Online PS2 games

[Afterlife]

I was wondering if its possible to play backups on sonys online service? I plan on getting Return of the King, and SOCOM II, but i dont own a network adaptor, and wont be buying one if backups dont work online as my ps2 has a tendancy to mistreat my originals when running them

So if anyone knows if backups can play online, or if there are patches to let them play online or any way I can do this, as there have been a few online games i have felt like testing.

Appreciate any information.

Also does anyone know when the GBA emulator for ps2 is going to be done, or if its finished and out there somewhere???
