Hello,
i have a trouble with Project64 1.5 emulator (version 1.5) because it always says RSP PLUGIN ERROR.
I perfectly set all plugins but i always got that error.
How come ?
It looks like you don't have the complete PJ64 1.5 package. That would explain the missing RSP.dll and what looks like a missing RDB as well. I suggest downloading it again from the official site:
