For US or other countries you may need some tweaks. For US,
In = FALSE
Out = TRUE
Key = "URL: PS3 firmware check hack [OUT]"
URL = "*.ps3.update.playstation.net/update/ps3/list/eu/ps3-updatelist.txt$RDIR(http://file//C:/ps3-updatelist.txt)"
text "eu" to "us"
Also, for: http://220.127.116.11/update/ps3/list...updatelist.txt
change "eu" to "us" and it will get the proper file for you.
