The original power supply is actually a famicom psu (HVC-002) afaik, so this?:
Input: 100v AC 50/60Hz
Output: DC 10v 850mA (center negative)
Now I don't have a genuine fami psu but I do have a couple of options at hand, just wondering if option 1 is ok to try (damaging the psu in an attempt is fine btw I'm only concerned about the console).
Option 1 has removable tips to switch polarity.
Option 2 will require cutting the cable and switching wires around to get the right polarity (which is why I'm wondering if option 1 would work instead).
Option 1
Input: 100-240v AC 50/60Hz
Ouput: DC 9v 0.8A
Option 2
Input: 100-240v AC 50/60Hz
Output: DC 9v 1A
If both options are risky I can always try to source another psu (closer to spec) from junk, it's the right time of year for a lot of random shit to show up
Thanks in advance for any input.
