I know you're using Windows 98 or Windows 95, because of the exact wording of the error message that appears when an application crashes,
"X
This program has performed an illegal operation and
will be shut down.
Close Details>>"
Example:
Nemu64
This program has performed an illegal operation and
will be shut down.
Close Details>> (Displays the crash information)
Possible causes:
Overclocking the processor, not enough processor voltage, Vcore,
corrupted plugin, corrupted emulator file, bad ROM dump, a ROM that got corrupted because of HDD data corruption or a driver problem.
Also, if the Nintendo 64 games were playable before, please see the following information:
Q: Nemu crashes when I try to play a game I KNOW works! I've played it before on Nemu and it still works on other emus.
A: Ok, to fix this put both Nemu and the roms in directories with no spaces. What I did was put Nemu in my C:\, and my roms in a rom folder within Nemu's directory. So Nemu is located at (C:\Nemu08\), and the roms are located at (C:\Nemu08\Roms\)
