke
Its source code of Disabling Old client

I think this is the option that BP put in the game when the v2 client was in "beta".
