Power Adaptors / Famicom Power Supply

[nensondubois]

I got a Famicom Disk system off of ebay but it did not come with a power supply. I get error which is obviously because they're is no power going to the FDS. Is it safe to use a NES power supply that came with my NES? I tried that and I'm getting errors 21 and 22 is that because I'm using the wrong power supply?

Oy! Read through the thread or check the Workshop section on the site. I'd very strongly recommend you stop using the NES adaptor.

Yes...very sad..long, long time

I didn't know there were on-screen errors for power adapters on the FDS... then again I'm sure there's an error for everything.

The error messages are unrelated to your power supply. See here:

They are essentially saying that the disk failed an anti-piracy check.  In reality, though, it's probably your drive failing to read the disk for some reason (either the drive needs adjustment, or the disk itself is corrupt....yay floppies!).

I got it from ebay and the guy supposed replaced it with a genuine rubber belt but it came with no power supply so I used the one for my NES and I get error 2 which is a battery error so something is wrong here. I opened my French Doki Doki Panic and got error 22 after trying my Volleyball? Disk it came with.

Plausible explanation, pulled out of my technological a**:

• The FDS only uses its external power adapter to move the drive motor.


• The FDS power input has a rectifier diode in series as a reverse polarity protection.


• That diode would turn the NES adapter's 9VAC into something between 4.5 and 15 V pulsating DC


• The pulsating DC is moving the motor, therefore the motor is moving very slowly and/or stuttering


• The rest of the FDS logic is working OK, but thanks to the erratic movement of the motor the data is coming out garbled, and in consequence errors 21 and 22 (and possibly 27) are showing up.

Once again, I've repeated it countless times: DON'T use a NES adapter to power Famicom gear.

did I break my FDS?

Edit: I did not break my FDS. I tried it after buying 6 C batteries! I beat Doki Doki Panic with Mama!

Does that mean my plausible explanation was right?

Yes, don't use a NES adapter

Well I'm glad it works and I should be getting an adapter soon from

Is it necessary to use the original adapter with my Twin Famicom, or can use another adapter as. I've heard that a NES adapter is a no-go, but that I could use a Megadrive adapter. I'm not sure about this though and don't want to take any risk.

I use a multi volt adaptor for mine. Bought it cheap on eBay. Basically comes with a load of switchable connectors at the end so you can select the right voltage then use the correct bit. Does the job but I wouldnt recommend using any others from different consoles.

If you have the original AC adapter, use it connected to a 220 to 110V stepdown transformer.

PAL NES Adapter = NO GO indeed. I use a universal adapter with 7,5v and the correct pin (- / -) (don''t know which one). I can take a look when I got home.

Only problem with the Twin Famicom is a greyed palette on some (older) TV's in Europe.

[nintendodork]

Don't just plug in a regular Twin or Famicom adapter into any old outlet in Europe...
Calls for explosions...get a step-down converter and then make sure you have a compatible AC adapter.  You can't use a NES one or a FDS one if you were thinking about it

Thanks for the reactions.

Would this one be ok?
