+For ACK (TXLED aka PD5) and SS (RXLED aka PB0) you have to solder new headers or cables directly on the leonardo PCB (or you can use an Arduino Micro (not pro micro) which has everything broken out).

 LEDs will be dimmer due to 3.3v power. Using the 7V rumble motor line to Vin instead, and using NPN transistors like 2N2222A on MISO and ACK lines to prevent backfeeding voltage into the console will solve the issue (set INVERT_CIPO and INVERT_ACK to 1 in `ps2.c`).
