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.
