Clock Generator + Real-Time Clock

(Real-Time Clock - A record of the date and time is kept in the saved data.)

⚠To enable RTC, connect the cartridge reader to a PC and turn on the RTC setting.
Please turn on other settings as needed.
*HW3 setting must be turned on for it to work.

How to flash the Arduino

Uses a CR16xx (the same used by HW5) battery, which is located on the back of the PCB. 
Gives advanced users options:

  • The on-board 3.3V 1000mA (1A) linear regulator can be utilized to provide 3.3V to the main PCB allowing for an easy "headless" (serial-only) HW5 build or the use of an LCD module without a 3.3V out option.
  • Optional support to hardwire VBUS (+5V USB) to the module. This allows the RTC to remain powered by VBUS and not drain the battery when leaving the OSCR plugged in but powered off. 
  • Purple 4-layer PCB with ENIG (gold) finish.
  • Designed in the USA. Made in China.

Reads N64 roms and reads/writes save games(4K/16K Eeprom + Sram + all 3 types of Flashram)

⚠----------------------------

Notes on games with SA-1 and similar special chips:

This product does not include snesCIC.

To unlock cartridges with SA-1 you need both the Clock Generator and the snesCIC installed.
It's very important to provide the Nintendo Cart Reader with a high quality power source for dumping SA-1 games,not all USB ports will work. Best use a 5V/2A phone charger. An original iPhone or Amazon Fire Tab charger works great while a cheap Chinese phone charger might not unlock SA-1. Sometimes disabling the CLK1 switch will improve unlocking.
