EGBrowser Lite is dial-up only, and regular EGBrowser is also likely the same way.
EGBrowser BB seems to be the only version that supports the HDD, but doesn't require it. It uses 128 MB of the HDD as a cache for recently viewed websites, and requires a broadband connection.
There is no English patch for it that anyone has brought to my atttention, although a manual/guide for it in English is on my list of things to do. I'm still working on sections of the PSBBN guide though, as that is easier to obtain, and more people have given me feedback that they are actually using the software.
EGBrowser is just an updated version of the Dreamcast web browser. It has support for more file types, but since it came out in 2002 and hasn't been updated since, it doesn't work properly with some current websites.
