I think it might have been that I installed some of the plug ins wrong, it worked before I installed them. I installed Glide 64 ME SP5, Federelli's Nemu64.ini file, Direct 64 0.5 Alpha, and Rice's Video 5.6.0 Fix 4.
system spec
AMD athlon 2400+
128mb Radeon 9600
512 RAM
can anyone tell me how to install them the right way?
