Nestra is a dynamic recompiler which translates 6502 code into native code
to emulate a NES. Execution of the translated code is quite fast, and the
emulator can run at full speed with relatively modest CPU requirements.
The following keys may be used to control the program.
Typically move your player.
Reset the emulator.
Exit the emulator.
Adjust emulation speed. 1 is normal speed, 2 is double speed, etc.
Run at half speed.
Show disassembled code as the emulator runs.
Link branches directly after recompiling
(improves speed but may cause problems).
