Temporarily, you could make a BAT File..
PHP Code:
start Localhost.exe 127.0.0.1 8484
Other then that, yeah v62 localhosts and below has a completely different encryption and therefore is unable to be loaded via STREDIT.
Also, I think the port is actually a packet, not an ASCII string. Because 8484 isn't 8.4.8.4, 8..4..8..4, etc. to be read.
It might be some packet like 38 34 38 34 (i think thats "8484"?) or something.
Why bother changing the world port? Just change your channel ports if you really need too. If your hosting two servers then just have a v75+ server.
If i'm wrong, please correct me.
