Opera Portable

Hi, I prefer to use Opera as internet browser. I use Opera@USB by Markus Obermair (http://www.opera-usb.com) but I prefer it to be in the same folder and to use the same Portable Apps menu as other Portable Apps do (now it's impossible). I dislike Mozilla Firefox Portable because of its very slow work: it works like tortoise from my flash drive (without any extensions). Opera works much faster. Thanks.
