Binary package “nestra” in ubuntu lucid

Nintendo Entertainment System emulator

 Nestra is a dynamic recompiler which translates 6502 code into native code
 to emulate a Nintendo Entertainment System. Execution of the translated
 code is quite fast, and the emulator can run at full speed with relatively
 modest CPU requirements. However, there is no sound support.
 .
 To use this program, you need NES ROMs which are not included.
