Amateur. Use Flashget or Netants which download the file in 8 simultaneous chunks. I used to cheer the threads on last legs of a whopping 5m download. I hated servers which dont allow resume or even report file size.

If I remember correctly, unfortunately the HTTP server hosting Liero back then didn't support requests with the Range header.

But also likely I didn't have FlashGet on my cousin's computer which was the computer we were using to play it.
