"The Rom is not avalible to your computer"

[Blakren]

Every time I want to join a SSb game it says this. How can I change this?

download the rom, check if the name of the rom is the same as the one you are trying to join.
refresh your rom list, by pressing F5 in pj64k. and in options make sure the rom folder is set to where the rom actually is.
i cannot link you to the rom as it is illegal and not allowed here.

Make sure you've got Super Smash Bros. (U) [!]

if you're playing with the European or Japanese ROM, or if you have the version without that exclamation point, redownload the correct ROM.
