The porting of the NESBot Play the 'Tool Assisted Speedrun' videos on the real machine(NES). original (with Arduino): http://www.instructables.com/id/NESBot-Arduino-Powered-Robot-beating-Super-Mario-/ Almost same as the original, it need generated Key-input data by emulator with Lua script. See the original instructables' documents to know how to generate data file. BOM: mbed x1 NES x1 NES controller x1 4021(shift registor) x1

+// - The porting of the NESBot
+// original : http://www.instructables.com/id/NESBot-Arduino-Powered-Robot-beating-Super-Mario-/
+//
+// ported by Kaoru Shoji : http://mbed.org/users/kshoji
+//
+// - Connections:
+// a NES, a mbed and a 4021 (shift register) needed.
+//
+// for example) AV-FAMICOM(JPY) connector pinout
+// 1 LATCH (PL, P/S) -> mbed's 9 pin
+// 2 CLOCK -> 4021's 10 pin
+// 3 VCC -> 4021's 16 pin
+// 4 GND -> mbed's GND & 4021's 8 pin
+// 5 DATA -> 4021's 3 pin
+//
+// - Note:
+// The mbed's VCC must be supplied from USB cable.
+// If mbed's VCC is supplied from NES VCC, the LATCH signal detection may be failed.
+//
+// - How to use:
+// 0. Prepare the replay data with FCEUX and Lua script. (Lua script can be downloaded from instructables).
+// The data file needs to be placed into mbed's LocalFileSystem(on the root directory).
+// 1. NES power turn off.
+// 2. connect mbed to NES, and USB power.
+// 3. NES power turn on.
